Answer:
III. Equal number of chromosomes.
Explanation:
Comparison between two cells, one cell just before first meiotic division and other cell ready to start mitosis is that both the cells have equal number of chromosomes.
Both the cells have an equal number of chromosomes that is 2n (diploid), where n is 23 and total chromosomes are 46 in each cell but at the meiosis at the end meiosis produces four haploid (n) daughter cells and mitosis produces two diploid (2n) cells.
Hence, the correct answer is "III. Equal number of chromosomes.".
Answer:B cell sub-type that are formed within germinal centers following primary infection. Memory B cells can survive for decades and repeatedly generate an accelerated and robust antibody-mediated immune response in the case of re-infection (also known as a secondary immune response).
