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
Answer:
Earth is the third planet from the Sun at a distance of about 93 million miles (150 million km).
Answer:
when the pores are completely filled in the rocks and soil
Explanation:
The zone of saturation is part of the divisions of ground water systems. It is the zone in which the pore spaces within the rock are completely filled with water.
The zone of saturation is where the aquifer lies in a body of water and it is the ground water prospect. Pore spaces can also be filled with hydrocarbons.
Above the zone of saturation is the water table. The water table defines the upper layer of the zone of saturation above which the pore spaces are filled with gas or no water can be found.
Assuming this is supposed to be a multiple choice question- I think the correct answer would be “early onset of spring change in marine ecosystems” because it looks like the question is asking what it wouldn’t affect, and I’m sure if the people had to leave, that animals would’ve all had to leave as well!
