In this system, the solute cannot pass through the selectively permeable membrane. A principle of diffusion is that the molecules move around and will spread evenly throughout the medium if they can. However, only the material capable of getting through the membrane will diffuse through it

A selectively permeable membrane affects diffusion by allowing only certain molecules to pass, based on characteristics like size or charge, through processes like simple and facilitated diffusion. Oxygen and carbon dioxide are examples of molecules that diffuse directly through the membrane, while larger substances require facilitation.

A selectively permeable membrane affects diffusion by allowing only certain molecules or ions to pass through it, while restricting others based on size, charge, or chemical composition. This mechanism is crucial for maintaining cellular homeostasis and enabling efficient nutrient intake and waste removal. Diffusion is a passive transport process, meaning it does not require energy and moves substances from an area of high concentration to low concentration. Smaller molecules easily diffuse across a cell membrane, but larger ones may require facilitated diffusion which involves protein channels or carriers to assist in their transport.

Simple diffusion allows nonpolar and small polar molecules, like oxygen and carbon dioxide, to pass directly through the phospholipid bilayer. In contrast, facilitated diffusion is necessary for larger or polar molecules, such as glucose and ions, which cannot diffuse directly through the lipid bilayer. There are two types of facilitated diffusion: one uses protein channels that provide a passageway for specific substances, and the other uses carrier proteins that bind to a molecule and change shape to shuttle it across the membrane. Both methods rely on the concentration gradient but do not require energy, distinguishing them from active transport processes.

Examples of phospholipid-soluble molecules include oxygen and carbon dioxide, which can move across the cell membrane through simple diffusion. Their movement direction is influenced by concentration gradients, ensuring that they move from regions of high concentration to regions of lower concentration without the expenditure of energy.

Cytokensis is the physical process of cell division. It divides the cytoplasm of a parental cell into two different daughter cells.

In plants, a cell wall forms. Cytokensis occurs in mitosis and meiosis. The objective for cytokensis is to divide the parent cell into two daughter cells. So cytokensis in plants is when a cell wall forms in between the daughter cells. Plant cells have walls, so they CANNOT divide using a cleavage furrow. A cell plate forms across the cell during telophase.

In animal cells, cleavage furrow forms. This pinches the cell in half and forms two different cells.  

A cleavage furrow is an indentation that appears in the cells surface when the cell is preparing to divide.

So, let's review our options:

A: Animal cells get pinched into two daughter cells by the cell membrane; the plant cell has to form a cell plate before it can create daughter cells.

This would be the correct answer. The only main difference between animal cell cytokensis vs plant cell cytokensis is the cell wall that animal cells lack. Animal cells get pinched into two daughter cells, by the cleavage furrow in the cell membrane, while the plant cell has to form a cell plate before it can create daughter cells.

B: Animal cells give daughter cells a full set of chromosomes at the time of division; plant cells give daughter cells a half set of chromosomes. .

This can be disproven. In meosis, a cell divides into four cells that have half the number of chromosomes. In mitosis, all chromosomes are kept. Both Plant & Animal cells both reproduce using both both meosis and mitosis, so this option is irrelevant.

C: Animal cells require an extra grow phase before cytokensis; plant cells move straight to cytokensis.

Both animal cells and plant cells have the same amount of "grow phases" before cytokensis. This option is irrelevant.

D: Animal cells begin cytokensis during anaphase, plant cells begin around the same time as telophase.

They both begin during the same time. This option is also irrelevant.

Animal cells undergo cytokinesis through the pinching of the cell membrane, while plant cells form a cell plate to divide the cytoplasm. Animal cells provide daughter cells with a full set of chromosomes, while plant cells give daughter cells a half set of chromosomes. Animal cells require an extra growth phase and begin cytokinesis during anaphase, while plant cells move straight to cytokinesis and begin around telophase.

In animal cells, cytokinesis occurs by the pinching of the cell membrane, forming a constriction known as the cleavage furrow. On the other hand, plant cells form a cell plate that eventually develops into a cell wall, dividing the cytoplasm into two daughter cells.

Additionally, animal cells provide each daughter cell with a full set of chromosomes, while plant cells give each daughter cell a half set of chromosomes.

Moreover, animal cells require an extra growth phase before cytokinesis, while plant cells directly transition to cytokinesis. In animal cells, cytokinesis begins during anaphase, while plant cells start cytokinesis around the same time as telophase.

The false statement is: D. occurs in animal but not plant cells  

Because cellular metabolism occurs in all living organisms. Cellular metabolism refers to all of the set chemical reactions within the living system, so it includes complex and controlled biochemical reactions - metabolic pathways, that can be anabolic (synthesis) or catabolic (break down of molecules). The processes of metabolism are necessary for organisms to grow and reproduce, maintain their structures, and respond to environmental changes.

Cellular metabolism occurs in both animal and plant cells.

The false statement about cellular metabolism is D. Cellular metabolism occurs in both animal and plant cells.

Cellular metabolism encompasses a series of biochemical reactions that occur within a cell to maintain life processes. It includes various processes such as catabolism and anabolism, which require different conditions.

Cellular metabolism can occur within organelles, such as the mitochondria and chloroplasts, where specific metabolic processes take place. It also involves the synthesis of various molecules, including steroid hormones.

Furthermore, cellular metabolism often occurs on the surfaces of internal membranes, where enzymes and other molecules are localized for efficient metabolic reactions.

The correct answer is: 24 chromosmes.

Mitosis is the cell division of somatic cells (all cells except gametes) in which mother cell produce two identical daughter cells with the same number of chromosomes as she had.

During the S phase of interphase, replication occurs and the genetic material of a cell is duplicated. There are still 24 chromosomes but they exist in a X shape structure-two sister chromatids (genetically identical). So, there are 24 chromosomes, but 48 chromatids. Sister chromatids separate during the anaphase of mitosis and each chromatid is then considered a separate, individual chromosome. After division and cytokinesis, the normal chromosome number is restored to the cell.

Explanation:

During the capillary stagnation phase of hemorrhagic shock, blood flow is regulated by precapillary sphincters. If they are closed, due to influences like arteriole constriction, blood bypasses the capillary beds and flows directly from arteriole to venule.

During the capillary stagnation phase of hemorrhagic shock, the body regulates blood flow based on its needs, directed by nerve and hormone signals. This is controlled by small muscles called precapillary sphincters. If the sphincters are open, blood will flow into the associated branches of the capillary blood. But, if all of the sphincters are closed, blood will flow directly from the arteriole to the venule, bypassing the capillary beds.

Arteriole constriction is triggered by certain regulators causing the release of vasoconstricting substances like endothelins from endothelial cells. This constriction could cause the pre-sphincter muscle to close, temporarily halting blood flow to that region. This is one of the responses the body may have during the stagnation phase of hemorrhagic shock.

During the capillary stagnation phase of hemorrhagic shock, the body induces vasoconstriction to preserve core perfusion by constricting blood vessels, including the arterioles and precapillary sphincters, through the release of endothelins and prostaglandins. This response decreases blood flow to the capillaries and can lead to tissue ischemia and hypoxia.

During the capillary stagnation phase of hemorrhagic shock, there are significant changes in blood flow regulation within the microcirculation. The precapillary sphincters, which are circular smooth muscle cells, play a critical role in this process. Under normal conditions, these sphincters regulate the flow of blood into the capillaries based on the metabolic needs of the tissue. If the surrounding tissue requires oxygen and needs to eliminate waste products, the precapillary sphincters will open to allow blood flow. Conversely, they close to restrict the flow when necessary.

In hemorrhagic shock, the body responds by triggering vasoconstriction, the narrowing of blood vessels, to preserve core organ perfusion by diverting blood away from less vital regions. This response involves the release of endothelins, which are powerful vasoconstricting peptides, and other constricting factors like platelet secretions and prostaglandins. The constriction of arterioles and precapillary sphincters can minimize blood loss and maintain arterial pressure, but it also leads to reduced perfusion of the capillary beds, creating a stagnation phase where blood flow is significantly compromised, potentially leading to tissue ischemia and hypoxia.

ATP is adenosine triphosphate composed of a nitrogenous base (adenine), the sugar (ribose), and the triphosphate.

Energy used by the body to perform muscular contractions and many other energy-required functions is adenosine triphosphate or ATP. The most important function of ATP is its ability to store and transport chemical energy within cells. That energy can be used for many chemical processes such as muscle contraction, nerve impulse propagation, chemical synthesis.. When consumed in metabolic processes as an energy source, it becomes converted either to adenosine diphosphate (ADP) or to adenosine monophosphate (AMP) because one or two phosphate groups are released (hydrolysis of high-energy bonds). Since ATP is a nucleoside triphosphate it can be used for the synthesis of nucleic acids.

Adenosine triphosphate (ATP) consists of the sugar ribose and the nitrogenous base adenine, along with three phosphate groups.

Adenosine triphosphate (ATP) is composed of the sugar ribose, which is a pentose sugar (a five-carbon sugar), and the nitrogenous base adenine. Adenine is a purine base, one of the two types of nitrogenous bases found in nucleic acids. In ATP, ribose is attached to adenine, forming adenosine. Additionally, ATP contains three phosphate groups attached to the ribose sugar. These phosphate groups are the key to ATP's function as an energy carrier in cells. The bonds between the phosphate groups are high-energy bonds, and when these bonds are broken through hydrolysis, energy is released, which can be used by cells for various cellular processes.

The correct question is:

What sugar and base molecules are found in ATP?

Protein deficiency is caused by the small amount of protein you eat to maintain normal body function. Not consuming enough protein can cause muscle cramping, weakness and soreness and hair loss too. Beans are the best to eat whenever it is possible. If you're vegan, then 2 cups of carrots are the best too.

So choice B

Final answer:

Nina should include beans in her diet to address her protein deficiency, as they are high in protein and offer additional health benefits. Other protein-rich foods she might consider are lean meats, poultry, eggs, seafood, nuts, and seeds.

Explanation:

Nina, who is suffering from protein deficiency, would benefit from incorporating foods into her diet that are rich in protein to help address her nutritional needs. Of the options provided (rice, beans, carrot, lettuce), beans are the best choice as they are a good source of protein, particularly for individuals who may not consume meat. Beans, as part of the legume family, not only provide protein but also essential fibers, vitamins, and minerals that are beneficial for overall health.

Rice, carrots, and lettuce provide other nutrients but are not as high in protein. Hence, for someone like Nina who requires an increase in dietary protein, beans are recommended. Additionally, other protein-rich foods that Nina might consider include lean meats, poultry, eggs, seafood, nuts, seeds, and soy products. These foods provide varying amounts of protein along with other important nutrients.

While meat, eggs, and dairy products are known for their high protein content, it's important to note that there are also many plant-based proteins that can help to fulfill dietary requirements. These include not only beans but also lentils, peas, whole grains, and soy products. These foods can be particularly useful for vegetarians or those looking to reduce their meat consumption without compromising on their protein intake.

There are many reasons for this. First of all, any water from Earth's surface can flow into the ocean due to gravity. There are also glaciers in the ocean that can melt. In the water cycle, the ocean, the atmosphere, and the land continuously exchange moisture among each other. Because weather patterns form and dissipate slower over the water than over the land, there is more circulation occurring in the atmosphere above the land. Therefore, there's more cloud formation.

Precipitation is less common on land than over the oceans primarily because a larger volume of water vapor is generated over the oceans. This is due to the vast ocean surfaces which facilitate evaporation. Since most evaporated water precipitates back into the oceans, less is available to be transported over land.

The water cycle describes the continuous movement of water on, above, and below the surface of the Earth, where it changes states among liquid, vapor, and ice. The oceans, which hold over one billion cubic kilometers of water, are the main source of evaporation due to the large surface area and abundant solar heat. About 400 thousand cubic kilometers of water vapor are produced from the oceans annually, but most of it falls back as precipitation over the ocean itself. Only about 40 thousand cubic kilometers are transported as atmospheric moisture from the oceans to land, where it adds to the 70 thousand cubic kilometers of recycled water from evapotranspiration on land. Consequently, the lesser amount of water vapor available over land compared to over the oceans results in less precipitation.

Answer:

e) Sons and daughters have equal probabilities in inheriting a recessive allele of an X-linked gene from their mother, but only sons can inherit rare Y-linked genetic disorders from their father.

Explanation:

Females have two copies of the X chromosome and males have only one X chromosome (one Y chromosome). Because of that X-linked recessive diseases are more common among males than females (males need only one copy to have disease, females with one copy are carriers).  

For example, if a mother is a carrier (has only one allele that is associated with disease), she can transmit either the X chromosome with the mutation or an unaffected X chromosome to her children. If the father is unaffected, all of the daughters will be unaffected—since they will inherit at least one normal X chromosome from their father. But, son can be affected, because he inherits Y chromosome from father and can inherit affected X chromosome from mother.

X-linked genes differ from Y-linked genes in several ways, including the inheritance patterns and the types of characteristics they affect.

X-linked genes differ from Y-linked genes in the following ways:

The correct answer is: C) the extraction of energy from high-energy electrons remaining from glycolysis and the citric acid cycle

Electrons from electron carriers (NADH and FADH from glycolysis and citric acid cycle) donate electrons to the electron transport chain and that causes changes in protein complexes of electron transport chain. As a consequence, protein complexes pump H+ across a selectively permeable cell membrane from the mitochondrial matrix into the intermembrane space of mitochondria.  H+ can only get back and pass through the inner mitochondrial membrane with the help of ATP synthase (down their electrochemical gradient). ATP synthase turned by the force of the H+ diffusing through it forms ATP by adding a phosphate to ADP. This type of ATP synthesis  is called oxidative phosphorylation and it is based on chemiosmosis-movement of ions across a selectively permeable membrane.

Explanation:

The correct answers are:

- Faults form in the lithosphere;

- Plates slide in opposite directions;

The transform plate boundaries are plate boundaries where the two or more plates are sliding past each other, moving in opposite directions. Because of the sliding, a lot of pressure is created on the plate boundary, so the earthquakes are a common occurrence. Also, something that is a characteristic of this type of plate boundary are the faults, to be more specific, transform faults. The transform faults are parallel to the plate boundary, and it can be a single one, or multiple faults parallel to one another. Their depth also can vary, from few meters to several tens of meters, or even more.

Convergent Plates causes to ocean floors to expand.

The trait you are showing may be a recessive gene, so your parents have a dominant gene and the recessive gene. The dominant gene is the one being shown by your parents.

It would be possible for you to show a trait when neither of your parents shows it. This actually happened due to the expression of recessive genes. This is because these types of genes possess traits that are skipped between generations.

Genetic traits may be characterized as the expression of any character in the individual. In a more simple sense, traits may also be defined as the measurement of character within any organism.

According to the context of this question, the trait that you are expressing may depend on the recessive gene, when both of your parents express the genes, they are localized and referred to as dominant traits. These traits will never be skipped in a generation and would definitely express in each and every generation.

Therefore, it would be possible for you to show a trait when neither of your parents shows it.

The kidney releases erythropoietin, a hormone that functions in the maturation of white blood cells

This is not the function of urinary system, because erythropoietin secreted by the kidney stimulates red blood cell production (erythropoiesis) not white blood cells. Erythropoietin also called hematopoietin is secreted as a response to hypoxia (Insufficient oxygen). Elevated levels of this glycoprotein are usually in disorders such as anemia, and hypoxemia (extremely low oxygen levels) due to chronic lung disease.

Among the stated choices, the function that is not performed by the urinary system is 'The kidney releases erythropoietin, a hormone that functions in the maturation of white blood cells.' Erythropoietin, produced by the kidneys, is involved in the production of red blood cells instead.

The urinary system serves several crucial functions including the excretion of metabolic wastes, maintenance of water-salt balance, pH balance, and the production of hormones such as erythropoietin, which triggers the formation of red blood cells. However, among the stated functions in the question, the following is NOT a function of the urinary system: 'The kidney releases erythropoietin, a hormone that functions in the maturation of white blood cells'. While the kidney does release erythropoietin, it is actually involved in the maturation and production of red blood cells, not white blood cells.

The correct answer is: b. phosphorus and nitrogen  

Plants use organic matter nutrients that produce by their own and thus we classified them as autotrophs (or self-feeders). But, they also require inorganic nutrients such as nitrogen and phosphorus and often one of them is special nutrient needed for growth and because of that called the limiting nutrient.

The fertilizers that people apply to farm fields, gardens and lawns contain phosphorus and nitrogen.

Answer:

B (Phosphorus and Nitrogen)

Explanation:

Plants are unique organisms that can absorb nutrients and water through their root system. An essential nutrient is one required by an organism for normal growth and development, but which it cannot manufacture on its own. Plant nutrients can be organic or inorganic depending on whether or not it contains carbon.

Because plants can manufacture all the organic nutrients they need, they have no essential organic nutrients, however, they need to take in specific inorganic nutrients to sustain their growth.

The soil supplies some of these inorganic nutrients in relatively large amount. These nutrients called MACRONUTRIENTS include Nitrogen, Phosphorus, Pottasium, Calcium, Sulfur, Magnesium etc.

Nitrogen is a major component of organic compounds (amino acids, nucleic acids; DNA and RNA, chlorophyll). Nitrogen-deprived plants become pale green or yellow, due to a lack of chlorophyll, a condition known as chlorosis.

Like Nitrogen, Phosphorus is involved with many vital plant processes. It is present mainly as a structural component of nucleic acids (RNA and DNA). It is also a vital part of Adenosine triphosphate (ATP) in all living things, including plants.

Since it's a small amount that someone left behind, it's a trace amount.

Final answer:

The correct answer to the student's question is 'A. actin and myosin sliding past each other and partially overlapping', which describes the mechanism of muscle contraction according to the sliding filament model.

Explanation:

The sliding filament model of contraction describes the process by which muscle cells contract. The key to this model is that the sarcomere, the fundamental unit of muscle contraction, shortens as the thick (myosin) and thin (actin) filaments slide past each other without changing their own lengths. This sliding enables the sarcomeres to shorten, which leads to the overall shortening and contraction of the muscle fiber. During this process, the myosin heads bind to actin forming cross-bridges, and as they pull on the actin filaments, the sarcomere shortens. According to the options given, the correct answer would be 'A. actin and myosin sliding past each other and partially overlapping', as the other options incorrectly describe the mechanism of muscle contraction dictated by the sliding filament model.

Final answer:

Primary consumers, usually herbivores, get their carbon from eating producers like plants, which make organic compounds through photosynthesis.

Explanation:

Primary consumers obtain their carbon from the organic compounds present in producers such as plants or photosynthetic bacteria. These primary consumers, which are typically herbivores, ingest the producers and break down the carbon compounds via respiration, especially aerobic respiration, which requires oxygen and releases carbon dioxide. The organic compounds that primary consumers feed on are originally synthesized by producers through the process of photosynthesis, using carbon dioxide from the atmosphere or in dissolved forms, like bicarbonate in water bodies.
