Answer:
not significant to the overall mass of the atom
Explanation:
The mass number of an atom is the combination of the mass of the protons and neutrons. Electrons are not included because their mass are so insignificant that is doesn't change the total mass much, therefore they are left out. The mass of an electron is about 1,830 times smaller than protons and neutrons.

Answer:
D. four haploid cells
Explanation:
When meiosis is complete,four haploid cells are formed from a single diploid cell. The four daughter cells produced that contains half the number of chromosome than that of their parent cell. Due to meiosis the number of chromosomes remain fixed in a species from generation to generation.
The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell. Meiosis has both similarities to and differences from mitosis, which is a cell division process in which a parent cell produces two identical daughter cells.
