Two turns of Kreb's cycle are needed for one molecule of glucose.
The Kreb's CycleThe cycle represents part of the process of breaking down glucose to extract the locked energy in the form of ATP.
Each glucose molecule to be broken down first undergo glycolysis at the end of which 2 pyruvate molecules are produced.
Each turn of the Kreb's cycle requires a molecule of pyruvate. Thus, the two pyruvates molecules generated from single glucose will require 2 turns of Kreb's cycle.

What happens when the body fails to take up excess glucose from the blood a. The excess glucose binds to working proteins, rendering them nonfunctional. b. The excess glucose is metabolized to produce energy for physical activities. c. The excess glucose retains water in the body to prevent dehydration. d. The excess glucose from the blood gets stored in the adipocytes. e. The excess glucose gets converted into useful alcohols.
Explanation:The excess glucose gets converted into useful alcohols.
When the body is unable to take up excess glucose from the blood then at time the fats from the blood gets stored in fats storing cells called as adipocytes. The excess glucose gets converted into useful alcohols. Last option is correct.
What are adipocytes ?These are the cells that store fats in the human body are called as adipocytes. These are the main energy storing cells.
The excess glucose gets converted into useful alcohols.
At this situation glucose is provided by the the carbohydrates where the glucose is the stored compound in the form of glycogen.

What would happen if you changed the temperature and ph around the enzyme?
However, extremely high temperatures can cause an enzyme to lose its shape (denature) and stop working. pH: Each enzyme has an optimum pH range. Changing the pH outside of this range will slow enzyme activity. Extreme pH values can cause enzymes to denature.
If the temperature and pH around an enzyme is changed, the enzyme would likely denature. Details about enzymes can be found below.
What is an enzyme?Enzymes are biological catalyst that regulates the rate of biochemical reactions in living cells.
Enzymes function at a particular temperature and pH and can easily get denatured i.e. alter its original form.

what is potential energy
Answer:
The energy of a body or a system with respect to the position of the body or the arrangement of the particles of the system.
Explanation:
Energy is a delicate notion that is extremely difficult to master. Energy is sometimes described as the ability to accomplish labor, that is, to push anything against a force. That isn't completely correct, since due to the Second Law of Thermodynamics and the fact that much energy is merely mass, there is a lot of energy that isn't accessible to do any work. We're on somewhat better ground with potential energy. When we say there is potential energy, we mean that there is something in a system that, if permitted to alter, has the capacity to accomplish work. Saying that there is potential energy is a form of abbreviation. Consider gravitational potential energy. If two masses are separated by a distance, we might let them fall together and accomplish some work, perhaps by pulling a rope tied to a wheel or whatever. We have the energy to get there. Of course, it is a fraction of the overall energy in the system. When we get to notions like that, we must count a lot more. Nonetheless, some cosmological models require a type of negative gravitational potential energy to make total energy conservation work. According to such views, nearly all of the universe's mass condensed out of the vacuum to offset the negative energy associated with the inflationary epoch. As a result, the universe's total energy is zero. It is not the sole hypothesis, but it is useful in that it answers the issue of why there is something rather than nothing. It would imply that there is nothing completely, but it is unevenly dispersed. One of the two major forms of energy is potential energy. Potential energy is the amount of energy that an object can hold. It is the power that a thing has while it is not in motion. The potential energy of a moving item increases as it slows down. The object's capacity strength reduces as it accelerates. Potential energy is the electricity that occurs as a result of the relative locations (configurations) of the components in a physical machine. This energy form has the capacity to modify the state of other things around it, such as the configuration or movement. Potential energy encompasses a wide range of energy kinds.

What molecule is the final electron acceptor in the Electron Transport Chain?
The final electron-accepting molecule in the electron transport chain is oxygen.
Role of oxygen in the electron transport chainOxygen mainly acts as an electron acceptor in the electron transport chain. More specifically, it acts as the final electron acceptor to ensure that oxidative phosphorylation takes place.
Without this final electron acceptor, the electron transport chain will not be able to complete the cycle, and energy molecules in the form of ATP will not be formed.

The brain and central nervous system shrink as we age.
What happens to the brain when we age?The brain is one of the most important organs in our body because all the nerve signals are produced there for our body to function.
In the brain we find nerve connections through neurons. A particular aspect of them is that during childhood and adolescence they multiply as we learn new things.
However, once we reach the stage of old age, these nerve connections deteriorate and are reduced, therefore, the size of the brain and the central nervous system decreases.

C. The comparison of species based on the presence or absence of
ancestral traits
D. The comparison of species based on common physical

The comparison of species based on common physical characteristics Thus, the correct option is D.
What is cladistics?Cladistics is a method of biological taxonomy that organizes taxa in a branching hierarchy so that all members of a given taxon share the same ancestors and defines taxa uniquely by shared traits not present in ancestral groupings.
Clades, which are collections of organisms made up of an ancestor species and its offspring, are also identified through cladistics.
A cladogram only displays one probable phylogeny for a collection of organisms. It can shed light on the process of evolution. A cladogram should not be viewed as a representation of genuine evolutionary processes, though. It may or may not depict what actually occurred. It merely illustrates what might have occurred.
