A student wants to test the effect of temperature on the growth of bacteria. They set up an experiment where they grow two groups of bacteria, one group at a temperature of 25°C and another group at a temperature of 37°C. The student counts the number of colony-forming units every hour for six hours. They use the same type and amount of nutrient media for both groups of bacteria.
What is the research question for this experiment?

Multiple Choice
A student investigated the effect of the presence of four different molecules, R, S, T and U, on the rate of cellular respiration in human liver cells. The production of carbon dioxide by the cells was recorded over a five-minute interval. The final concentration of carbon dioxide was recorded. The data collected is shown to the left.
The student presented the results as a graph. Which one of the following graphs is the best representation of the results?
