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.
Answer 1: Difference b/w wet and dry earwax genes is due to switch of a single DNA unit i.e. single nucleotide polymorphism.
Answer 2: Earwax is important in many ways mainly it is a biological flypaper as it prevents dust and insects from entering the ear.
