Answer:
It provides the cells with oxygen
Answer:
False
Explanation:
Humans all around the world has a body temperature similar, humans like all the mammals are endothermic (the body temperature is regulated for itself) animals, this means that our temperature doesn't change according to the climate.
Also the flow of the blood in our body changes according to the heart rate, while more bits per second our heart does, more blood flows in our extremities.
So it's false that human evolved in colder have more blood flowing into their extremities, and at a hotter temperature, than people living in warmer climates.
The bottleneck effect occurs when the majority of a population is destroyed due to natural disasters or human activity's. This reduces the size of the gene pool resulting in smaller variations from bird to bird. Gene mutation is the permanent change in the DNA or gene. Stabilizing selection occurs when genetic diversity decreases and the majority of the population stabilizes on a specific trait. The Founder effect occurs due to a smaller population leaving a larger population. This leaves the smaller population with smaller genetic variations. The correct answer is the Founder effect.
