Answer:
The correct answer is option D.
Explanation:
The vasoconstriction or the narrowing of the blood vessels regulate the filtration rate of the glomerulus. The afferent arteriole vasoconstriction decreases the flow of blood to the glomerulus thus, decreases the filtration rate
The vasoconstriction of the efferent arteriole increases the glomerular filtration rate due to the increase in the blood level in the glomerular capillaries.
Thus, option D is the correct option.
Answer:
The correct option is : a. causing threshold to be reached more quickly
Explanation:
Norepinephrine, also known as noradrenalin, is an organic compound, which belongs to the catecholamine family. It acts as a hormone and a neurotransmitter in the brain and the body and also impacts the heart.
It is one of the hormones secreted by the adrenal medulla. Norepinephrine is a part of the fight-or-flight mechanism of the body. It acts by binding to the β-1 receptors and opens the chemical or ligand gated calcium and sodium ion channels. Therefore, <u>it causes the threshold to be reached faster </u>by increasing the rate of depolarization and thus causes heart arrhythmia.
Therefore, <u>Norepinephrine acts on the heart by </u><u>causing threshold to be reached faster.</u>
Answer:
The answer is: Testosterone
Explanation:
Testosterone is an androgen and primary male sex hormone produced by the gonads. In males, this hormone is responsible for the development of the male reproductive tissues, and promoting the secondary sexual characteristics in males such as growth of body hair, increase in the bone mass and muscle mass.
Since Lillian consumes 2100 kcal of foods and beverages and expends a total of 1800 kcal, then her body is in a state of positive energy balance.
<h3>What is a state of positive balance?</h3>
The expression 'state of positive energy balance' indicates a difference between the calories consumed and burned.
This state of positive energy balance is due to higher consumption of calories regarding calories burned each day.
In conclusion, since Lillian consumes 2100 kcal and expends a total of 1800 kcal, then her body is in a state of positive energy balance.
