Answer:

Explanation:

Control over nitrogenase activity is accomplished by NH4+ prevents expression of the genes that encode nitrogenas.

Nitrogenase synthesis in free-living N2-fixing bacteria is universally under repressor control by ammonia. This, however, is not

the case for rhizobia. A need for N2 as inducer apparently does not

exist. The degree of ammonia repression is unusual in its strength.

Nitrogenase activity is at least 1O,OOO-fold lower in extracts of

NH4+-grown cells versus N2-grown cells.

Mr. Summers observed that kids with hot dogs are happy. This observation led to a hypothesis that hot dogs must make kids happy.

Maslowich

Given what we know, we can confirm that since Mr. Summers has to test a hypothesis, his next step should be to design an experiment.

<h3>Why design an Experiment?</h3>

The next step is to design an experiment.
This is because Mr. Summers has already made an observation and created a problem.
He must now gather data to be analyzed.
In order to do this, he must first design and perform an experiment.

Therefore, we can confirm that Mr. Summers must design an experiment given that this is the best way to gather data in order to be analyzed in the future and draw a valid conclusion.
