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

Like plants, human beings have similarities and differences. God gave us talents which He wants us to use. What can you do best?
asambeis [7]
Well, humans have talents. Whether those talents are god given is up for debate. I'd argue those talents are a result of millions of years of evolution and natural selection as proven by Charles Darwin, not given by an unproven deity, but I don't know what school year you are in so you may not have escaped the years where religion is forced upon you :P

Anyway, if you're being asked this question, what do <em>you </em>like doing? I'd say my talent lies in science, as I was the top performing physicist throughout my gcse years, and I love the subject. In my opinion what you do best is what you love doing most, as if you have a passion for something it will almost always be your best talent. I can't answer that question for you.

Sharing this talent to others is basically teaching and also spreading your passion for your talent to others. They probably won't ever be as good as you because they will have their own talents and passions, but you can give them an insight into it by teaching them what you know and encouraging them to invest some time into it.
