When and how is the spindle formed?

It is formed in prophase of meiosis

Explanation:

The spindle is formed under the direction of the microtubule organizing center (MTOC).

The spindle develops in the cytoplasm of a cell in prophase of either mitosis or meiosis. It is a barrel-shaped structure, made up of many spindle fibers, which are microtubules of the cytoskeleton. The two ends of the spindle taper towards points that are called the poles of the spindle, and these two points in the cytoplasm of the mother-cell will be the sites of formation of the daughter-nuclei in telophase.

the darker peppered moth species were favored due to the fact that the industrial revolution had made all the nearby trees a darker color instead of white.

a. seed plant structure. 1. the three main plant organs are roots, stems, and leaves. a fourth kind of tissue, meristematic tissue, is responsible for plant growth. meristematic tissue is the only plant tissue that produces new cells by mitosis. plants can lose water out of their leaves as they exchange gases with the air
