Step 1
Which of the following is an advantage for animals using internal fertilisation rather than external fertilisation?
Answer
The correct answer is A. Internal fertilisation offers significant advantages, including the prevention of dehydration of gametes. Since internal fertilisation occurs within the body, the gametes are protected from environmental conditions that could lead to their desiccation. This contrast with external fertilisation, where gametes are exposed to the environment, increases the chances of successful fertilisation and subsequent development of embryos.
