Which answer correctly associates a phase of mitosis with what happens to chromosomes during that phase? which answer correctly associates a phase of mitosis with what happens to chromosomes during that phase? anaphase: sister chromatids separate. telophase: chromosomes condense. prophase: chromosomes are replicated. prometaphase: chromosomes complete their migration to the middle of the cell

The answer which correctly associates a phase of mitosis with what happens to chromosomes during that phase is definitely anaphase: sister chromatids separate. During prophase, chromosomes are condensed in wide range. During the next one,  telophase, the chromosomes are far less condensed than during prophase. And during anaphase they are attached to the spindle.

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.
