Explanation:
The reason is because there is a thing called a 'Water Cycle'. It is basically the continuous movement of water on the surface of the Earth.
P.S. if I get it wrong, forgive me
NaCl: natriumchloride. 1 atom of each, so the 2 is too much and I (capital i here) is another element
So for the second excercise the number behind the symbol is the amount of atoms in the compound. So easily 2 atoms of Li, 1 atom of S and 4 of O
Answer:
Doubles the amount of DNA and reduces the chromosome number from 2N to N.
Explanation:
Meiosis is a cell division in which one cell divides into 2 cells in the first meiotic division and then these two cells divide into two more cells so overall 4 cells are produced from one cell. This division occurs in gamete cells.
First, the amount of DNA gets double by converting the single-stranded DNA into double-stranded DNA. Then the homologous chromosomes get separated into two different cells in the first meiotic division and till now the chromosome number is 2N.
After the second meiotic division, each sister chromatids of a chromosome gets separated into separate cells and the chromosome number in daughter cells becomes 1 N. So the major role of meiosis is to double the DNA mount and reduce the chromosome number by half in all daughter cells.
