What is on a transplanted organ that causes the transplant recipient's body to reject it?
Delvig [45]

Answer:

Major histocompatibility complex (MHC) antigens

Explanation:

The process in which recipient body rejects the transplanted organ is called a allograft rejection or transplantation rejection.

A transplanted organ contains Major histocompatibility complex (MHC) antigens which are required to be accepted by the recipient's body to function properly but T cells in recipient's body become alloreactive and recognize MHC antigens (donor-derived antigens) as foreign and starts making antibodies against it. Which means the recipient's body is rejecting the  transplanted organ.

Hence, the correct answer is "Major histocompatibility complex (MHC) antigens".

Genetics is the most important factor that affects your physical fitness.<br> a. True<br> b. False
faltersainse [42]
<span>This is false. Everyone is unique in this aspect and although genetics can help you, or make life harder, it also falls down to personal behavior and habits. There are no genetics that can save you from constant overeating and there are no genetics that can prevent you from working out, at least to your possible extent.</span>

A woman takes a man to court claiming that he is the father of her son and that the man should be required to pay child support.
Anastasy [175]

Answer: No

Explanation: Since when a child is born it has DNA from both. As an example, the mom has brown hair, father has blonde hair, the child would take the DNA for the type of hair they get, either blonde or brown. So since its blood, the fathers is A, and the boy's is B, therefore it didn't take any of their DNA's so nope, he isn't the father.
