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?
<span>continue to divide even when they are tightly packed together.
Hope this helps(;</span>
A population is all the organisms of the same species in a group, like humans. Population is different from a community in that a population is every organism of the species grouped as a whole, and a community is a certain number of organisms within the whole population. That may not make sense, but that’s as good as I can describe it.
Horizontal or transverse or axial cut is if you cutting the object with the horizontal plane. The cut would look like ( -- ).
Vertical or longitudinal is cutting in the vertical plane. The cut would look like ( | )
<span>There is also coronal cuts which were a cut with direction from front to back. </span>
