Answer:
c. There is uncontrolled cell division.
Explanation:
There is uncontrolled cell division that result in the improper functioning of a checkpoint protein in a cancer cell because checkpoint protein monitors and control the the process of cell cycle. If mutation occurs in this checkpoint protein, the cycle is no longer in control which leads to the uncontrolled cell division and we also know that cancer is a disease which occurs due to uncontrolled division of the cell.
OK First we need to eliminate 2 answers which would be A and C
that leaves B and D
I believe the correct answer is D
because it explores all of the relationships of the food web as to just one.
hope this helps

Epithelial cells also line the inside of your throat, intestines, blood vessels, and all your organs. They are a barrier between the inside and outside of your body and are often the first place that is attacked by viruses as they begin their invasion deeper into the body.
Explanation:
Epithelial tissue covers the outside of the body and lines organs, vessels (blood and lymph), and cavities. Epithelial cells form the thin layer of cells known as the endothelium, which is contiguous with the inner tissue lining of organs such as the brain, lungs, skin, and heart.
