So if I were to have 10 rabbits, and 7 of them didn't have as greater hearing as the other 3, the other 7 could get killed from being preyed on. The remaining 3 would be the bottleneck population?

I must say, you really know a lot about Biology, are you a professor or teacher? If I asked you to descrive a cell membrane, would you just say a double layer of lipids containing proteins? I'm studying hard before exams.

Is that why a cell can only grow to a certain size? Because the membrane would be too stretched and break?

If a mutation were to affect a population over time would that become and evolutionary change?

Thanks, as an implication, I could talk about how it could affect future generations too.

Thanks for your help! I'm loving this website! :)
