Answer:
Stabilizing Variation.
Explanation:
This is the type of variation that occurs when genetic diversity decreases as the population of organism in a particular population based on a specific trait.
Organisms with varied or specific traits within the population are selected against by the selection pressure, with little chances of reproduction, while organisms in between, ( with least variation of this particular traits) which are within the narrow range, survive to reproduce.Thus, this gives rise to narrow population of these particular organisms,(stabilizing variation) which are therefore naturally selected.
Therefore, the variation of the organisms in this population is kept close to the centre of the same mean value.
The answer is A (the sun)
Answer:
Cell membranes: Lipids, protein and carbydrates
Diffusion is the movement of materials across a membrane of greater concentration gradient to lower concentration gradient.
Osmosis is the movement of a solvent (usually water) across a selectively permeable membrane.
Active transport is the movement of materials against concentration gradient at the expense of energy.
Answer:
Hydrophilic
Explanation:
a philia is an attraction to something.
