experiment? Were his observations

qualitative data or quantitative data?

Answer using 2 to 3 complete

sentences.

Answer 1

Answer and Explanation:

• Results: After finding that a forgotten plaque, which was initially filled with Staphylococcus, had been contaminated by a fungus, Flemming noticed that the areas surrounding the fungus were free of Staphylococcus. His results were that the bacteria was destroyed by the fungus, which was identified as a Penicillium. He said that (quote) "...at a considerable distance around the fungus, the growth of Staphylococcus colonies were suffering lysis ..."

• His observations were qualitative, as he could just observe and describe what he was happening, but he did not perform any count quantities. In his descriptions, he said (quote) "...What had previously been a well-formed colony, it was now a faint shadow of its former form...". He described the situation as a previously well-formed colony, to a shadow of its former form. He characterized the colony but did not count the surviving or dead cells.
