In determining species, it is best to differentiate in terms of the population that is being adapted in which, a certain niche. So, if it has a small gene pool, and the different species will be interbreeding each other with a much genetic variability in gene pool, it would most likely cause a less adaptation. The niche will be having a less adaptation if too much genetic variability will occur.
Answer:
high in protein i believe.
Explanation:
Blood flows out of a cut so as to maintain the body pressure, this occurs because pressure inside the human body tends to be greater than the external environment pressure. Since blood flows from high pressure to low pressure, it thus runs off a cut
Answer:
A & C
Explanation:
Aorta is the biggest artery and channels pumped blood from the left ventricle of the heart to tissues. It, therefore, needs to bear the greatest burden of blood pressure because the left ventricle is thicker than the right ventricle and pumps blood with high pressure so that it reached the tissues with the right hydrostatic pressure to allow blood plasma pass through the capillaries walls into tissue fluid.
The walls of the aorta need to be thick enough and elastic to bear the pressure. This is why the <em>tunica media</em> is thickest it aorta because these elastic fibers provide strength and elasticity to prevent rupturing and smooth muscle cells contract and relax in regulation of this pressure to maintain the right pulse.
<span>Catfish and carp require less oxygen than trout. The mouth of a river usually has less oxygen and the area closer to the source has more oxygen, so since catfish and trout require more oxygen they typically are found at the source.</span>
