Answer:decompose
Explanation:
My thought process for this problem; bacteria cannot fertilize egg cells. Sperm does that through reproductive processes. Bacteria does not help organisms grow.

In cancerous cell, telomerase expresses and enhances the cell cycle division
Explanation:
In Cancer, cells divides uncontrollably as once the cell cycle is complete, the inhibitors do not restrict the cells from dividing further. These positive regulators of cell cycle if not controlled leads to continuous break down of cell and hence the cancer.
In a cancerous cell, enzyme reversing the wearing down of chromosome at the end of all cell cycle i.e telomerase expresses which in normal cases stops the cell division.
