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.
Meiosis produces 4 haploid cells. Mitosis produces 2 diploid cells. The old name for meiosis was reduction/ division. Meiosis I reduces the ploidy level from 2n to n (reduction) while Meiosis II divides the remaining set of chromosomes in a mitosis-like process (division).Most of the differences between the processes occur during Meiosis I.eiosis is a special type of nuclear division which segregates one copy of each homologous chromosome into each new gamete. Mitosis maintains the cell's original ploidy level (for example, one diploid 2n cell producing two diploid 2n cells; one haploid n cell producing two haploid n cells; etc.).
