How wide is a water molecule
WebHow can an X chromosome be nearly as big as the head of the sperm cell? No, this isn't a mistake. First, there's less DNA in a sperm cell than there is in a non-reproductive cell such as a skin cell. Second, the DNA in a sperm cell is super-condensed and compacted into a highly dense form. Third, the head of a sperm cell is almost all nucleus. Web4 sep. 2024 · A molecule is a piece of matter that contains two or more atoms. Atoms are the tiniest pieces of matter.
