Question

Sponge bob notices that his pal Gary is suffering from slimotosis, which occurs when the shell develops a nasty slime and horrible odour. His friend Patrick tells him that rubbing seaweed on the shell is the perfect cure, while Sandy says that drinking Dr. Kelp will be a better cure. Sponge Bob decides to test this cure by rubbing Gary with seaweed for a week and having him drink Dr. Kelp at the same time. After a week of treatment, the slime is gone and Gary's shell smells better. What is the control in this experiment?

1. There is no control
2. Dr. Kelo
3. Seaweed
4. Gary

Answer 1

IIn experimental design, having a control group is crucial for making meaningful comparisons and drawing valid conclusions. In this case, Gary's original condition before any treatment serves as the control. the correct option is (4).

Step-by-step explanation:

In this experiment, Gary serves as the control. A control is the baseline or reference group that does not receive the experimental treatment. In this case, SpongeBob is testing the effectiveness of two treatments—rubbing Gary with seaweed and having him drink Dr. Kelp. Gary, who undergoes both treatments, serves as the control because SpongeBob can compare the changes in Gary's condition to his original state.

Options:

There is no control: This statement is incorrect because Gary, the untreated state, serves as the control in this experiment.

Dr. Kelp: Dr. Kelp is one of the experimental treatments, not the control.

Seaweed: Seaweed is another experimental treatment, not the control.

Gary: Gary, being the untreated state, is the control in this experiment.

In experimental design, having a control group is crucial for making meaningful comparisons and drawing valid conclusions. In this case, Gary's original condition before any treatment serves as the control.
