When, during an organism’s lifetime, would you expect to observe lots of cells undergoing mitosis? when would you expect to see very few cells undergoing mitosis?

A) During youthful age, lots of cells undergo mitosis

B) During old age, only few cells undergo mitosis

Explanation:

Mitosis is the division of a cell nucleus in which the genome is copied and separated into two identical halves. It is one of the two types of cell division.

Whenever, a cell undergoes mitosis , there is a slight shortening of the telomeres on the ends of each chromosome. As soon as this shortened telomere reaches a certain length cell division ceases. Then the cell is said to be aged and approaching death phase. These kind of cells is found in adult humans.

On the other hand, cell division occurs faster in babies, as they need to grow to adult size, and that means that their cells must divide faster than adult cells. In fact, depending on the cell type, the infant cells divide as much as twice as quickly as the adult cells.

its like this, "if i give a plant an unlimited amount of sunlight,then the plant will grow to its largest possible size."

hope it let me know if it does or doesn't =^-^=

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
