Sponge Bob notices that his pal Gary is suffering from slimotosis, which occurs when the shell develops a nasty slime and gives off a horrible odor. His friend Patrick tells him that rubbing seaweed on the shell is the perfect cure, while Sandy says that rubbing Dr. Kelp's solution will be a better cure. Sponge Bob decides to test this cure by rubbing Gary with 5 milliliters of seaweed solution on half of his shell and rubbing 5 milliliters of Dr. Kelp's solution on the other half of Gary's shell. What is the control variable? O the type of solution O the absence of slimotosis O the same amount of solution used on both halves of the shell
