Answer:
Option B, The controls on cell growth and divisions can be turned on and off
Explanation:
There are signal proteins that control and regulate the cell growth and division process. For instance, mitogens help in removing the negative controls which would otherwise have blocked the cell cycle progression. Then there are growth factors that synthesize proteins and hence stimulate cell growth. Also there are some survival factors that suppress the apoptosis. Based on these three factors the cell division and growth can be turned on or off.
Hence, option B is correct

c. sarcopenia
Explanation:
Muscle cells are involved in movements. Skeletal muscles are one of the types of muscles present in the body that are responsible for voluntary movements. As the person ages, the skeletal muscles of the body experience a progressive reduction of their mass. The systemic reduction in muscle mass also adversely affects their functions. The condition is called sarcopenia. Significantly reduced muscle mass results in several functional disabilities. Sarcopenia is the reason that the person with increasing age is more likely to be affected with muscular disorders.
