"Do algae grow more in water with a high salt content than in water without salt?"
Answer:
Anaphase
Explanation:
Before the mitosis process (where cells multiply creating two new daughter cells from a single cell) chromosomes are replicated and remain attached to their replicates, then they are condensed forming microtubules as they align on the metaphase plate. <em>Now the sister chromatids (replicates) begin to separate to the opposite poles due to the action of the spindle in </em><u><em>anaphase</em></u> (You can observe this in the image I added). Then telophase begins when the nuclear envelope forms back again and chromosomes begin to unroll.
