Is mitosis an example of asexual reproduction?

Q. What are peroxisomes?

Q. Prokaryotic organisms undergo cell division by

1. budding
2. binary fission
3. mitosis
4. meiosis

Q.

What is the difference between mitosis and Amitosis?

Q.

Bacteria and viruses are favourite experimental organisms for studying the genetical phenomenon of living organisms, which of the following is an appropriate reason for such a choice:

1. They have a very simple method of sexual recombination.

2. They are tough, they do not die easily.

3. They have a very high rate of reproduction.

4. They have a very long life-span which makes long-term studies possible.
