Me answer the following questions. 1. give 2 examples of hypotheses that you could test by conducting a controlled experiment. 2. a student hypothesizes that exercise will increase clothespin squeezing rate. what is the dependent variable? what is the independent variable? what other variables should be kept constant? 3. a student hypothesizes that eating pizza will increase test scores? what is the dependent variable? what is the independent variable? what other variables should be kept constant? ~ you for the .

1. I answered that earlier.

2. -Dependent Variable (Variable affected by change): Clothespin squeezing rate

-Independent Variable (What is changed): amount of exercise

-Constant: Type of exercise and Type of clothespins

3. -Dependent Variable (Variabled affected by change): Test Scores

-Independent Variable (What is changed): What they eat (Pizza)

-Constant: Type of pizza and Type of test

B

Explanation:

Photosynthesis uses CO2 and water to make oxygen and glucose.

6CO2 + 6H2O → C6H12O6 + 6O2 This is the chemical reaction that occurs. Products are on the right and we can see glucose and oxygen are formed.
