<span>The
mass of an atom comes from the protons and neutrons that are found in the
nucleus. The number of protons is the atomic number of an element. To find the
number of neutrons, subtract the atomic number from the mass of an atom. So the number of neutrons are 20 (mass number) - 5 (atomic number) = 15 neutrons.</span>
Meiosis
Explanation:
The process in maple trees that decreases the chromosome number in the pollen cells from 52 to 26 is called meiosis.
Meiosis is an important cell division process in which diploid cells are turned into their haploid number.
- In meiosis the cells divides into half and produces four daughter cells from the diploid 2n cells.
- The cell divides twice here. It is common in all sexually reproducing cells.
- It also occurs in all single celled organisms that reproduces sexually.

I don't quite know if this helps but in the early 2000's the majority of coal was produced in the western parts of the Mississippi
