<h3>1: State the issue or problem that Fleming investigated.</h3>
he investigated the contamination of a fungus that produced antibiotic substances
<h3> 2 What was Fleming's hypothesis?</h3>
That the fungus produced antibiotics and inhibited the growth of bacteria
<h3>3 How was the hypothesis tested?</h3>
He made a nutritive broth, where he placed the fungus, after growth, he extracts the substances
<h3>4 Write a statement that summarizes the results of the experiment.</h3>
He discovered that antagonistic microorganisms may have biochemical devices, such as the production of antibiotic substances, in order to survive.
<h3>5 The Lear experiment for the development of what major medical breakthrough?</h3>
Yes, after this discovery millions of people did not die from bacterial infections.
With this information, we can conclude that Fleming performed several experiments concluding that the fungus Penicillium notatum had a substance capable of killing bacteria. This substance was called penicillin.
