Answer:
Point A - Intrusive igneous rock
Point B - Extrusive igneous rock
Explanation:
Intrusive igneous rocks are rocks which is formed by molten magma that cools and solidifies below and within the surface of the earth, thereby forming large crystals beneath the earth surface. Examples of Instrusive igneous rocks gabbro, granite, peridotite etc.
Intrusive Ignoeus rock is formed at point A in the diagram given above.
Extrusive Ignoeus rock, on the other hand, is the opposite of Intrusive igneous rock. Extrusive igneous rock is formed when molten rocks, called magma, erupts from beneath the earth and cools and solidifies on the surface of the earth, thereby forming small crystallized rocks. Examples of extrusive igneous rocks are basalt, pumice, etc.
Extrusive Ignoeus rocks would formed at point B in the diagram above.
Answer:
Something that an antibody or T-lymphocyte binds to
Explanation:
As per the definition, antigens are the substances or molecules that are capable of inducing an immune response. When our immune system detects any unwanted substance or molecule in our body, the specific type of antibody is made against that antigenic substance and the antibody made against it binds to the antigen so that the other immune cells can recognize it and destroy it and protect us form its harmful effect. T-cell are also involved in recognizing antibodies and specific T-cell can bind to the antigen.
