Which of these best describes the primary goal of meiosis? a) the nucleus is divided without mutation. b) a single cell divides into two daughter cells. eliminate c) all chromosomes are replicated and passed on to the daughter cells. d) daughter cells are produced with only half the chromosomes of the parent cell.

The primary goal of meiosis is to create four gametes, which are cells with only half the chromosomes of the parent cell.
The correct answer is D.

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.
