Question

A skin cell divides by mitosis once every day to produce new skin cells. how many days it would take to produce 16 skin cells from one skin cell?

Answer 1

It would take `4` days.

Explanation:

You can count out the days:

You can use a power of `2` to solve this:

`2^4=16`.

Or count out the days:

After `1` day, you have `2` cells.
After `2` days, you have `4` cells.
After `3` days, you have `8` cells.
After `4` days, you have `color(red)(16)` cells.
