During a cell division cycle, chromosome segments from two homologous chromosomes exchange places. Which result is most likely to occur following this
cycle?
A. Genetic material will be lost
B. The number of chromosomes will increase
C. The total number of genes in the cell will decrease
D. A change in gene location will occur on both chromosomes

answer: - b cells

explanation: -

there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.

That would be a working theory.
