1. Prophase
Answer: Chromosomes become visible, nuclear envelope dissolves, spindleforms
2. Metaphase
Answer: Chromosomes line up in the middle of the cell
3. Anaphase
Answer: Chromosomes separate and move to opposite ends of the cell
4. Telophase
Answer: Chromosomes move to opposite ends of the cell and two nuclei areformed.
5. What are the 4 types of tissues?
Answer: epithelial, connective, muscle, nervous
6. What are the properties of epithelial tissue?
Answer:
-Cells sit on basement mem-brane
-Has apical surface and basal surface
-Avascular
-Polarity
-Innervated
7. What occurs when the apical surface of epithelial cells separate from thebasement layer?
