Answer:
The correct answer is - the dependent variable.
Explanation:
In any study or research, the variable is that measured or affected by the change occurs lace in an experiment is called the dependent variable. The dependent variable depends on the factors or the variables that are changed in the experiment.
In this particular study, the variable which is measure is the height or growth of the plant which depends on the change in the hydrating supply so the dependent variable will be - the growth of the plant.
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:
The Role of Enzymes in the Digestive System. Chemical digestion could not take place without the help of digestive enzymes. An enzyme is a protein that speeds up chemical reactions in the body. Digestive enzymes speed up chemical reactions that break down large food molecules into small molecules.
