Biology

Roman55 [17]3 years ago
4 0

Answer:

Convection currents are defined as the transfer of heat due to the bulk movement of molecules within fluids.

From past experiences, we know that heat rises. When a liquid is heated from the bottom, it will rise to the top. To take the place of the previously heated liquid, the colder liquid that was at the top before will move to the bottom and will be heated. Then that will rise to the top and the cooler liquid that was being heated first will move beck to the bottom to be heated again. The earth's heat source is from the core, which is towards the bottom if youre looking at the mantle. So the same principle applies there as well.

If a cell at metaphase of mitosis contains 20 sister chromatids, how many chromosomes will be present in a g1 cell
Alika [10]
<span>The correct answer is 10 chromosome. Mitosis is the type of cell division that takes place in the somatic cells or the body cells where the parent cells divides into two daughter cells with the same genetic composition as the parent. Therefore, the number of chromosomes in the daughter cells remains the same as that of the mother cells. The opposite is the meiosis, which involves division of a germ line cells into four daughter cells which contains half the number of chromosomes as the parent. </span>
