IBDP Biology Question Analysis Topic: Biology - Short Questions
Exam Questions:
1) Why is Gambusia introduced into drains and ponds?
2) Construct an age pyramid which reflects an expanding growth status of human population.
3) State the role of C peptide in human insulin.
Answers:
For IBDP Biology, you should know:
1) The nickname "mosquito fish" is another name for the gambusia. A variety of planktons and mosquito larvae are consumed by the fish. The consumption of larvae helps to limit mosquito breeding, which in turn reduces the risk of mosquito-borne diseases.
2) Refer to the following diagram.
3) The proinsulin molecule's C-peptide, a 31-amino-acid polypeptide, joins the A- and B-chains of insulin. Additionally, it is known as a connecting peptide. It is crucial for the synthesis of insulin, which is necessary for regulating blood sugar.
