I believe the thyroid controls most, if not all of those things. (Again, I'm not entirely sure.)
<span>the large population becomes smaller.
also, bottleneck is when a large population quickly shrinks. the effects of genetic drift becomes much stronger.
e.g: seals
alleles can be lost during bottleneck and the number of alleles left can shift dramatically in just a few generations.</span>
I'd say create a compost bin. Hopefully this was what you were looking for.
They all have these traits: <span>Cellular organization, Reproduction, Metabolism, Homeostasis, Heredity, Response to stimuli, Growth and development, and <span>Adaptation through evolution.</span></span>
