"Sex Cells" or "haploids" are needed in order to add variation in DNA. If there was no "haploids" (which are just cells with 23 Chromosomes), then the female would not need the male for reproduction, basically meaning birth of an identical twin to the mother. The two haploids, the female's ova (Egg) and male's sperm meet, creating a zygote, or a fertilized egg.
This makes sure there is "immediate variation", and it isn't just ten generations of the same "Bob"!
Answer:
Explanation:
The cell membrane, also called the plasma membrane, has the following characteristics:-
It is present as the outermost layer in animal cells and lies below the cell wall in plant cells.
The cell membrane surrounds the cytoplasm of living cells, physically separating the intracellular components from the extracellular environment.
The cell membrane is semi-permeable, ie, it allows some substances to pass through it and does not allow others.
It is thin, flexible and a living membrane, which consists of a lipid bilayer with embedded proteins/
The cell membrane has large content of proteins, typically around 50% of membrane volume. These proteins are important for cell because they are responsible for various biological activities.

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.
