Answer:
b. They are produced by memory B cells
Explanation:
The rapid cell division in activated B cells is followed by the differentiation of daughter cells into the plasma cells. The plasma cells are the precursor for antibodies and memory B cells. The antibodies kill the antigens while memory B cells are long-lived cells.
Hence, antibodies are not produced by memory B cells but by plasma cells.
I would say this is an expository text.

Answer:
A - Cell 1 - Eukaryotic, Cell 2- Prokaryotic
Explanation:
The important<span> point is that the </span>surface area<span> to the volume ratio gets smaller as the </span>cell<span> gets larger. Thus, if the </span>cell<span> grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased </span>cellular<span> volume.</span>
