LO. Biology Organization of Living Things Benchmark 2 Describe the life cycle of an organism associated with human disease.

A bite from a female Anopheles mosquito such as this may transmit malaria. The yellow malaria parasites burst out of infected red blood cells. How could we use what we know about the transmission and infection of malaria in new and different ways? Click here for Life Cycle of Malaria

Life cycle of organisms associated with human diseases, such as Lyme disease—tick Malaria—mosquito Parasites. Real-world Contexts

Which of the following is an example of a disease-carrying organism and the disease it spreads? A. tall grass and Lyme diseasetall grass and Lyme disease B. the deer tick and Lyme diseasethe deer tick and Lyme disease C. the Nile River and West Nile diseasethe Nile River and West Nile disease D. Insecticides and malariaInsecticides and malaria

A. tall grass and Lyme disease Incorrect: Lyme disease is bacterial disease transmitted to a person by a bite of a deer tick. Although the tick may be present in tall grass, it is not carried by the grass itself. Return to the question

B. the deer tick and Lyme disease Correct: Lyme disease is bacterial disease transmitted to a person by a bite of a deer tick. Although the tick may be present in tall grass, it is not carried by the grass itself. Return to the question

C. the Nile River and West Nile disease Incorrect: the West Nile virus that causes West Nile disease is carried by mosquitoes. A river is not an organism Return to the question

D. Insecticides and malaria Incorrect: Malaria is transmitted by a mosquito (like West Nile) Insecticides may be used to stop the spread of the disease by killing off the mosquitoes Return to the question
