Students places equal amounts of bacteria on fifteen identical agar plates containing the same amounts and types of nutrients. Five of the plater were kept at 0Β°C, five were kept at 45Β°C, and five were kept at 22Β°C (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 plates determines the temperature of the bacteria.
D) The temperature of bacteria is determined by the bacteria' growth
