Answer:
Exercise is important for the body to function properly.
Explanation:
Exercise helps a person to maintain the oxygen amounts in the body. Exercise, as such, enhances and regulates almost every system of the body including the nervous, respiratory, circulatory and hormonal systems.
The sympathetic division of the autonomic nervous system controls the physical activities in a person's body by detecting the low levels of oxygen and increasing amounts of carbon dioxide in the body.

Answer:
The toxic sludge covers the animals completely, and then they suffercate and dye, I don't know how else to say that
1. Suzie's hypothesis (i.e. prediction of results) is that ferns which are placed in white light will grow to a taller height after two weeks than ferns which are placed in other coloured light or in a closet.
2. Her independent variable (the thing she changes to produce a result) is the kind of light that she places each plant in.
3. The dependent variable (the thing she measures) is the height of the plants after two weeks.
4. I would say her control group would be the plant placed in the closet, because every other group is exposed to some form of light.
5. I would say that Suzie has 4 experimental groups: white, red, blue, and green light.
6. The constant variables were the amount of water each plant was given, the initial height of the plants, the age of the plants, the species of fern, and what she planted the ferns in.
7. To determine how each fern did, Suzie could measure the height in addition to noting the appearance of all the plants. E.g. did any look paler than the others?
