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?
Answer:
The answer is FALSE.
Explanation:
Schizophrenia is a personality disorder that affects a person's ability to think, feel and behave clearly.
Although there is a very strong genetic component to schizophrenia, genes alone do not completely explain the illness. Rather it is believed that genes do not directly cause schizophrenia, but do make a person vulnerable to developing the disease alongside other factors such as the environment and altered brain chemistry and structure.
<span>Terrestrial radiation is energry that is emmited from the earth from the parts of solar radiation. Solar radiation is radiation and energy off the sun, however, only some of the radiation reches the eath's surface. I beleive the similarity is that both of the radiations originated from the sun.</span>
Hi! I can help you out.
RNA polymerase binds to regions of DNA called promoters, which are "start" signals for transcription
The mantle is a layer inside a planetary bodybounded below by a core and above by a crust. Mantles are either made of rock or ices, and are generally the largest and most massive layer of the planetary body. Mantles are characteristic of planetary bodies that have undergone differentiation by density. The mantle is bounded on the bottom by the planetary core and on top by the crust. In addition to the Earth, the other terrestrial planets, a number of asteroids, and moonshave mantles.
