1. A human body cell has 46 chromosomes. If your big toe is made of 1million cells, how many chromosomes are in your big toe?

3. If a young plant gone began as one cell and has gone through mitosis 10 different times, how many cells does it have?

2. A red blood cell has a cell cycle that lasts for 120 days. How many hours does it live? Most of its life is spent in which phase? (interphase, mitosis, or cytokinesis)
