Answer:
Antibodies are produced by specialized white blood cells called B lymphocytes (or B cells). When an antigen binds to the B-cell surface, it stimulates the B cell to divide and mature into a group of identical cells called a clone.
Explanation:
The IA allele encodes the A blood group antigen, IB allele encodes B, whereas, i encodes O blood group antigen.
<h3>What is antigen?</h3>
Any substance that causes the body to make an immune response against foreign substance. Antigens include toxins, chemicals, bacteria, viruses etc that come from outside the body.
So we can conclude that the IA allele encodes the A blood group antigen, IB allele encodes B, whereas, i encodes O blood group antigen.

Answer:
Found in Bacteria ( and other prokaryotes). They recognize and bind to specific sequences of DNA called restriction sites
Answer:
The answer is the first option: Since the polar cytoplasm contains information to form germ cells, germ cells would form in the anterior region.
Explanation:
If polar cytoplasm is transplanted into the anterior end of the egg just after fertilization, pole cells will develop there at the anterior end, as much as they would normally develop if they are transplanted to the posterior end of an egg. Usually, Polar cytoplasm is localized at the posterior end of eggs through maternal genes.
Answer:
They need energy to perform functions such as growth, maintaining balance, repair, reproduction, movement and defense.
