Female mosquitoes spread diseases when they bite humans to obtain blood. it is only
the females that do the biting. research is being conducted to alter the dna of male
mosquitoes. these altered males could then mate with normal female mosquitoes. all of
the resulting female offspring would have wing defects that prevent them from flying.
-- one assumption from this research is that the
(1) altered males would begin to bite humans and spread the diseases
(2) female offspring would be unable to bite humans, since they cannot fly
(3) altered males would not be able to reproduce
(4) female offspring would become larger in size
-- the method used to alter the male mosquitoes is an example of an application of
(1) a feedback mechanism (3) biotechnology
(2) selective breeding (4) physiology

Haven't done living environment in a few years, but the assumption should be "2) female offspring would be unable to bite humans, since they can't fly" and the method would be 3) biotechnology. The answer to "assumption questions" can usually be figured out by just reading the information given. Since its talking about FEMALE mosquitoes BITING HUMANS and spreading diseases, the second answer is most relevant. The second question requires you to understand the definitions of each answer choice (or atleast the correct one). The most relevant answers would be 2 and 3, as those refer to humans changing the characteristics of a species. However, again, referring to the information given, we know that the research being conducted is with the DNA of male mosquitoes being altered. This is not an example of selective breeding, but rather of biotechnology.

The answer should be a
