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.
Mitosis makes two identical cells. Meiosis makes four different cells. Mitosis makes two cells with exactly the same number of chromosomes(diploid cells) Meiosis makes four cells with half the number of chromosomes (haploid cells) Mitosis only takes one step. Meiosis takes two steps. In addition to that meiosis is only used for gamete production (like eggs, or sperm).
