_________ is the division of the nucleus.
__________ results in two daughter cells.
In ______, the nuclear envelope is re-formed.
In ____, the nuclear envelope disappears.
In __________, the sister chromatids separate.
In _________, the chromosome attach to spindle fibers and line up in the middle of the cell.
Question 6
Which of the following are ways that mitosis and meiosis are different? Select all that apply.
- Mitosis results in genetically identical cells, meiosis results in genetically different cells.
- Mitosis is two divisions; meiosis is four divisions.
- Mitosis results in haploid cells, meiosis results in diploid cells.
- Mitosis results in four cells, meiosis results in two cells.
- Mitosis is for somatic cells, meiosis is for sex cells.
