1 answer:

7 0

They only have 23 chromosomes because they go through meiosis instead of mitosis, in mitosis the chromosomes are duplicated so then you have cells with the full 46 chromosomes, however eggs and sperm go through meiosis which doesn’t duplicate the cells because when a sperm (23 chromosomes) and a egg (23 chromosomes) combine then there’s the full 46 chromosomes for the cell.

vampirchik [111]

When a body is partly or completely immersed in water (or any other liquid), then:Loss in weight of body = Weight of water (liquid) displaced by the body = Buoyant force or upthrust exerted by water (any liquid) on the body. It was Archimedes who first observed that bodies lose their weight when immersed in water.
