The hypothesis which most likely explains the results is The enzyme breaks down at temperatures above 60°C; option B.
<h3>What are enzymes?</h3>
Enzymes are biological catalysts which speed up the rate of chemical reactions that occur in the body.
Enzyme activity is affected by the following factors:
- temperature
- pH of the medium
The temperature at which enzyme works best is known as optimum temperature.
The pH at which enzyme works best is known as optimum pH.
Considering the results of the experiment as shown in the graph:
The activity of the enzyme decreases to zero at 60°C.
Therefore, the hypothesis which most likely explains the results is The enzyme breaks down at temperatures above 60°C; option B.
In conclusion, enzymes are denatured by high temperatures.

Answer:
The correct answer would be "Adaptive radiation happens over a relatively short time".
Adaptive radiation refers to the process of evolution in which ancestor organisms diversify rapidly into a wide variety or new forms as a result of environmental changes, availability of new resources, availability of new niches, or new challenges.
Accumulation of adaptive radiations over a long period of time results in speciation.
For example, Darwin's finches adapted according to their feeding behavior.
