The rate at which blood flows through the human body can change in response to multiple factors. Which statement describes one o

f these factors and the effect it has on blood flow?
A. The narrowing of blood vessels increases pressure and leads to faster blood flow

B. High blood viscosity increases the resistance in the blood vessels and leads to faster blood flow.

C. Low blood pH decreases the rate of diffusion through the blood vessels and leads to slower blood flow.

D. The changing of the shape of red blood cells to a crescent shape decreases resistance and leads to faster blood flow.

Explain why this is the correct answer and why the other ones are wrong:

Answer:

B

viscosity of blood causes an increased resistance in the blood vessels and

leads to slow blood flow

blood cells. Thick blood travels through blood vessels at a slower rate than thin blood

maria [59]
The correct genotypes of the parents are ggrr for yellow pods with wrinkled seeds and GgRr for <span>heterozygous for green pods with round seeds.
If the heterozygous individuals for both traits express have green pods and round seeds that tells us that these traits are dominant.
In the gross presented below, you can see that the offspring will have 4 different genotypes, all present in an equal percentage:
</span><span>gGrR 25% 
</span><span>gGrr  </span>25% 
<span>ggrR 25%
</span><span>ggrr 25%</span>

What makes nekton swimming abilities different from plankton and benthos
Nitella [24]

Answer:

The nektonic organisms are those marine organisms that are found in almost every depth. These can move freely from one place to another in the ocean body due to its ability to swim. For example, Turtles, sharks, Fishes, and dolphins.

The planktonic organisms are passive swimmers, as they can move along with the ocean currents and are mostly found in the upper portion of the ocean body. For example, Diatoms and Rotifers.

The benthos is the bottom-dwelling organisms that cannot swim. For example, Bivalves, Corals and Sponges.

The nektonic organisms are different from the planktons and the benthos because the nektons can easily swim. They are constructed with such body parts that allow them to swim and migrate from one region to another region within the ocean water body. Whereas the planktons and the benthos cannot migrate easily and are considered as sessile organisms.
