Explanation:
Answer: Option B) Antigens
Blood typing is based on the presence of proteins known as antigens on the outer surface of the red blood cell plasma membrane.
Explanation:
Blood groups A, B, AB, and O are determined based on the antigen-antibody reactions between donor and recipient bloods.
For instance,
- Blood type A has antigen A on its plasma membrane
- Blood type B has antigen B on its plasma membrane
- Blood type AB has both antigen A and antigen B on its plasma membrane
- while blood type O has neither antigen A nor B on its plasma membrane
So, antigens is the answer
<span>The answer would be:
reduces water loss compared to other nitrogenous wastes, but requires more metabolic energy to produce
Nitrogen waste needs to be removed out of the body. There are a few ways to remove the nitrogen waste but it will vary in the amount of energy used.
Uric acid is less soluble which makes it won't be secreted in urine, thus reducing the need to urinate and reduce water loss. But the production of uric acid need hydrolysis of ATP, so it needs more energy.
Fish will secrete the waste as ammonia which soluble in water but doesn't need ATP to synthesize.</span>
