Answer:
Okay let me break this down, so you have a pure red and pure white feathered chicken meaning that the chickens have homologous alleles. Overtime, as you breed the two you may get multicolored chickens but they can carry the recessive white feathers alleles (FWFW) meaning that they can still produce all white chickens and they can continuously do that over generations. Selective breeding may be negative because you may not get the desired result, you could breed for the wrong traits, other characteristics are lost and the resulting population is very similar. Less genetic variation can cause the chickens to not be resistant to problems like diseases and could fall ill.

Hi there!
This is because on Earth the gravitation pull is a lot stronger than on the moon. Weight is based off gravity while it’s MASS that shows how much space you actually take up.

Answer:
Functions of epithelial cells include secretion, selective absorption, protection, transcellular transport, and sensing.
Explanation:
Epithelial layers contain no blood vessels, so they must receive nourishment via diffusion of substances from the underlying connective tissue, through the basement membrane.
