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.
Depends on the magnification you are looking for... usually, a light microscope is enough (1000x max magnification)...
An electron microscope is powered by high energy beams and can magnify many times higher than the light microscope (where magnification is limited by the wavelength of light). The magnification of an EM is on the nano scale.
(P.S.: as a chemist, I'd always choose an EM over an optical microscope as I can always zoom in or out depending on my needs) ;)
Sarin is a nerve gas that causes severe disruption to the nerve system. Decontamination is critically important. Nurse should wear protective clothing, including a respirator and rubber gloves. Immediately administer an auto-injector antidote of Atropine at 2 mg IM and 600 mg of Pralidoxine chloride. Use Atropine injections up to 3 times every 30 minutes. Use a mixture of with 10 cc bleach per liter of water for decontamination. Administer a Diazepam to control convulsions.
To what body system does this belong to? Circulatory System.
How might what is happening in this image affect the nervous system? The fatty deposit might clog your blood circulation, so you might not breath if it is clogged.
