Answer: First, p53 triggers production of Cdk inhibitor proteins, pausing the cell cycle in G1 to allow time for repairs. ... In cancer cells, p53 is often missing, nonfunctional, or less active than normal. For example, many cancerous tumors have a mutant form of p53 that can no longer bind DNA.
Explanation:
<span>S phase is the duplication of the cells genetic information, if this did not occur, when the cell divides into two cells, there would be no copy of this genetic information given to 1 out of the 2 cells.

The smaller the surface area to volume ratio, The larger the Cell will become.
And the larger the cell, The ability to take in and use nutrients from its environment tend to be Decreased.
This happens because the large cells wouldn't have enough material fast enough to accommodate/fulfill its large volume.
Answer:
b. the interaction of food availability and predation intensity
Explanation:
The complete question is as follows:
What best explains snowshoe hare and lynx population cycles?
a. the seasonal trends in food availability
b. the interaction of food availability and predation intensity
c. natural variation in the number of lynxes born
d. the population density of snowshoe hares
- The population of snowshoe hare and lynx are closely linked to each other and this is because the primary food of lynx is the snowshoe hare.
- When the number of hares is more lynx eat more of hares and less of other food and when the number of hares is scarce, lynx eat alternate food.
- However, in the scarcity of hares, the other foods do not provide lynx with their nutritional needs and therefore, many of them leave their home grounds.
- Therefore, when the hare number declines lynx number also declines.
- The population cycle spans over 8-11 years.
- The number of hares decreases at the end of the cycle and so does the number of lynx.
- However, at the beginning when the number of the hare is more, they starve due to competition and are easily caught by the lynx and thus, the lynx population also increases.
The answer is ribose.
mRNA is actually messenger ribonucleic acid. As any other RNA (ribonucleic acid) it consists of a phosphate group, sugar ribose, and nucleobases (adenine, uracil, cytosine, guanine). So, it is called RIBOnucleic acid because it consists of sugar RIBOSE.
Take for example DNA - deoxyribonucleic acid. It is called DEOXYRIBOnucleic acid because it consists of sugar DEOXYRIBOSE.
