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!

Option A, Fixed quota models are risky because slight miscalculations can result in fish population extinction
Explanation:
Some of the major drawbacks of modelling fishing are as follows –
a) The fixed quota model is very risky as a miniscule change in attributes can result into extinction of fish.
b) On the other hand fixed effort harvesting can decrease the risk of fish population extinction
Hence, option A is correct
The statements that are true of logistic growth are A) as the population becomes larger, it grows more slowly, and B) when the population reaches carrying capacity, it stops growing.
