how factors such as blood pressure blood volume blood viscosity resistance disease and exercice affect blood flow
schepotkina [342]

Blood is essential for many organisms, such as humans and animals, for its important function of transporting substances (food, oxygen), vitamins, waste (carbon dioxide), hormones, etc. to all tissues and cells of the body.

1) Blood volume

If the blood volume increases ==> the blood flow increases.

2) Viscosity of blood

If we have an increase in blood viscosity ==> we have a decrease in blood flow

3) Peripheral Resistance

If there is an increase in peripheral resistance ==> the blood flow decreases

4) Diameter of blood vessels

If we have an increase in diameter of

blood vessels ==> decreased peripheral resistance ==> increased blood flow

5) Blood pressure

If the blood pressure increases ==> the blood flow increases.

6) In case of diseases

In the case of atherosclerosis or acute coronary syndrome ==> blood flow decreases.

7) Physical excercises:

During physical exercises ==> the heart rate increases ==> the blood flow increases.

Do you think Peacocks would be in Hardy-Weinberg Equilibrium? Why or why not?
Slav-nsk [51]

Peacocks would not be in Hardy-Weinberg Equilibrium

Explanation:

This can be justified by the mating patterns of the female peacocks. They do not choose their mates randomly but look out specifically for bright attractive plumage in their male partners and then select them.

Hardy-Weinberg's Equilibrium of evolution mechanism was based on facts like random mating, no natural selection,  mutation, absence of gene flow, and infinite population size.

They stated that organisms mate randomly with each other without any specific or a particular preference in the phenotypes of their opposite mates
