Question

Which statement is a valid conclusion based on the information in the graph?


Select one:

a. Changes in temperature cause bacteria to adapt to form new species.

b. Individual species reproduce within a specific range of temperatures.

c. Increasing temperatures speed up bacterial reproduction.

d. Bacteria can survive only at temperatures between 0°C and 100°C.

Answer 1

The correct option is c)  Increasing temperatures speed up bacterial reproduction.

Explanation:

• As the diagram depicts, an increase in temperature increases the generations per hour.
• The generation per hour is the reproduction rate for the microorganism which is the bacteria here.
• As the temperature increases, the bacterial rate of generation also increases.
• Hence, option C is the correct option.

Answer 2

Explanation:

c. Increasing temperatures speed up bacterial reproduction.
