Answer: (A) when edges become denser and gravity pulls them downward and away from one another.
During continental and oceanic plate tectonics. The plates collides with one another as a result of divergent tectonics. The edges at the point of contact gets displaced off from lighter plate and sinks at the bottom due to the effect of graviational pull. This is known as subduction. Due to force of collision these plates do not sunduct to the same location but are thrown to distinct places away from each other.
Forming H20 and a new covalent bond between the two smaller components ( The term dehydration means that water is lost). By repeating this reaction many times.
Answer:
B. All antigen receptors produced by a single B or T cell are identical and bind to the same epitope.
Explanation:
Antigen receptors are antibody protein anchored to the B-cell membrane.
They are all identical when the antigen receptors is located on one type of B cell making Binding between the receptor and epitope to occur since its structures are complementary. It's not identical when the antigen receptors is located on different types of B cell
