Answer
D. tend-and-befriend; women
Explanation
It refers to protection from offspring (tending) and seeking out the mutual defense obtained from a social group (befriending). Typically, psychology suggests that this has evolved from female responses to stress. In this case, initiating small talks in a waiting room is a way of calming nerves and gaining reassurance by utilizing the social interaction.
Meiosis occurs in the sex cell of human body. They are present in the form of sperms cell in males and in female they are present in the form of eggs. Meiosis is the procedure of cells part into four haploid cells, along these lines decreasing the chromosome number considerably in every cell. They likewise offer ascent to gametes in the human body, and plant spores in plants.
Meiosis happens in the sex cells, so the sperm and egg cells in the human body, to make significantly a greater amount of themselves.
Meiosis is an uncommon sort of cell division. In contrast to mitosis, the manner in which ordinary body cells separate, meiosis results in cells that just have a large portion of the typical number of chromosomes, one from each pair. Consequently, meiosis is regularly called decrease division.
The essential capacity of meiosis is the decrease of the ploidy (number of chromosomes) of the gametes from diploid (2n, or two arrangements of 23 chromosomes) to haploid (1n or one lot of 23 chromosomes).
Meiosis is significant in light of the fact that it guarantees that all life forms delivered by means of sexual proliferation contain the right number of chromosomes. Meiosis additionally creates hereditary variety by method for the procedure of recombination.
On the off chance that meiosis does not happen appropriately, an egg or sperm could finish up with an excessive number of chromosomes, or insufficient chromosomes. Upon treatment, the infant could then get an additional chromosome (called a trisomy), or have a missing chromosome (called a monosomy).
Some single cell creatures and a few plants don't recreate explicitly through meiosis. Or maybe, they use mitosis just to make precise copy of their cells. The real inconveniency of this methodology is that the majority of the living beings in a populace or the majority of the plants in a region will have precisely the same DNA. Mitosis takes into consideration cells to deliver indistinguishable duplicates of themselves, which implies the hereditary material is copied from parent to little girl cells. Mitosis produces two girl cells from one parent cell. The general procedure of meiosis produces four little girl cells from one single parent cell.
Rather than meiosis I, meiosis II takes after a typical mitosis. Amid meiosis II, the sister chromatids inside the two little girl cells separate, framing four new haploid gametes. The mechanics of meiosis II is like mitosis, then again, actually each dividing cell has just a single lot of homologous chromosomes.
Answer: Periods - 3
Quarters - 4
Games - 3
Matches - 4
