How are trypanosome diseases similar to malaria? How are they different than malaria?
What will be an ideal response?
Answer: Both trypanosome diseases and malaria are caused by protozoa and are spread by insect vectors. Both parasites multiply in the blood and in some cases affect the nervous system and other organs. There are no effective vaccines for trypanosome diseases or malaria. Chronic illness in either type of disease can be debilitating or deadly. They are different in that malaria has a complex life cycle and acute forms of malaria can be deadly. Trypanosome diseases are spread by tsetse flies and "kissing bugs," while malaria is spread only by the Anopheles mosquito.

As part of the previous experiment, you monitor the growth of tree A (ants blocked from the canopy) and tree B (ants are not blocked from the canopy) over the three-year period. You expect __________ because _________
A. higher growth in tree A; the number of aphids will fall because ants are absent, and aphids are parasites of the tree B. higher growth in tree B; the natural environment is always optimized so any change (e.g., blocking the ants from tree A) will reduce the performance of all members of the network C. no change in growth; due to the size difference between the trees and the insects, the presence or absence of insects will not have an effect on tree growth
