Well, lets go over each one and think of how our body uses each part.

A. If we're cold, there's no reason for it to dilate. When we dilate our vessels, we're going to have more blood flow to that area. We don't want more blood flow to that area why? Because we'll begin to lose heat that way. We will actually vasoCONSTRICT instead to shunt the blood away from the surface to preserve our internal body heat. Therefore, this is NOT an option.

C. Secretion of sebum on the skin is not used to protect against the sun. Our sebum is actually used to keep out bacteria and microorganisms. This is NOT an option.

D. Depending on the wording this one **could** be correct but because it says that it's adding their sweat, that's false. The eccrine and the apocrine glands are two sweat glands, though.

E. Blood vessels near the surface of the skin can dilate, increasing blood flow and heat loss. This is TRUE! In order for us to get rid of some of our heat, the vessels will dilate and causes the blood to enter to the surface of the skin allow the heat to rise up and out and we can get rid of the excess heat.

So, now we've broken them all down, you can see that the only response that is correct is E.

Hard water is not considered a health hazard. However, it has been stated by the National Research Council that hard drinking water usually donates a small amount towards entire magnesium and calcium in the human dietary requirements.

They further state that in some of the cases, where dissolved magnesium and calcium are very large, water could be a prime contributor of magnesium and calcium to the diet. However, very high hardness, that is, above 300 ppm that is not usual of drinking water arising from surface water, may be related to the higher threat of kidney stones and cardiovascular diseases.

In the majority of the cases of kidney stones, the blood in the body of human being, due to some kind of inherent issues, begins to absorb more calcium from water and food that is in the real sense required. As a consequence, the extra amount of calcium gets deposited on the walls of the kidneys in the process of excretion.
