Students placed equal amounts of bacteria on fifteen identical agar plates containing the same amounts and types of nutrients. Five of the plates were kept at 0ºC, five were kept at 45ºC, and five were kept at 22ºC (room temperature). Which of the following was probably the hypothesis for this experiment? A. The growth of bacteria increases as temperature increases. B. The type of nutrient causes bacteria to grow faster at higher temperatures. C. The size of the plates determines the temperature of the bacteria. D. The temperature of bacteria is determined by the bacteria's growth.

A would be the correct answer.

The temperature is going up thus creating the theory that bacteria grows faster in higher temperatures or lower temperatures.
