Answer:
The correct answer is D. proliferation and differentiation.
Explanation:
Primary immune response occurs due to the first exposure of an antigen to the immune system. The primary immune response is generally delayed by many days because it takes time for B and T cells to become cloned and to proliferate and differentiate.
Then after several days of proliferation and differentiation of activated T and B cells, T cells become effector T cells and B cell becomes plasma cells which then eliminates the antigen. Memory B and T cells are also produced during this process which helps in generating a quick immune response during the second and subsequent exposure of that antigen.
So the correct answer is D. proliferation and differentiation.
Answer:
the answer is C
Explanation: The deep ocean circulation of water is caused by convection currents in water that allow cold water to rise and warm water to sink.
Proteins have all of the properties except genetic material.
<h3>What do you mean by Proteins?</h3>
Proteins may be defined as naturally emerging, extremely complicated substances that consist of amino acid residues joined by peptide bonds.
Proteins have the following properties:
- They are enzymes.
- Work as signaling molecules in numerous signaling.
- They are involved in the transport of materials.
- They provide a structural arrangement to the cells.
Therefore, proteins have all of the properties except genetic material.
