Ok, I'm not 100% sure this is correct, given the context of the situation, but basically, the cell membrane helps the cell maintain homeostasis by keeping what needs to be in in & what needs to be out out. If it weren't for the cell membrane having the structure it does, all kinds of things could get into the cell & completely kill it from filling it with too much stuff, or the wrong things could get in (say, things with a really odd pH) & damage it badly. Or, it could let things get out extremely easily, such as enzymes and ions the cell needs to function properly.
Hope this helps!
A simple google search of that exact answer will show that "In a human egg or sperm, there are 23<span> chromosomes, one of which is an X or Y. The number of chromosomes is reduced from 46 to 23 during the process of meiosis. Fertilization of the egg by the sperm restores the diploid number of 46 chromosomes."</span>
Antarctica would be the answer
Answer:
BBDd is 40%
BBDD is 20%
bBDD is 20%
bBDd is 20%
Explanation:
If we apply the punnet square technique to the given genotypes in the question, we can find the genotypic ratios of the offspring. For the genotypes BbDD and BBDd, the genotypes of the offspring can be as follows:
BBDD, bBDD, bBDd, BBDd and BBDd.
BBDd is 40%
BBDD is 20%
bBDD is 20%
bBDd is 20%
I hope this answer helps.
