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.
cell. This is not the case for meiosis, which reduces the chromosome number by half. Mitosis results in the production of two genetically identical diploid cells, whereas meiosis produces four genetically different haploid cells. Mitosis is a form of asexual reproduction, whereas meiosis is an early step in sexual reproduction.
