Answer:
Nose: Air is inhaled through the nostrils (and sometimes through the mouth) where it is filtered by the hairs and cilia to remove dust particles and moistened. The nasal cavity also moderates the temperature of the inhaled air.
Pharynx: This is a common passage for food, water, and air. It leads from both the nose and the mouth and leads to both the trachea (windpipe) and the oesophagus (foodpipe).
Larynx: This is the voice box situated just over the trachea and has a flap called the epiglottis which closes during swallowing to prevent food from entering the trachea and opens during breathing.
Trachea: Air now enters the windpipe which is situated behind the sternum (breastbone) and between the two lungs.
Bronchus: From the trachea, two bronchi (one bronchus for each lung) enter the lungs and divide and subdivide into secondary and tertiary bronchi, getting narrower as they proceed into the lung.
Bronchioles: The tertiary bronchi branch into fine tubules called bronchioles, the last passageways for air.
Alveoli:. Air ends its pathway in the alveoli (sing. alveolus) which are tiny sacs with very fine singe-celled walls. These alveoli are surrounded by capillaries that connect the pulmonary arteries and veins and that enable transfer of oxygen and carbon dioxide.
The pathway of air through the respiratory system starting with the external nares includes the nose, mouth, larynx, pharynx, lungs, and diaphragm.
Explanation:The pathway of air through the respiratory system starting with the external nares includes the following structures:
Nose: The major entrance and exit for the respiratory system.Mouth: A secondary opening for the respiratory tract.Larynx: Also known as the voice box, it connects the pharynx to the trachea.Pharynx: It is composed of three major sections: the nasopharynx, oropharynx, and laryngopharynx. It connects the nasal cavity and oral cavity to the trachea and esophagus.Lungs: The main organs of the respiratory system where gas exchange takes place.Diaphragm: A dome-shaped muscle that separates the chest and abdominal cavities and plays a role in breathing.Which level of organization is characterized by a group of cells that work together to perform a common function
Hey there! :D
Organization in organisms is like this:

A new object, Object Y, was discovered outside our solar system. Object Y is small and rocky, is not a satellite of any other object, and it does not have enough gravity to clear away smaller objects near its orbit. The characteristics of Object Y most closely resemble those of other (2 points)
comets.
dwarf planets.
moons.
meteors.
Answer:
The correct answer is comets.
Explanation:
Comet is an icy, small, and rocky bodies found in space, which discharge gas or dust. They are also called dirty snowballs. It is not considered as the satellite of other objects. It does not exhibit adequate gravity to clear away smaller objects close to its orbit. When it passes close to the Sun, it sheds extra of its ice, and its surface may get surrounded with darkish dirt and would seem more like an asteroid.
Final answer:
The characteristics of Object Y—being small and rocky, as well as its inability to clear its orbit—most closely resemble those of dwarf planets within our solar system.
Explanation:
The characteristics of Object Y most closely resemble those of other dwarf planets. Like Object Y, dwarf planets are small and rocky objects that do not have enough gravity to clear away smaller objects near their orbits. Although comets, asteroids, and meteors are also part of our solar system's collection of smaller objects, they each have distinct features that do not match the description of Object Y as closely as dwarf planets do. Comets are mostly icy and have elliptical orbits that can bring them close to the Sun, producing visible tails and comas. Asteroids are rocky like Object Y, but the term typically refers to those found within the asteroid belt between Mars and Jupiter, and they do not have the criterion related to clearing their orbits. Meteors are much smaller, often vaporizing in Earth's atmosphere, and moons are objects that orbit planets, which is not the case for Object Y.

The activation of receptor tyrosine kinases is characterized by A) channel protein shape change. B) dimerization and phosphorylation. C) a phosphorylation cascade. D) dimerization and IP3 binding. E) GTP hydrolysis
Answer:
B) dimerization and phosphorylation
Explanation:
Protein kinase receptors are simply saying receptors with associated kinases (usually tyrosine kinases).
Protein kinases are enzymes that have the ability to modulate other enzymes (or some other proteins) by adding the phosphate group. This is known as phosphorilation process. As a result of structural change, protein can change its activity (phosphorilation usually increase the activity).
Such receptors are involved in a many processes within an organism that are important for the cellular growth, differentiation, metabolism.
The activation of receptor tyrosine kinases involves dimerization, where two similar receptors bind together, followed by phosphorylation, which activates a downstream cellular response. A phosphatase enzyme eventually terminates this signal.
Explanation:The activation of receptor tyrosine kinases is characterized predominantly by dimerization and phosphorylation. Initially, a signaling molecule binds to the extracellular domain of the receptor which leads to its dimerization i.e., the joining of two receptor molecules. This allows their intracellular domains to come nearer and activate each other.
Following dimerization, the receptors undergo phosphorylation. Each receptor, within the dimer, catalyzes the addition of a phosphate group to tyrosine residues on the intracellular domain of the other receptor in the dimer. This process is referred to as 'autophosphorylation'. Autophosphorylation triggers a downstream cellular response which could involve various processes such as modifying cell metabolism, protein expression, or cell division. Lastly, a phosphatase enzyme terminates the signal by removing the phosphate groups from the phosphotyrosine residues.

Why is color blindness more common in males
Color blindness is more common in males due to the inheritance of the recessive gene on the X chromosome, and males have only one X chromosome.
Color blindness is more prevalent in males due to the genetic basis of the condition. The genes responsible for color vision are located on the X chromosome. Since males have one X and one Y chromosome (XY), while females have two X chromosomes (XX), a male inherits his X chromosome from his mother and the Y chromosome from his father.
If a male inherits a recessive color blindness gene on the X chromosome from his mother, he lacks the corresponding gene on the Y chromosome to compensate, leading to the manifestation of color blindness. In contrast, females would need to inherit two recessive genes (one from each parent) to express color blindness, making it less common in females. The genetic inheritance pattern on the sex chromosomes contributes to the higher incidence of color blindness in males.

Once a carousel is in motion, the constant movement of the carousel horse around the center of the circle can BEST be described as A) acceleration; change in speed. B) velocity; speed plus direction. C) acceleration; change in velocity. D) speed; distance traveled over time.
Answer:
its D
Explanation:
the facts are just all there
Answer:
C) acceleration; change in velocity.
Explanation:
When an object is moving around in a circulation motion with constant speed then even if the movement is constant still the velocity is changing at each point because of the change in the direction at each point. If the velocity is changing at each point then that means the object is accelerating.
But, in linear motion if an object has constant movement then the acceleration is considered zero because there is no change in the direction so velocity change is considered zero.
Since the carousel in this question is moving in the circular motion so it means that its direction is changing at each point which implies that its velocity is changing leading to acceleration.
Upon eating a hamburger in what organ is the chemical breakdown of its proteins initated
The chemical breakdown of proteins is initiated in the stomach by the enzyme pepsin and continues in the small intestine with additional enzymes from the pancreas.
Where Is the Chemical Breakdown of Proteins Initiated?
The enzyme pepsin, which is activated from its precursor form pepsinogen in the presence of hydrochloric acid (HCl), starts the process by breaking down proteins into smaller chains called polypeptides. This chemical reaction is crucial for protein digestion, allowing amino acids to be eventually absorbed into the bloodstream. As the partially digested proteins pass into the small intestine, they encounter additional digestive enzymes from the pancreas such as trypsin and chymotrypsin, which continue the process of breaking down the proteins into even smaller peptides and eventually into amino acids. These amino acids are then absorbed through the intestinal wall and into the bloodstream, where they are carried to the liver for further processing.
Approximately how many piglets a sow have in a litter
Answer:
10
Explanation:
The pigs tend to have very large litters. A sow that has been fed and kept well usually has around 10 piglets per litter. While 10 piglets are somewhat the normal number, there are many cases when a sow has produced 15 or 20 piglets per litter. Not just that the liters are very large, but a sow can produce not one, but two litters per year, making it an animal that has extremely quick reproductive cycle for its size. The gestation period is also not long for the size of these animals, and it usually lasts between 112 and 120 days. When the piglets are born they are very small and helpless at first, but they manage to grow and mature very quickly, reaching sexual maturity at only between 3 and 12 months of age, thus becoming adults in a very short time span.
Tadpoles must undergo a major metamorphosis to become frogs. This change includes reabsorption of the tail, growth of limbs, calcification of the skeleton, increase in rhodopsin in the eye, development of lungs, change in hemoglobin structure, and reformation of the gut from the long gut of an herbivore to the short gut of a carnivore. Amazingly, all of these changes are induced by thyroxine. What is the most likely explanation for such a wide array of effects of thyroxine?
Answer:
There are many receptors for thyroxine on different target cells (tissues), so its effect can be huge
Explanation:
Target cell for a certain hormone is a cell that have hormone receptor specific for that hormone. There are two main types of receptors on target cell:
cell membrane receptors (also called trans membrane receptors)-usually for peptide hormones, such as insulinintracellular receptors (also called nuclear receptors)-usually for steroid hormones, such as testosterone.Hormone binding to the receptor leads to the signal cascade within the cell, which results in cell response.
Receptors for thyroid hormones are nuclear receptors.

How does carbon enter the biotic part of the ecosystem
Answer:
Photosynthesis
Explanation:
Photosynthesis can be defined as the process in which the plant and other organism convert light energy into chemical energy which can further be used to make organic compounds. Similarly, it is a process that removes carbon dioxide from the atmosphere and then uses it to make organic compounds.
Answer:
Photosynthesis
Explanation:
When plants die, their carbon compounds are converted into carbon dioxide by the action of saprophytic bacteria and fungi. The carbon dioxide is released back to the atmosphere. If dead bodies of plants are buried in highly acidic or anaerobic conditions, they cannot be acted upon by saprophytes. Instead they are partially decomposed by anaerobic bacteria and accumulate forming peat. Heat and pressure build up in the peat converting it to coal and natural gas that can be combusted to release carbon.
In general, sympatric speciation requires the action of _____ selection acting against hybrids.disruptivedirectionalecologicalartificialstabilizing
Answer:
disruptive
Explanation:
Sympatric speciation is a speciation (evolution of new species) that occurs when one group of population becomes isolated, but stays in the same geographic location as the rest of the population. Through time, these two group evolve independently and become different species.
The model that shows this type of speciation involves disruptive selection: homozygous individuals are favoured over heterozygous in a population, which leads to speciation.
Sympatric speciation generally requires disruptive selection, which favors extreme phenotypes, leading to reproductive isolation and creation of new species within the same habitat.
Explanation:In general, sympatric speciation requires the action of disruptive selection acting against hybrids. Disruptive selection plays a crucial role in sympatric speciation by favoring extreme phenotypes over intermediate ones, thereby driving the divergence within a population sharing the same habitat. This pattern of selection can eventually lead to reproductive isolation and form new species without physical barriers. It contrasts with directional selection which favors one extreme phenotype and stabilizing selection that favors the intermediate phenotype, or artificial selection that is influenced by human choice.
What climate condition occurs during El Niño?
dry heat throughout North America
warm water moving toward the coast of South America
heavy rain moving toward the coast of South America
flooding throughout North America
Answer:
Warm water moving toward the coast of South America
The correct answer is B. Warm water moving toward the coast of South America
Explanation:
El Niño is a phenomenon in the climate that mainly occurs as warm ocean water develops in the Pacific Ocean especially in the Equator Pacific including the coast of South America. This causes changes in pressure due to the temperature in the ocean water as well as changes in the rain. Additionally, this phenomenon is the opposite of the one of La Niña in which the temperature in the ocean is colder rather than warmer. Also, these types of climate changes are part of cycles that last around a year but can take place over multiple years. Therefore, the climate condition that occurs during this phenomenon is warm water moving toward the coast of South America.
Where does the energy for photosynthesis come from?
Answer:
From the sunlight (together with CO2 and water)
Explanation:
Photosynthesis is a process performed by the plants (also some algae and bacteria) in which the energy of sunlight is transformed into chemical energy usable by those plants. Necessary components of this set of reactions are sunlight, water and CO2, while resulting products are glucose and oxygen. Products of photosynthesis are then used in the metabolic processes known as cellular respiration. During the cellular respiration, glucose and oxygen are used for the production of ATP, CO2 and water. Cellular respiration is performed in all living organisms.
Photosynthesis occur in the chloroplast, membrane organelles with photosynthetic pigments (such as chlorophyll).
The energy for photosynthesis comes from the sun. Plant-based organisms capture this energy and convert it into a form that is usable by all life through a process known as photosynthesis. This process underpins much of the energy transformation that supports life.
Explanation:The energy for photosynthesis comes from the sun. In this process, green plants, algae, cyanobacteria, and photosynthetic protists capture solar energy and convert this into chemical energy necessary for life - a process known as photosynthesis. This process transforms the radiant energy in sunlight into stored chemical energy.
Part of this process involves using light energy from the sun to transform carbon dioxide and water into glucose and oxygen. Other organisms consume these glucose-bearing plants and use the glucose to create ATP, a molecule used for energy storage in cells.
Overall, it's the energy from the sun that is harnessed through the process of photosynthesis that provides most of the energy required by living organisms on earth. Without the solar energy captured during photosynthesis, life as we know it would not exist.

What is meant the description "antiparallel" regarding the strands that make up DNA?
A) The twisting nature DNA creates nonparallel strands.
B) The 5' to 3' direction of the other strand runs counter to the 5' to 3' direction of the other strand.
C) Base pairings create unequal spacing between the two DNA strands.
D) One strand is positively charged and the other is negatively charged.
E) One strand contains only purines and the other contains only .
Answer:
B) The 5' to 3' direction of the other strand runs counter to the 5' to 3' direction of the other strand.
Explanation:
Two strands in DNA double helix are in opposite directions alongside each other and that is called antiparallel orientation.
The 5' end of nucleic acid refers to phosphoryl end (phosphate group) while 3' end refers to hydroxyl (OH) group.
The property of anti-parallelism is important for the process of DNA replication.
In terms of DNA, 'antiparallel' describes the opposite orientations of the two strands in a DNA double helix, with one strand running 5' to 3' and the other 3' to 5', allowing proper base pairing and function of DNA-synthesizing enzymes.
Explanation:The term antiparallel in the context of DNA refers to the orientation of the two strands that make up the DNA double helix. They are parallel but run in opposite directions. Specifically, one strand is oriented 5' to 3', while the complementary strand is oriented 3' to 5'. This arrangement is crucial for the DNA's functions, such as replication and repair, and it allows the enzymes that synthesize DNA, like DNA polymerase, to operate properly. Because the DNA strands are antiparallel, complementary base pairs can form the correct hydrogen bonds, with adenine (A) always pairing with thymine (T) and guanine (G) always pairing with cytosine (C).
A worm would stand a poor chance of being fossilized because ________.
Answer:
Explanation:
because it has no bones
A worm has a low likelihood of fossilization due to its soft body structure and its living habitat which doesn't favor the fossilization process.
Explanation:A worm would stand a poor chance of being fossilized primarily for biological and environmental reasons. Worms, like many other soft-bodied creatures, are less likely to become fossilized because they lack hard parts such as bones, shells, or teeth which are most typically preserved in the fossil record. In addition, worms live in environments which typically do not lend themselves well to the fossilization process.
For fossilization to occur, an organism's remains usually need to be covered by sediment or other material soon after death to prevent decay and scattering by scavengers. A worm's habitat in the soil doesn't often provide these conditions, decreasing its chances of fossilization.

A. adenosine diphosphate; a phosphate group
B. adenosine monophosphate; three phosphate groups
C. adenosine triphosphate; a phosphate group
D. adenosine diphosphate; three phosphate groups
Final answer:
When ATP is broken down, it produces adenosine diphosphate (ADP) and an inorganic phosphate group (Pi). This process releases energy due to the lower free energy of the products compared to the reactants.
Explanation:
When ATP is broken down in cells, the products are adenosine diphosphate (ADP) and an inorganic phosphate group (Pi). This process is known as hydrolysis, which is the reaction involving the cleavage of bonds by the addition of water. ATP, consisting of an adenine, a ribose, and three phosphate groups, releases energy when the bond between the second and third phosphate groups is broken. This energy release occurs because the products, ADP and Pi, have considerably lower free energy than the reactants, ATP and a water molecule. Hence, the correct answer to the question is:
A. adenosine diphosphate; a phosphate group

The answer is C) cortex
The majority of glomeruli are located in the cortex of the kidney, where they form part of the renal corpuscles and are adjacent to the tubular structures involved in urine formation.
Explanation:The majority of glomeruli are located in the cortex of the kidney. This region of the kidney houses all of the renal corpuscles as well as the proximal convoluted tubules (PCTs) and distal convoluted tubules (DCTs). Some nephrons within the cortex are termed cortical nephrons and have a shorter loop of Henle that does not extend beyond the cortex, whereas about 15 percent of nephrons, which are called juxtamedullary nephrons, have long loops of Henle that plunge deep into the medulla.
The other options provided do not accurately describe the location of the majority of glomeruli. The vasa recta and medulla house the renal pyramids and longer loops of Henle associated with juxtamedullary nephrons, pelvis is the area into which the renal pyramids drain before connecting to the ureter, and calyces are the chambers that collect urine before it passes into the renal pelvis.
During interphase a cell grows duplicates organelles and
Answer:
it copies the DNA of both parent cells
Explanation:
Interphase is a cell cycle stage where the cell grows, duplicates its organelles, synthesizes DNA, and prepares for mitosis, which is followed by cytokinesis to form two daughter cells.
Explanation:During interphase, a cell undergoes growth, duplicates its organelles, and prepares for cell division. This phase is characterized by three distinct stages: the G1 phase (also known as the first growth phase), the S phase (DNA synthesis), and the G2 phase. In the G1 phase, the cell grows in size, performs normal metabolic processes, and starts replicating organelles. Entry into the S phase marks the beginning of DNA replication to ensure each new cell has an identical set of genetic material. Finally, in the G2 phase, the cell continues to grow, makes additional proteins and organelles, and prepares for mitosis. The mitotic phase follows interphase, which includes the processes of mitosis and cytokinesis, resulting in the formation of two genetically identical daughter cells.
