  2. Mitosis - Wikipedia

    en.wikipedia.org/wiki/Mitosis

    The function or significance of mitosis, is the maintenance of the chromosomal set; each formed cell receives chromosomes that are alike in composition and equal in number to the chromosomes of the parent cell. Mitosis occurs in the following circumstances: Development and growth: The number of cells within an organism increases by mitosis.

  3. Cell division - Wikipedia

    en.wikipedia.org/wiki/Cell_division

    Cell division in prokaryotes (binary fission) and eukaryotes (mitosis and meiosis). The thick lines are chromosomes, and the thin blue lines are fibers pulling on the chromosomes and pushing the ends of the cell apart. The cell cycle in eukaryotes: I = Interphase, M = Mitosis, G 0 = Gap 0, G 1 = Gap 1, G 2 = Gap 2, S = Synthesis, G 3 = Gap 3.

    Again, however, this is not applicable to all sexual organisms. There are numerous species which are sexual but do not have a genetic-loss problem because they do not produce males or females. Yeast, for example, are isogamous sexual organisms which have two mating types which fuse and recombine their haploid genomes. Both sexes reproduce ...

    The studies often show different results about the body strength difference between the both sexes. Two studies, conducted in the four European Union countries, involving 2,000 participants (1,000 men and 1 000 women) concluded that females are 74 - 92% as strong as males, as many women (211 of 1,000) are still physically stronger than average men.

  6. Cell cycle - Wikipedia

    en.wikipedia.org/wiki/Cell_cycle

    The eukaryotic cell cycle consists of four distinct phases: G 1 phase, S phase (synthesis), G 2 phase (collectively known as interphase) and M phase (mitosis and cytokinesis). M phase is itself composed of two tightly coupled processes: mitosis, in which the cell's nucleus divides, and cytokinesis, in which the cell's cytoplasm and cell membrane divides forming two daughter cells.

    en.wikipedia.org/wiki/Sexual_reproduction

    Larger populations appear to respond more quickly to some of the benefits obtained through sexual reproduction than do smaller population sizes. [26] However, newer models presented in recent years suggest a basic advantage for sexual reproduction in slowly reproducing complex organisms.

    One reason why some women might not reach orgasm with a partner is also the misguided notion that penetrative sex should lead to an orgasm — which, for most women, it doesn’t on its own.
