why does the meiosis produce cells with only half the amount of DNA? How does this aid in the formation of a healthy zygote?
Andreyy89
Meiosis produces cells (germ cells or gametes) with only half the DNA, or chromosomes, as normal cells (somatic cells). This is called haploid or referred to as "n" number of chromosomes. Normal body cells have doubke that, called "2n," or diploid. For humans our n = 23, so germ cells (haploid) have only 23 chromosomes, while somatic (normal body) cells have "2n" or 46 chromosomes. It is important to only carry half the number of chromosomes or DNA (n), because it is going to combine with another half (n) when sperm meets egg during fertilization. This n + n = 2n restores the diploid number of chromosomes (DNA) in a zygote, the first cell of a future embryo, fetus, and new human being.

If a scientist is studying the attraction of water molecules to each other, what property is he or she studying?
gtnhenbr [62]

It can be intrinsic forces that can be caused by the structure and shape of water. This allows the water molecules to stick to each other.

Due to this phenomenon of water it has a spherical shape and it flows in a liner motion.

Hence, the force that is present between two water molecules is cohesion.

In general though for mammals the broad classifications would include epithelial, endothelial, connective, smooth muscle, striated muscle, cardiac muscle, neuronal, glial, and many others.
