it has to do with one be more effective than the other.
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?

peripheral nervous system (PNS) are all neurons located outside the brain and
spinal cord (which is the central nervous system [CNS]). There are two types of
peripheral nervous system: sensory (afferent) neurons and motor (efferent)
neurons. The former carries bits of information from the sense organs (touch,
smell, taste, hearing, and sight) around the body to the brain and spinal cord,
while the latter transports messages from the central nervous system (brain and
spinal cord to the muscles and glands.</span>
