ANSWER FOR QUESTION 1:
The most common type of E. coli infection that causes illness in people is called E. coli O157, which produces a toxin known as Shiga-toxin. Shiga-toxin producing E. coli is abbreviated as STEC. Symptoms of infection with this germ include watery or bloody diarrhea, fever, abdominal cramps, nausea, and vomiting.
ANSWER FOR QUESTION 2:
Some other germs don’t cause as many illnesses, but when they do, the illnesses are more likely to lead to hospitalization. Those germs include: Anyone can get sick from eating contaminated food. Follow four simple food safety steps —clean, separate, cook, and chill—to lower your chance of food poisoning and to protect yourself and your loved ones.
It depends on the type of interaction, but this typically wouldn't be an environmental scientist at all.
Explanation:
A primatologist, or a biological anthropologist, is most likely to study interactions among gorillas. Primatologists study primate behavior, ecology, intelligence, anatomy, and so forth.
A biologist or ecologist could also study gorillas and this wouldn't be unusual. They would likely study gorillas from a different perspective than a primatologist, who would be trained mainly in primates. A biologist would typically have a broader background that expands beyond primates.
Environmental scientists typically wouldn't study gorillas, although it's not impossible for someone to step outside of their field a bit.
Please note that these are all just generalizations. While most people studying gorillas come from a background in primatology, there are no steadfast rules determining who can study what.
Answer:
C
Explanation:
A is both gain b is one eats the other and d is one eats a little part of the other
They both utilize their ability of photosynthesis.
Answer:
A hypertonic environment will result in cell shrinkage due to osmosis. However, this question is unclear because it's not the lack of water that causes shrinkage, it's the loss of cell water due to there being more concentrated aqueous particles outside of the cell vs. inside of the cell. I would still go with hypertonic though.
