SSCE VCE Biology Immunity and Disease Response: Female mosquitoes require blood

Question

Female mosquitoes require blood as a source of protein for egg development. If a mosquito carries a disease-causing agent, such as a virus or a protozoan parasite, it can be transmitted to a human (or other animal) during a bite. The life cycle of mosquitoes depends on a ready source of water. Mosquito larvae hatch from eggs laid on the water and develop into pupae, which have a small air tube that attaches to the water surface to obtain oxygen.

The most commonly reported mosquito-transmitted disease in Australia is the Ross River virus (RRV) disease and occurs in all states of Australia. Health departments produce pamphlets that advise people on actions to reduce the number of mosquitoes.

The advice is likely to include directions to

A. keep swimming pools free of chlorine.

B. stock any garden pond with fish that eat mosquito larvae.

C. keep windows and doors open and uncovered to allow airflow.

D. keep well away from animals that may have been bitten by mosquitoes.
