Answer #1

8. The main advantage that process of crossing over brings to reproduction is that it act as a source of bringing genetic diversity in a population. And genetic variability is very important for the long term survival of a species.

9. The method of cytokinesis cannot work in plant cells as plant cells have walls so the cleavage furrow cannot be formed. Instead a cell plate is formed in plant cells during division. Animal cells lack cell wall so they can easily proceed through cytokinesis.

    Question 26 (1 point) How is cytokinesis in plant cells different from cytokinesis in animal cells? Cytokinesis in plant cells requires formation of a cell plate; cytokinesis in animal cells requires formation of a ring of actin. Cytokinesis in plant cells occurs during G2; cytokinesis in animal cells occurs in the M phase of the cell cycle. Cytokinesis in plant cell results in one large cell with two nuclei; cytokinesis in animal cells results in two cells, each with one...
