Question

What controlled experiment could be conducted to test the hypothesis?

A) Setting the light at 12 hours/day and temperature at 25 degrees Celsius, testing the rate of 1 drop/hr.
B) Setting the light at 8 hours/day and temperature at 30 degrees Celsius, testing the rate of 5 drops/hr.
C) Setting the light at 10 hours/day and temperature at 20 degrees Celsius, testing the rate of 10 drops/hr.
D) Setting the light at 24 hours/day and temperature at 15 degrees Celsius, testing the rate of 3 drops/hr.
E) Setting the light at 6 hours/day and temperature at 35 degrees Celsius, testing the rate of 8 drops/hr.

Answer 1

The controlled experiment used to test the hypothesis is setting the light at 10 hours/day and temperature at 20 degrees Celsius and measuring the rate of 10 drops/hr.

Step-by-step explanation:

The controlled experiment that could be conducted to test the hypothesis is option C: Setting the light at 10 hours/day and temperature at 20 degrees Celsius, testing the rate of 10 drops/hr.

In this experiment, the independent variable is the light duration and temperature, while the dependent variable is the rate of drops. Other variables, such as the number of seeds, moisture level, and type of seeds, should be kept constant.

This experiment allows for testing the hypothesis by manipulating the factors affecting the rate of drops to determine the relationship between light duration and temperature on the rate of drops.
