 6. What is the significance of meiosis in sexual reproduction?

Answer: Meiosis reduces the chromosome number by half and increases genetic variation.

7. What is the role of the placenta in human reproduction?

Answer: The placenta provides nutrients and oxygen to the developing foetus.

Answer: Binary fission involves a single division, while multiple fission involves multiple divisions.

 9. How does the process of budding differ from regeneration?

Answer: Budding involves the growth of a new individual from a bud, while regeneration involves regrowing lost body parts.

 10. What is the importance of reproduction in living organisms?

Answer: Reproduction ensures the survival of a species and maintains population size.
