Practice questions testing deep understanding of sexual and asexual reproduction mechanisms.
Q1. In an orchard, a farmer grows apples using grafting, while a nearby wild forest grows apples naturally from fallen seeds. A new disease strikes both areas. The wild forest survives with some damage, but the farmer's entire orchard is wiped out. Explain biologically why the orchard was totally destroyed.
Q2. External fertilization (where eggs are fertilized outside the body) is common in frogs and fish, but rare in terrestrial animals. Why do terrestrial animals primarily rely on internal fertilization?
Q3. Assertion (A): The testes in human males are located outside the abdominal cavity in the scrotum. Reason (R): The scrotum maintains a temperature 2-3°C lower than the normal body temperature, which is essential for the production and survival of healthy sperm.
