The seven-spotted cockroach is a nocturnal species that burrows under leaf litter during the day.
djyliett [7]

Answer: C. is less likely to be eaten by a predator.

Explanation:

The adult seven-spotted cockroach is the prey of various other insects including beetles so mimicking the pattern of a beetle would send a message that it is a beetle and because the chemical irritant that the beetle has makes it get avoided by others, the cockroach gets avoided by other insects too who don't want to be sprayed.

Of course this does not always work but it works for the most part and ensures the cockroach's survival.

Kenny has a sore throat and visits the doctor. The nurse collects a throat swab, places the swab on a petri dish, and then place
Doss [256]
The answer is C: because growth at 37°C would be ideal for revealing bacteria that are human pathogens. 37°C is equivalent to 98.6°F, the normal body temperature for humans. If bacteria are reproducing at this temperature in a petri dish, they are also most likely reproducing in the body. 

Cultures are made so doctors can be sure a person is sick with a specific bacteria often in order to make sure they are taking the right medication to get better. Choice A doesn't make sense, because we wouldn't want to kill the bacteria we are trying to study. Bacteria that makes us sick is harmful bacteria and is what we are trying to isolate. Choice B doesn't make sense, because they are only being incubated at one temperature, not a range or variety. Choice D is harder to rule out, but again the doctor wants the bacteria to reproduce so they can be sure that's what is causing the infection, so it wouldn't make sense that we would put the bacteria in a temperature they would not reproduce.
