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.
Answer:
Enveloping our planet and protecting us from the fury of the Sun is a giant bubble of magnetism called the magnetosphere. It deflects most of the solar material sweeping towards us from our star at 1 million miles per hour or more. Without the magnetosphere, the relentless action of these solar particles could strip the Earth of its protective layers, which shield us from the Sun’s ultraviolet radiation. It’s clear that this magnetic bubble was key to helping Earth develop into a habitable planet.
Answer:
crossing over
Explanation:
This occurs during prophase I and metaphase two of the cell cycle. Two homologous sister chromatids pair up and exchange DNA in order to increase genetic variation.
