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

Answers

Answer:

B

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

leads to slow blood flow

Explanation:

Viscosity refers to the thickness of blood. This thickness is caused by the number of red

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

Earth's core is the source of the energy that drives the movement of tectonic plates. Which two processes help transfer this energy outward to earth's crust?

Answers

Answer:The two processes are CONDUCTION and CONVECTION

Explanation:

The Energy produced in the Earth core is generated by  Sun, gravitational force , radioactive decay, and the  Earth' rotation, To maintain balance in the earth, The  processes of CONDUCTION and CONVECTION transfer energy (HEAT) to Earth's interior, which also helps the movement of  tectonic plates at a  constant rate.

Now, inside the earth mantle is made up of hot solid rock and because Conduction occurs more in solids, Its currents helps the continuous  transfer of heat energy  from the warmer mantle at  the bottom   to  the cooler  mantle  at the top While Convection currents in the core move thermal energy causing  the rising and sinking of warm and cooler molten rock inside Earth, thereby maintaining the motion of tectonic plates and  creating a balance in the earth.

Answer:

Conduction and Convection

The different forms of the beef cattle color gene are called_

Answers

The answer is right there click on it 271 the beef is colored red

The different forms of the beef cattle color gene are called "alleles"

What are alleles?

Alleles are alternative versions of a gene that arise from mutations and are located at the same position on a chromosome.

In the case of beef cattle, the color of the animal is determined by the interaction of multiple genes, including the color gene. The color gene can have different alleles that influence the color of the animal's coat. For example, one allele may result in a black coat color, while another allele may result in a red coat color.

The combination of alleles that an animal inherits from its parents determines its genotype, which in turn determines its phenotype or observed traits. Therefore, the different alleles of the beef cattle color gene can result in different coat colors, patterns, and markings in the cattle population.
