Answer:
Assuming that 235 kcal energy from Chicken A La King comes from carbohydrates, fats, and proteins only, we can determine the mass of protein in the serving by knowing the amount of energy the protein provides. It is necessary to know how much energy each gram of carbohydrates, proteins, and fats provide.
1 gram of Carbohydrate = 4 kcal
1 gram of fat = 9 kcal
1 gram of protein = 4 kcal
We need to determine the energy contributed by carbohydrates and fats.
For Carbohydrates:
After knowing the energy from carbohydrates and fats, we can determine the energy from protein
We can now determine the mass of proteins in g
The answer is 20.75 grams.

Explanation:
Telomerase is an enzyme that is produced in the body. It prevents the shortening of the length of telomeres.
Telomerase is not usually activated in the cells of the body but you can find them in cells responsible for the production of sperm and egg in humans.
In others for cells to keep living , the length of the telomere must be maintained and this is one of the reasons why cancer cells thrives in the body and keeps dividing and spreading because telomeres are always present in cells that keep dividing.
Telomere are very essential to growth of cancerous cells. Shortening the length of telomeres is not enough to kill cancerous cells as we have cancer cells with short length ( bone, kidney, prostate cancer). We have to combine other methods of cancer treatment to be able to eradicate the cancerous cells from the body.
Bone marrow is a body tissue where the cells are always dividing because this is crucial and essential for the replacement of old cells. In the bone marrow we can find enzyme telomerase present hence, this makes the bone marrow an exception.
Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results
