Answer:

The correct answer would be D. to process information and form a response.

Central nervous system (CNS) is a part of nervous system that includes brain and spinal cord.

The brain is main controlling and processing unit of the body. The brain has four lobes (temporal, occipital, Parietal, and frontal lobe) in which different stimuli are processed and responses are generated.

The spinal cord acts as a connecting link between the brain and the rest of the body with the help of peripheral nervous system.

Together, brain and spinal cord process information and control all the voluntary and involuntary movements of the body.

Your client's campaign is getting a lot of clicks, but the conversion rate is low. which approach could help improve your client

yuradex [85]

The answer would be: <span>Make sure the landing page is closely related to the ad
</span>
To have high conversion rate, the landing page should give an accurate advertising that closely related to it. Increasing the budget will increase the conversion number, but not the rate. Increasing the CPC bid or broaden the list of keyword won't increase the conversion rate either.

Neville has low blood pressure and his pituitary started producing a homorone to maintain water balance his blood pressure event

ivanzaharov [21]

Answer: The options are missing in the question,the options are;

A) Positive feedback will stop the release of this hormone.

B) Positive feedback will speed up the release of this hormone.

C) Negative feedback will speed up the release of this hormone.

D) Negative feedback will stop the release of this hormone.

The correct answer to the question is option D

NEGATIVE FEEDBACK WILL STOP THE RELEASE OF THIS HORMONE.

Explanation: The hormone the will be produced is known as Antidiuretic hormone (ADH).it is otherwise known as VASOPRESSIN.It is secreted by the posterior lobe of the pituitary gland.

The main effect of Antidiuretic hormone is to reduce urine output,(diuresis is the production of large amount of urine). Antidiuretic hormone acts in the distal convulated tubules and the collecting ducts of the nephrons of the kidneys,it increases their permeability to water and more of the glomerular filtrate is reabsorbed. Antidiuretic hormone secretion is determined by the osmotic pressure of the blood circulating to the osmoreceptors in the hypothalamus.

As osmotic pressure rises,for example as a result of dehydration, secretion of Antidiuretic hormone increases. With this,there is Increased reabsorption of water reducing the amount of urine produced.This implies that more water is retained in the body making the rise in the osmotic pressure of the blood to be low,for example,after a large fluid intake, secretion of Antidiuretic hormone is reduced,less water is reabsorbed and more urine is produced.

At high concentrations,for example after severe blood loss, antidiuretic hormone causes smooth muscle contraction, especially vasoconstriction in small arteries.this has a pressor effect,raising systemic blood pressure.
