White muscle fibers have earned the name âfast twitchâ because they contract in .01 seconds or less. Their contractions are fueled by oxygen, which contributes to the white color. Elite sprinters may have up to 80% more white muscle fibers than red since their performance relies on this type of tissue.hite muscle fibers have earned the name âfast twitchâ because they contract in .01 seconds or less.

wikiHow to Differentiate Between Mitosis and Meiosis. Mitosis and meiosis share some similarities, but the processes have distinct differences as well. Gametes are produced through meiosis, and are crucial to sexual reproduction; these are the egg and sperm cells, as well as spores and pollen. Mitosis is part of the reproduction of every other kind of cell in the body.
There are two major differences between mitosis and meiosis. First, meiosis involves not one, but two cell divisions. Second, meiosis leads to the production of germ cells, which are cells that give rise to gametes.Germ cells are different from somatic cells in a critical way.itosis and meiosis are similar processes in that they both result in the separation of existing cells into new ones. They differ, however, in their specific processes as well as in their products. The reason for these differences lies in the difference in the class of cells that each process creates.
