The right answer is A patient who is Rh– can receive only Rh– blood.

The blood group is not the only thing that matters, it adds a category: rhesus. Rhesus refers to a red blood cell antigen that is on their wall. There are two blood group systems: Rh positive (Rh +) and Rh negative (Rh-).

Rhesus is positive in people who have this antigen. It concerns the majority of the population. Negative rhesus refers to people without the antigen. This rhesus factor is especially useful to know if a blood transfusion is feasible between two people.

The blood transfusions can be "iso-rhesus", that is to say between Rh + and Rh- but only in one sense: Rh- can give to Rh + but Rh + can not give to Rh-. Again because of the presence of antibodies directed against the antigen in Rh- people.

Yes it is important to know a person's Rh factor, but you can give an Rh+ patient Rh- blood only once because after that their body will build a defense mechanism against it and the blood will be rejected the second time.

Why don't people's cells starve from lack of glucose while they are fasting​
GenaCL600 [577]
Answer:


Fasting can definitely raise blood glucose. This is due to the effect of insulin falling and the rising counter-regulatory hormones including increased sympathetic tone, noradrenaline, cortisol and growth hormone, in addition to glucagon. These all have the effect of pushing glucose from liver storage into the blood. This is normal. If you are not eating, you want to use some stored glucose. The question is this – if you are not eating, and your blood glucose went up, where did that glucose come from? It can only have come from your own body (liver). So, it’s a natural phenomenon, and the fasting now allows your body to use some of the glucose for energy.

Answer:

I'm a bit confused with the question... it is worded weird.

Explanation:

By the looks of it the controlled variable is how far you dip the paper towel in the water, the independent variable is the bowl filled with water, and the dependent variable is the water climbing up the towel.

FYI: I'm not 100% positive, but I'm pretty sure these are correct for the most part. Sorry I couldn't be more help!
