Some students grew sunflower plants. The following table and graph shows the conditions and results of the experiment after three weeks. Use this information to answer the following questions.
(I put an image of the table and graph above)

1. Was this a controlled experiment? Explain.

2. State a possible hypothesis for this experiment. Independent Variable: Dependent Variable:

3. Which plants are the experimental subjects?

4. Which plant is the control subject.

5. What are the controlled variables? (List three)

Plant A, Plant B are the experimental subjects

Plant C is the control subject

The controlled variables are Temperature, Humidity and Water

Explanation:

As mentioned in the question the whole procedure is an experimental set-up where experiments are being done to test the growing condition of plants under a controlled environment. The various parameters such as Temperature, Humidity, Water, Light and colour of light are fixed. Following these controlled conditions different plants exhibit different growth after a period of three weeks.

3). The Plants which are experimental subjects are Plant A, plant B, Plant C

4).Plant C is the control subject since it is kept in the ordinary light conditons (i.e. white light)

5). The Controlled variables include Temperature, Humidity and Water content.

the correct answer is sex-linked recessive.

i just took the test

voluntary muscles are controlled by the cerebellum.
