Describe the life cycle of an organism
associated with human disease.

A bite from a female Anopheles mosquito such as
this may transmit malaria.
How could we use what we know about the
transmission and infection of malaria in new and
different ways?

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

8
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.

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.

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

11
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
