Answer and Explanation:
Dormancy is a period in an organism´s biological cycle in which its growth, development, and physic activity gets suspended for a period of time. This causes a drastic reduction in metabolic activity, allowing the organism to conserve its energy. Dormancy is closely related to environmental conditions, and it is considered to be an adaptation mechanism by which organisms respond to extreme conditions.
Hibernation belongs to this dormancy process, in which animals progressively decrease their metabolic rates and their body temperature is held a few degrees over the ambient temperature. During hibernation, all functions are reduced: cardiac rime, respiration, renal function, and etcetera.
Before hibernating, bears eat a huge amount of food because this energy is what will keep them alive while hibernating. This action is known as hyperphagia, and while doing it, bears accumulate fate in their tissues. As these animals need to maintain the energy balance and metabolic health, they make use of these reserves. The nutrients excess will turn into triglycerides, that the animal will use to store in the fatty cells. There are several elements involved in the process, such as sugar, amino acids, glycerol, among others.
The fatty acid catabolism is the predominant reaction that occurring in this bear. Option C is correct.
Hibernation:
In this condition, animals decrease their metabolic rates and their body temperature is increased a few degrees over the ambient temperature. During hibernation, the heart rate, respiration and renal function is reduced.
The bears hibernate in the winter because of the lake of food outside. Hibernation help them to stay alive even in the no food is available for few months.
Before hibernation, bears eat a huge amount of food and store a lot of fat this fat provide a constant supply of energy during hibernation.
Therefore, the fatty acid catabolism, provide the energy during hibernation of bears.

A science club has 16 members. How many ways can a president, a vice president, and a treasurer be selected from the members?
A 96
B. 560
OC 1,120
D. 3,360
Answer:
The answer would be D. 3,360
Explanation:
The solution is found by multiplying 16 times 15 times 14. The club has 16 members and after one role (president) is filled, there are 15 left to fill the next (vice). The same goes for the next role (treasurer). So 16 is multiplied with 15, then 14. This is more of a math question that biology btw.

Why is a supply of oxygen important for muscle contraction?
Answer:
For muscle contraction to take place oxygen is needed. ... Oxygen allows the body to convert glucose into ATP more efficiently without creating a waste product.
Cellular respiration is the process in which your muscles use oxygen to produce ATP energy. ... Whether you're exercising or not, the oxygen in your body is used to break down glucose and create the fuel for your muscles called ATP

Explain the concept of functional specialisation and describe two brain areas that exhibit functional specificity
Answer:
Functional specialisation explains how the two cerebral hemispheres are specialized in different types of mental activity.
Explanation:
The nervous systems of all animals have in common a number of basic functions, the most notable of which are control of movement and analysis of sensation. What sets the human brain apart is the variety of more specialized activities it is capable of learning and the integration and control of the different functions. In 90% of the population the left cerebral hemisphere specializes or controls the ability to speak and write, and the ability to understand spoken and written language. In the remaining 10%, the right hemisphere or both hemispheres dominate spoken or written language. The right cerebral hemisphere perceives tactile stimuli and spatial vision relationships better than the left hemisphere. Another area, the posterior-parietal lobe is related to the tactile abilities, it is particularly involved in the abilities to name and point out the parts of the body, one's own and of others, as well as in the abilities to name, distinguish, recognize or draw the fingers of the hand. The parietal lobe is particularly involved in perceptual accuracy in locating stimuli, in estimating line orientation (parietal-frontal lobe) and in the ability to estimate the number of stimuli presented in the central visual field.

An unfertilized egg cell has six chromosomes. After fertilization, how many chromosomes should the zygote have?
Answer:
12 chromosomes, because the basic (haploid) number of chromosomes is 6 (n: 6)
Explanation:
The unfertilized egg contains a basic (haploid) number of chromosomes (n), being in this case 6. In humans, for example, the gamete haploid cells have a basic n content of 23 chromosomes, while in somatic cells this DNA amount is duplicated (2n), being therefore 46 chromosomes that are organized into 22 pairs of autosomal chromosomes and two sex chromosomes (X and Y).

Which of the following factors might cause checkpoint genes to interrupt cell division? Check all that apply. Neurological signals sent from fear responses in an organism tell the cell to stop. The cell's DNA has been damaged somehow. The cell's DNA was replicated incorrectly.
Answer:
Neurological signals sent from fear responses in an organism tell the cell to stop. The cell's DNA has been damaged somehow. The cell's DNA was replicated incorrectly.
Explanation:
All the three options given can cause checkpoint genes to interrupt cell division.
Checkpoint genes are transcription genes that control cell cycle and sense defects during cells processes like DNA replication, segregation e.t.c and create response till the defects is repaired in the DNA. The important of checkpoint is that it ensure enough nutrients are available to support for division, ensure that the DNA has not been damaged, ensure that cells DNA is copied correctly and make sure cells have enough RNA for their protein synthesis.
Checkpoints genes can interrupt cell division if the dna is damaged, Dna is copied incorrectly and neurological signal sent from fear responses in an organisms tell the cells to stop.
Answer:
The cells DNA has been damaged somehow and The cells DNA was replicated incorrectly
Explanation:
sometimes, these checkpoint genes are mutated or damaged and, thus, are unable to tell a damaged cell to stop dividing. When this occurs, the damaged cell gives rise to many damaged cells, which in turn create more damaged cells. These dividing cells form a NEOPLASM

In many popular fictional movies and books, future projections of the earth (and other fictional planets) show a world devoid of plants, with civilization bustling with activity throughout a worldwide city of skyscrapers hundreds of stories high. Based on your reading about photosynthesis and cellular respiration (Chapters 9 & 10), is this future world possible? Explain why it is or is not possible in terms of energy flow in the biosphere.
Explanation:
Cellular respiration and photosynthesis are two important physiological processes which formed the basis of life on Earth.
Evolutionary studies have shown that process of photosynthesis evolved earlier in organisms which led to the production of oxygen. This led to the formation of aerobic cellular respiration in organisms.
In the given, a world devoid of the plant is not possible because the plants perform the role of primary producers that is they utilize the available carbon dioxide and water and form the first stable energy molecule called glucose.
This glucose is broken down by the process of cellular respiration to further usable form. These two processes maintain the flow of energy on Earth.
Thus, without these two processes, the fictional world will not be possible.
