Answer:
Aerobic: Processes Oxygen, Carbon Dioxide by-product
Anaerobic: Processes Carbon Dioxide, Fermentation
Both: Produces ATP, Takes place in cells
Explanation:
Aerobic Process: Oxygen, Carbon Dioxide by-product
Anaerobic Process: Carbon Dioxide, Fermentation
Both: Produces ATP, Takes place in cells
What is respiration ?Respiration is a metabolic process in which an organism's living cells use oxygen to obtain energy (in the form of ATP) and release carbon dioxide as a byproduct of the oxidation of complex organic substances.
Anaerobic respiration occurs when there is no oxygen present, whereas aerobic respiration occurs when there is oxygen. Alcohol is produced by anaerobic respiration, whereas carbon dioxide and water are the byproducts of aerobic respiration. Compared to anaerobic respiration, aerobic respiration produces more energy.
Thus, respiration is a vital process of the body.

Shortly after ingesting a big plate of carbohydrate-rich pasta, you measure your blood's hormone levels. What results would you expect, compared to before the meal
Answer:
blood hormone level will increase
Explanation:
since once food reach the stomach it will trigger different hormone process that cause release of enzymes required to digest carbohydrate
After ingesting a plate of pasta, which is rich in carbohydrates, the levels of insulin increases and glucagon decreases in the blood.
The working of insulin and glucagon:The hormone insulin and glucagon work in a negative feedback loop. At the time of digestion, the foods, which comprise carbohydrates are transformed into glucose. The majority of this glucose is sent to the bloodstream, resulting the elevation of blood glucose levels.
This enhancement in the levels of glucose in the blood signals the pancreas to generate insulin, and reduce the levels of glucagon in the blood. After some hours, glucagon works to counterbalance the activities of insulin.
After five to six hours, the levels of glucose in the blood decreases due to the activity of insulin, this instigates the pancreas to generate glucagon.
Thus, after eating carbohydrate rich food, the levels of insulin increases in the blood and glucagon decreases.

What happens as electrons move along the chain of molecules known as the electron transport chain?
Answer:
In the electron transport chain, electrons are passed from one molecule to another, and energy released in these electron transfers is used to form an electrochemical gradient. In chemiosmosis, the energy stored in the gradient is used to make ATP.

Claim: The optimum pH environment for catalase is approximately pH 7.0 and thus has the highest activity in a neutral pH environment. If the solution is too acidic or too basic the catalase is inactive and no longer functions as an enzyme.
Answer:
In the case of catalase, the optimum pH is approximately pH 7.0. That is, catalase works best at a neutral pH. If the solution is too acidic (low pH value) or too basic (high pH value) the catalase is inactive and no longer functions as an enzyme.

Very large, massive stars burn their fuel much ___________ than smaller stars.
Answer:
Very large, massive stars burn their fuel much faster than smaller stars. Their main sequence may last only a few hundred thousand years. Smaller stars will live on for billions of years because they burn their fuel much more slowly. Eventually, the star's fuel will begin to run out.

Suppose scientists determine that a set of genes is significantly more prevalent in murderers than in the population at large. Would that mean that murderers are not at fault for what they do? Why or why not?
Answer:
No
Explanation:
That a gene is common to all murderers in the population does not mean that murderers are not at fault for their crimes.
Having a gene that correlates with murder just gives one a genetic tendency but the environment and personal choice still have to influence the decision to commit the crime. In other words, one might have the genetic tendency to commit murder but still has to be environmentally enabled and the ability to choose to either do it or otherwise. Nature, nurture, and personal choice would have to synergistically work together for the phenotypic expression of such a gene.

What is the importance of the amniotic egg?
Answer:
The amniotic egg was an evolutionary invention that allowed the first reptiles to colonize dry land more than 300 million years ago. Fishes and amphibians must lay their eggs in water and therefore cannot live far from water. But thanks to the amniotic egg, reptiles can lay their eggs nearly anywhere on dry land.

Would a cell that did not undergo cytokinesis be able to function properly? Explain.
Answer:
If cytokinesis wouldn't really occur, the cytoplasm would not be broken and two similar daughter cells would not function as a result. Therefore a cell should not be divided into two separate cells to stay at rest.
Explanation:
Cytokinesis, which is the final step of mitosis, is split into two isolated, equivalent daughter-cells by the material.
