Explanation:
The phase of Prophase I of meiosis is very long and divided into 5 subphases: Leptotene, Zygote, Pachytene, Diplotene, and Diakinesis. During a phase of the Diplotene, the degree of condensation is high, which allows individualizing the sister- chromatids that remain attached by the cohesins. The synaptonemal complex disintegrates, and from the centromeres begins a repulsion between homologous chromosomes, which remain associated only with the places where they occur as permutations.
These sites are called chiasmas (Greek, crossed) because they show the crossover of homologous chromatids. Chiasmas represent the cytological finding of the occurrence of permutation. The presence of at least one bivalent chiasm is essential to ensure the correct segregation of the homologous chromosomes in anaphase I.

Answer b is the option. Because of the nature of a scientific hypothesis moves answers <span>problem.</span>
The answer is A. Removing waste.
All cells reproduce by duplicating its DNA & dividing into two (MITOSIS), Cells MUTATE resulting in incorrect changes to DNA; mutation occurring over many generationsCells are all living things are made up of cells. Cells are the basic units of structure and function in living things and Living cells come only from other living cells.
