Answer:
C). viscosity increases with increasing length of the blood
Explanation:
Systemic vascular resistance (SVR) refers to the resistance to blood flow offered by all of the systemic vasculature, excluding the pulmonary vasculature. This is sometimes referred as total peripheral resistance (TPR).
Some factors that decrease blood flow and increase resistance include increased viscosity of the blood, increased length of the blood vessel and decreased radius of the blood vessel. Blood vessels - and in particular, the more muscular arteries - are often the source of resistance.
What determines resistance are:
1. Resistance is proportional to LENGTH (L) of the tube (blood vessel)
-Resistance INCREASES as length increases
2. Resistance is proportional to VISCOSITY, or thickness, of the fluid (blood)
-Resistance INCREASES as viscosity increases
3. Resistance is inversely proportional to tube RADIUS to the fourth power
4. Resistance DECREASES as radius increases
Think it’s is a sorry if I get it wrong

Answer:
disruptive/diversifying selection
Explanation:
Disruptive (also known as diversifying) selection is a type of natural selection where extreme phenotypic values are more favored rather than intermediate phenotypes. The disruptive selection favors the survivance and reproduction of organisms with extreme phenotypic traits, and in turn impairs the reproduction of organisms with intermediate traits, thereby changing the allele frequencies in the population in order to favor extreme values. An example of disruptive selection is the beak size of Galapagos finches, where extreme phenotypes of this trait have shown to be adaptive according to the type of food found in each island.
