Answer:
nucleus
The function of the nucleus is to regulate gene expression, including controlling which proteins the cell makes. In addition to DNA, the nucleus contains a thick liquid called nucleoplasm that is similar in composition to the cytosol found in the cytoplasm outside the nucleus
Explanation:
Answer:
Explanation:
A gene pool typically has two or more alleles for a given trait. Homozygous lethal traits can be carried by heterozygous individuals and thus remain in a gene pool. Relative Frequency is the number of times an allele occurs in a gene pool compared with the number of times other alleles occur.
I’m pretty sure this is right
The thermosphere is the layer in the Earths atmosphere directly above the mesosphere and below the exosphere. Within the layer of atmosphere, ultraviolet radiation causes photoionization of molecules creating ions the thermosphere continues the larger part of the Ionosphere.
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!
