A scientist would like to test the effect of heat on the function of a certain enzyme. Which would not be an appropriate first step?

(1) doing research in a library (2) having discussions with other scientists (3) completing a data table of expected results (4) using what is already known about the enzyme

(3) completing a data table of expected results

Explanation:

Observation and research of the available literature about the process under study are some of the tasks done before experimentation. The data table of expected results is not to be made before any research.

Research and discussion on the basic information about the enzyme under study, the search of any experiments done on the same enzyme earlier gives insight about the enzyme. This is followed by making a hypothesis and setting the experiment to test the hypothesis.
