The table below summarizes the effect of commercial fishing on a local Atlantic cod population over an 9-year period. Based on the data in the table, which conclusion is valid?
The number of fishing boats has les effect on the local cod population than pollution
More fishing boats make the cod population estimates more accurate

SpongeBob noticed that his favorite pants were not as clean as they used to be. His friend Sandy told him that he should try using Clean-O detergent, a new laundry soap she found at Sail-Mart. SpongeBob made sure to wash one pair of pants in plain water and another pair in water with the Clean-O detergent. After washing both pairs of pants a total of three times, the pants washed in the Clean –O detergent did not appear to be any cleaner that the pants washed in plain water. What is the control in this experiment?
Type of detergent
Pants washed in Clean-O detergent
Pants washed in plain water
Water
SpongeBob noticed that his favorite pants were not as clean as they used to be. His friend Sandy told him that he should try using Clean-O detergent, a new laundry soap she found at Sail-Mart. SpongeBob made sure to wash one pair of pants in plain water and another pair in water with the Clean-O detergent. After washing both pairs of pants a total of three times, the pants washed in the Clean–O detergent did not appear to be any cleaner that the pants washed in plain water. What is the INDEPENDENT variable in this experiment?
