Tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail
All of these represent something called "competition and predation", in which the species competes for strength, or when one species coordinates attacks against a prey species, or when one species hunts another.
When a person is hot, the blood vessels in the dermis dilates, in order to maintain the homeostasis. When the temperature is increased, it becomes necessary to lose the body heat. This increased heat is lost by rushing the blood to the vessels present in the dermis layer. These blood vessels dilates so that more blood can flow inside these and the heat can be lost.
hence, the blank can be filled with 'dilate'.
Answer: B. It sped up evolutionary change by increasing genetic variation.
Explanation:
Evolution works when organisms with genes that are better suited to the environment pass on their genes to future generations.
Sexual reproduction sped up this process because it allowed for genetic variation as genes from the two mates would be passed on the next generation instead of one organism as had been the case with asexual production.
With genes from both mates mixing up and going into the next generation, more genetic variations were produced which allowed for the organisms to better adapt to the environment.
