Two successive nuclear divisions occur, Meiosis I (Reduction) and Meiosis II (Division)
there are two division in the mitosis process.
Meiosis consists of 4 divisions in the nucleus. Two new haploid cells are born by the division of 2 other haploid cells. Mitosis divides them into 2 divisions.
Two.

They replicate before meiosis begins, as it is the division phase. The chromosomes duplicate during interphase which is right before the beginning of meiosis. After going through meiosis I the chromosomes DO NOT duplicate nor do they cross over they simply continue on. Hope this helps. :)

A cell undergoing meiotic division will divide twice, yielding 4 haploid cells.
they double 30 times its wight

I think into two in mitosis and into four in meiosis. Hope this helps.

Twice. When the cell starts off there are 46 chromosomes present. This mutliplies to 92, right before it is going to divide. Then you are left with two daugter cells that have 46 chromosomes each. The second part of meiosis, each of these cells breaks into two. And this will lead to having four daughter cells with 23 chrosomes each.
twice
To be more accurate the nucleus doesn't split in mitosis because after DNA replicates in interphase and prophase starts nuclear membrane is removed and there is no longer a nucleus just free chromosomes. These separate in anaphase and then in telophase where two daughter cells are going to be produced the nuclear membrane reforms as well as the nucleolus forming two cells with identical nuclei.

1 time only which is done during the only interphase in meiosis.
twice It divides twice creating 4 daugther cells with 23 chromosomes each.
Meiosis divides twice since it is trying to duplicate the cells to create two new daughter cells for the creation process in species. It is the opposite of mitosis.
