<span>D. Autonomic nervous system
It is called autonomic because it works on its own and it regulates organs functioning which is a thing that happens involuntarily. It regulates heart beats for example and it's not something that you do voluntarily since the heart beats regardless of you.

Organisms that inhabit intertidal zones must be able to tolerate radical changes in temperature, salinity, and moisture and also be able to withstand wave shock. Intertidal zone is the coastal area alternately exposed and submerged by tides. Tide pool animals and plants are well adapted to the intertidal zones. Some adaptations include; the ochre sea star can tolerate a longer time period exposed to air than many other sea stars. They regularly withstand up to eight hours of exposure during low tides.
So cells have what are called telomeres. These act as a dividing limit. The point of limiting the amount of times a cell can divide and reproduce is to help prevent cancer. Cancer is simply uncontrolled division of unhealthy cells. By limiting cell division one can help prevent cancer.
