An investigation was carried out to determine which of three antibacterial soaps is most effective. Four petri dishes labeled A,
B, C, and D were set up. The same amount and type of bacteria was added to each dish. Next, 2 mL of a different brand of soap were added to dishes B, C, and D. Then, 2 mL of water were added to dish A, instead of soap. The dishes were incubated at 37°C for 24 hours. At the end of the investigation, the amount of bacteria in each dish was determined. Dish D had the least bacteria. It was concluded that the soap in dish D was the most effective soap to use against bacteria. Which statement best describes the validity of this conclusion?
More carbon would be released into the air with the burning of more fossil fuels and the environment would not be able to process the extra carbon.<span />
