Cells in the body experience changes with aging. as cells age they tend to become and as the body ages it tends to have a) larger; more cells dividing b) smaller; more cells dividing c) larger; fewer cells dividing d) smaller; fewer cells dividing

option D, smaller; fewer cells dividing

Explanation:

With aging a cell's performance slows down and after a certain period of time it dies. In this way several cell die in an aging person , thereby making an organ less functional.

The number of living and functional cells in testes, ovaries, liver, and kidneys decreases markedly with aging.

As a cell dies, it shrinks and reduces in size thereby expelling liquid out of it.

Also the rate of formation of new cells reduces with progressing age.

Therefore, as a person becomes old the cell reduces their size and hence die. Also the cell division process becomes slow

Option D is correct

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.
