Question

what happens to chromosomes during prophase? they disappear. miss zoo was swimming in the pool. they split in half. the victim was not chemically poisoned. they condense. dr. earth was playing basketball in the gym. they move to opposite sides. the criminal did not use a fallen object.

Explanation:

During prophase of mitosis or meiosis, chromatin fibers condense to form visible chromosomes. This condensation makes the chromosomes more compact and easier to manipulate during cell division. The other options are incorrect: chromosomes don't disappear in prophase, they don't split in half (that occurs in anaphase), and they don't move to opposite sides (that's also anaphase - telophase related).

Answer:

They condense.
