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?
First,get something where you can get the fish and where you can fill it up with water then just start taking out the mixture with a small net
Answer:
The periodic table of elements arranges all of the known chemical elements using this method. Elements are arranged from left to right and top to bottom in order of increasing atomic number. Order is usually according with the increasment (Is this a word?) of the atomic mass.
Explanation:
Have a good day :)
The weakest died out and only the intelligent and strong survived to pass on the most useful traits, determining the way a species evolved - growing more intelligent or athletic as a result of these patterns.
