The correct terms to fill in the blanks would be contracts and dilates. In stressful situations, the sympathetic nervous system contracts the arteries of the circulatory system resulting to the dilation of the pupils of the eyes. Also, during these situations, the blood sugar levels are raised since the hormones for stress kick in to combat the stress which in turn raises the blood sugar.

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?

Describe what you think is happening during photosynthesis.
sineoko [7]
<h2>Answer:</h2>

<em>I think during photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.</em>
