A certain organelle is part of the endomembrane system of a cell and looks like flattened sacs of membranes. It is often referred to as the "post office" of the cell because it sorts, modifies, and repackages proteins and lipids. It then ships the products in vesicles to other parts of the cell or to the plasma membrane, where they may exit the cell. However, this organelle does not participate in the synthesis of proteins and lipids. Identify this organelle.
Answer:
Golgi apparatus
Explanation:
The endomembrane system includes the nuclear envelope, the endoplasmic reticulum, the Golgi apparatus, lysosomes, several types of vacuoles, and the plasma membrane.
The Golgi apparatus consists of flattened membranous sacs called cisternae. They are stacked upon each other. The membrane of each cisterna in a stack maintains the unique internal space from the cytosol. Proteins and lipids formed on the ER are packed in many transport vesicles and are delivered to the Golgi apparatus.
The Golgi apparatus serves as a site for modification, and packaging of proteins and lipids. Modification of proteins in the Golgi apparatus results in the formation of several types of modified biomolecules such as glycoproteins. It serves as the site for the packaging of secreted proteins and sorting of other proteins to vacuoles and other organelles via transport vesicles. The transport vesicles carrying various biomolecules are formed in the trans face of the Golgi apparatus. These vesicles pinch off from the Golgi membrane and transport their contents to a specific destination.
The organelle in question is the Golgi apparatus, which sorts, modifies, and repackages proteins and lipids, then sends them to other parts of the cell or outside the cell.
Explanation:The organelle you're referring to is known as the Golgi apparatus. Often likened to the 'post office' of a cell, the Golgi apparatus is responsible for packing, sorting, and modifying proteins and lipids once they've been synthesized in the cell. These substances are then transported via vesicles to other parts of the cell for use, or to the plasma membrane to be excreted from the cell. However, as you mentioned, the Golgi apparatus doesn't participate in the actual synthesis of these proteins and lipids.

Which of the following types of receptors are located in the mouth?
A. chemoreceptors only chemoreceptors, thermoreceptors, and nociceptors
B. only chemoreceptors, mechanoreceptors, thermoreceptors, and nociceptors
C. thermoreceptors, mechanoreceptors, and nociceptors only
Final answer:
The mouth contains chemoreceptors, mechanoreceptors, thermoreceptors, and nociceptors. These receptors are essential for the comprehensive perception of taste, texture, temperature, and potential pain from food consumption. The correct answer is B, which includes all four types of receptors.
Explanation:
The types of receptors located in the mouth include chemoreceptors, which are responsible for the sense of taste, as well as sensing chemical stimuli like odor; thermoreceptors, which detect temperature changes; mechanoreceptors, which can sense mechanical pressure and touch; and nociceptors, which are responsible for the sensation of pain. These receptors work together to provide us with a comprehensive sense of our food's taste, texture, and temperature and can signal if a food is harmful or too hot, potentially causing pain. Therefore, the correct answer to the question is B: only chemoreceptors, mechanoreceptors, thermoreceptors, and nociceptors.
Chemoreceptors are mainly found in taste buds on the tongue and are essential for detecting the five primary tastes: sweet, sour, bitter, salty, and umami. Thermoreceptors are part of the protein family that allows us to sense temperature changes, including the warmth or coolness of foods. Mechanoreceptors respond to physical stimuli like pressure and vibration, crucial for detecting the texture and consistency of food. Nociceptors alert us to potential damage, such as the pain experienced from consuming something too hot or too spicy, which can cause chemical irritation.
How did you develop from a single-celled zygote to an organism with trillions of cells?
Answer: mitosis
Explanation:when an egg is fertilized,it becomes a zygote.the zygote is single-cell and undergoes cleavage.cleavage is the mitotic division of a zygote into smaller cells also called blastomere,which forms a spherical mass.
The type of cleavage is dependent on the different animals and whether yolk is present.
As the zygote continues to grow,organs rudiments forms and organs form afterwards, through mitotic division.
In Mitosis the daughter cell has the same number of chromosomes as the parent cell and it is essential in the increase of the number of cells causing growth in multicellular organisms.
Mitosis also helps to regenerate lost body parts.
In what type of circulation does the blood flow between the heart and lungs?
Answer:
Pulmonary circulation
Explanation:
The pulmonary circulation is the type of circulatory system that involves the flow of deoxygenated blood from the right ventricle of the heart to the pulmonary trunk, which transports the deoxygenated blood through the right and left pulmonary arteries to the capillary beds and arterioles of the lungs. An exchange occurs in the lungs as oxygen is absorbed from the alveoli, while carbon dioxide is released. The oxygenated blood is then returned to the left atrium and ventricle of the heart.

When sea otters are present in a kelp forest community, there are more than 12 species in the community. If sea otters are removed, there are 5–7 species that remain in the community. These data suggest that sea otters are:
Answer:
A keystone species
Explanation:
Keystone species are the species that play an important role in maintaining the structure of the ecological community they live in and they do so by affecting the numbers and types of other organisms that are found in the same ecological community. A keystone species may not necessarily occupy the largest biomass or be the greatest in terms of productivity in the given community but the removal of keystone species has a huge impact on the survival of other species and hence, the term keystone is used. In the given example, the sea otters are also playing the role of keystone species in a kelp forest community as in their presence there are more than 12 species however once these species are removed, the number reduces down to 5-7.Only a small amount of the energy stored in food is available to the next organism in a food chain because:
Answer:
because 90% of energy is lost in the environment as heat.
Explanation:
According to the 10% rule, only 10% of energy is transferred from one trophic level to the next trophic level. It means that if the producers have 100% percent energy than only 10% of energy will be passed from producers to primary consumers.
So only a small amount of energy is transferred to the next trophic level because most of the energy is lost as heat during the oxidation of food. Therefore a very small amount of energy is transferred to the highest trophic level.
As less energy is available to support the organisms present on higher trophic level so their number is lower than the number of organisms present at lower trophic levels.
The correct option is D i.e. most of the energy is used for life processes.
In a food chain, most energy is used for life processes or lost as heat, limiting the amount of energy available to the next organism. This explains why food chains rarely exceed four or five trophic levels.
In a food chain, most of the energy is used for life processes or lost as heat. This is due to the second law of thermodynamics, which states that energy is lost as it is transferred from one trophic level to the next. For example, in the Silver Springs ecosystem study by Howard T. Odum, primary producers generated 20,819 kcal/m²/yr, but this energy reduced significantly as it moved up the chain: primary consumers generated 3368 kcal/m²/yr, secondary consumers 383 kcal/m²/yr, and tertiary consumers only 21 kcal/m²/yr. This energy loss limits the number of trophic levels in a food chain, usually to four or five levels.The complete question is
Only a small amount of the energy stored in food is available to the next organism in a food chain because
A.There are more producers than consumer in a food chain
B.There are fewer top consumers than producers in a food chain
C.Primary and secondary consumers compete for food
D.Most of the energy is used for life processes
Increasing the volume of air that reaches the alveoli and takes part in gas exchange will cause blood pH to:
Answer:
Increase
Explanation:
As CO2 enters the blood, most of it is converted to the carbonic acid in a reaction catalyzed by carbonic anhydrase. The carbonic acid dissociates into hydrogen ions and bicarbonate ions. As the H+ concentration increases, the blood pH decreases. Thus, the increased partial pressure of CO2 produces a more acidic environment. Increasing the volume of air that reaches the alveoli and takes part in gaseous exchange will increase the rate of removal of CO2 from the blood. The reduced CO2 levels in the blood would increase the blood pH.

The energy available to consumers determined by subtracting the energy used by plants from the total energy transformed by the process of photosynthesis. True or False
Answer:
True
Explanation:
during photosynthesis, plants store up energy as starch, it is this starch that is the energy available to herbivours. thus the energy available to herivours is the is energy left from the difference between total energy produced during photosynthesis and the energy used by plants for the process.
Answer: false
Explanation: The law of transformation of energy states that energy can neither be created nor destroyed but are transformed from one form to another. Plants are the producers. They trap solar energy from the sunlight and transforms it into chemical energy. This chemical energy is then utilized by consumers. Hence Solar energy =chemical energy

It is caused by the loss of normal rod function in retina, and loss their ability to response in the light. The outer part of retina is made up of more rods compare to cones, loss of peripheral area repeatedly results in night blindness.
The excretory system is responsible for moving toxic wastes, dissolved molecules, and excess heat. You would conclude that the excretory system contributes to:_________
Answer:
The excretory system is responsible for moving toxic wastes, dissolved molecules, and excess heat. You would conclude that the excretory system contributes to: Maintaining dynamic equilibrium in the body.
Explanation:
Living cells carry out chemical reactions, necessary for their functioning. These generate several substances, some of which are unwanted by-products and can give the organism if they accumulate. That is why they have developed special mechanisms for the elimination or excretion of these residual products. Excretion is the process by which the body removes metabolic wastes from the body. The excretory system is the set of organs and ducts of the body responsible for the elimination of waste products from the body. Among the substances that the human body must eliminate are carbon dioxide (from cellular respiration), bilirubin (which comes from the degradation of red blood cells), salts, water and urea (product of protein degradation ). These substances are processed in various organs. Excretion processes are important for homeostasis, that is, the maintenance of a constant internal environment (dynamic equilibrium) for body cells.
The excretory system is defined as the system of organs and tissues, which are involved in the function of excretion of toxic substances and reabsorption of essential nutrients and water.
The excretory system contributes to maintaining the dynamic equilibrium of the body.
Functions of excretory system are:The excretory system is a complex set of organs, tissues, and ducts to eliminate the toxic, waste, and unuseful products from the body. The products such as salts, water, bilirubin, and urea are excreted by the excretory system. It is also involved in releasing excess heat from the body.
Thus, the excretory system maintains the homeostasis of the body and the constant internal environment for the body cells.

The type of memory that is associated with the conscious recollection of previous experiences is referred to as ________ memory.
Answer:
Answer is explicit memory.
Explanation:
Explicit memory is one of the two types of long-term memory. The other type in implicit memory.
The explicit memory occur when you decide consciously to recollect or remember past or previous experience.
The Implicit is non-conscious recollection of previous experiences.
Explicit memory is the type of memory associated with the conscious recollection of previous experiences, such as episodic and semantic memories, distinguishing it from implicit memory that does not require conscious effort.
The type of memory that is associated with the conscious recollection of previous experiences is referred to as explicit memory. This type of memory includes memories that are intentionally recollected and typically consists of factual information such as previous experiences and concepts. There are two main types of explicit memory: episodic and semantic. Episodic memory refers to firsthand experiences we have had, like recollections of our high school graduation or a memorable dinner. On the other hand, semantic memory involves our knowledge of facts and concepts about the world, such as the understanding that the absolute value of -90 is greater than the absolute value of 9.
It is important to distinguish explicit memory from implicit memory. Whereas explicit memory requires conscious effort to recall previous experiences, implicit memory does not involve such conscious recollection and pertains to the retention of skills and habits. Patients with neurological damage that affects explicit memory, for instance, may still display implicit memory when demonstrating learned actions without a conscious memory of the learning experience.

Do the new data support the hypothesis that the parasite switched surface glycoproteins once the host immune system responded to the original glycoprotein?
Answer:
It depends on your data, BUT read explanation
Explanation:
There are two ways to see this question and both are related to the fact that there is a parasite that could change surface glycoproteins at its will. Now, the question is when, and that when is once the host immune system attack it. If you perform an experiment where you have surface glycoproteins of the parasite without any disturb, a situation where the parasite has to respond and a control for this situation ( in this case an attack of the immune system), and the surface glycoproteins after the parasite deals with the situation you can infer some things.
First, if you compare the second surface glycoproteins in both experiments (with immune system attack and with control situation), and you see they are very different yo could say the immune system could have some influence on surface glycoproteins.
Now, you cannot infer completely, you have to see if there is a difference between the initial state of the surface glycoproteins and the final state of them after the immune system attack. There you can see if there is any difference on surface glycoproteins.
BUT you have to see if the comparison between the initial state of the surface glycoproteins and the final state of them after the control situation also changes and in what matter to see if is really the immune system the only one who affects surface glycoproteins.
