Question

We would expect which one of these healthy individuals to have the highest amount of mitotic cell division happening?

Select one:

a. A 45 year old male human

b. A geriatric mammal of any species

c. A 75 year old woman

d. A middle aged goose

e. Any newborn animal

f. Any female animal

Answer 1

Mitotic cell division occurs to grow much faster and replace old cell and form new cells. Many cells grow initially at faster rate but after some time get arrested at maturity as we see in plants. So at elder or old age of life , some cells are not capable of dividing and hence rate of mitotic cell division becomes slow.

At initial stage of life like new born animal have highest rate of mitotic cell division for growth.All cells in a new born is capable of dividing.

Hence answer is option "e".
