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!
Answer:
heterologous
Explanation:
Recombination occurs between homologous regions between chromosomes.
Although sex chromosomes come from autosomal chromosomes and were once homologous, they have evolved distinctly casuing low homology between them. Currently sex chromosomes are heterologous and differ substantially in composition. In fact, recombination between sex chromosomes only occurs in a small pseudoautosomal region that is still homologous.
