1. How does the body adjust to a higher altitude?
Anni [7]

During acclimatization over a few days to weeks, the body produces more red blood cells to counteract the lower oxygen saturation in blood in high altitudes. Full adaptation to high altitude is achieved when the increase of red blood cells reaches a plateau and stops.Heart rate is controlled by the two branches of the autonomic (involuntary) nervous system. The sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS). ... At the beginning of exercise, your body removes the parasympathetic stimulation, which enables the heart rate to gradually increase.

D)all of them

The rate of kidney filtrate formation would normally be dependent upon all of the following factors except __________.
Anton [14]

Answer: blood calcium level

Explanation:

There are several factors affecting the rate of kidney filtrate formation including filtration membrane integrity

, systemic blood pressure, and renal artery/arteriole diameters.

Filtration membrane integrity

: It regulates the filtration of small fitrates and large filtrates. It is very important to handle the osmotic pressure of salts, if it will get damage the filtration will not take place properly.

Systemic blood pressure: systemic blood pressure is very important factor as it affects the Glomerular Filtration Rate (GFR). Low blood pressure or volume due to dehydration can result in decreased GFR.

Renal artery/arteriole diameters: The filtrate move through the renal artery and if it's diameter will increase or decrease it will affect the movement of filtrate. if diameter will decrease it can block the renal artery and can cause a huge damage.

Blood calcium level do not have any role in the kidney filterate formation or renal regulation.

Hence, the correct option is blood calcium level.
