An example of selective breeding is breeding cattle to produce better meat.
After translation of the polypeptide
in the ribosome, the polypeptide enters the cisternae of the rough endoplasmic reticulum.
Here, the folding of the polypeptide begins with the aid of chaperons proteins.
At the end of the RER, vesicles with the completely folded protein bud off and enters
the Golgi apparatus where the proteins are transported to its destination.

Answer: crossing over allows for genetic variation
Explanation:
crossing over is the exchange of genes between two chromosomes which ends up resulting in non-identical chromatids that comprise the genetic material of gametes (sperm and eggs).
Basically crossing over makes the chromatids that are held together by a centromere, no longer identical to eachother which creates genetic variation.
Answer:
dilation of vessels and sweating
Explanation:
The vast blood supply of the skin aids in temperature regulation: dilated vessels enable heat to escape, while constricted vessels retain heat. The blood supply of the skin regulates body temperature. The skin aids in the maintenance of homeostasis. Humidity has an effect on thermoregulation because it reduces perspiration evaporation and, as a result, heat loss.
