I/GCSE Biology Question Analysis Topic: Biology - Short Questions

Exam Questions:

1) Why are the human testes located outside the abdominal cavity? Name the pouch in which they are present.

2) Why are analogous structures a result of convergent evolution?

Answers:

For I/GCSE Biology, you should know:

1) Testes (the site of spermatogenesis) are located outside the abdominal cavity because the process of spermatogenesis requires a lower temperature (2 to 2.5oC) than the body. The scrotum or scrotal sac is the name of the pouch.

2) Similar-functioning structures with differing anatomical characteristics i.e., analogous structures are the product of convergent evolution. It happens when two substantially unrelated groups of organisms are exposed to highly similar environments and evolve similar adaptations for survival. For instance, both insects and bats have developed the ability to fly, and both have wings as flight-related adaptations (but bats and insects have vastly different wings today than they did originally).

Work hard for your I/GCSE Biology examination!

End of analysis. Great!
