Answer:
Explained
Explanation:
Eight prophase cells, one metaphase cell,three anaphase cells, and four telophase cells. It results in 8 + 1+ 3 + 4 = 16 cells.This indicates that the remaining cells of 32-16 = 16 were in interphase.This means the cells spend the maximum amount of time in interphase.This time is equal to half the total cells.
So, if it's a 24-hour process,the interphase should spend 12 hours.
Six hours of prophase, 45 minutes in metaphase and 2 hour, 15 minutes in anaphase, and 3 hours in telophase.
