<span>These are:
1. <u>Number of microbes</u>: if there is a lot of microbes, then more time is needed to kill all of them.
2. <u>Characteristics of microbes</u>: some microbes have resistance genes, so they will not react to agents they are resistant to; some microbes have protective structures so treatment will be inhibited.
3. <u>Time of exposure</u>: different agents will need different time to kill microbes.
4. <u>Environment</u>: the effect of temperature, pH, organics both on microbes and agents.</span>
I think the correct answer from the choices listed above is option B. Lipid is the organic molecule which is responsible for the insulation of internal organs against shock. It can act as a shock absorber in order to protect important organs and also it insulate the body from extreme temperatures.

As photosynthesis is a process that requires sunlight, the rate of this process will be 0 in a room without any light.
However, even if the dark room has very little light, it may still not be enough for photosynthesis to occur. This process requires certain levels of sunlight.
