What were the results of Fleming's

Biology
1 answer:
astra-53 [7]4 years ago
7 0

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 <em>Penicillium</em>. He said that (quote)<em> "...at a considerable distance around the fungus, the growth of  Staphylococcus colonies were suffering  lysis ..." </em>
  • 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) "...<em>What had previously been a  well-formed colony, it was now  a faint shadow of its former form...". </em>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.

Evidence that supports the prokaryotic origins of mitochondria and chloroplasts are all of the following except __________.
hodyreva [135]

Your question was incomplete (please check below the full content). The evidence that supports the prokaryotic origins of mitochondria and chloroplasts do not include multiple DNA copies associated with inner membranes.

<h3>What is organellar DNA?</h3>

The organellar DNA is the genome contained within mitochondria and chloroplasts, which is independent of nuclear eukaryotic DNA.

The organellar DNA contains multiple DNA molecules, which are found in association with the inner membrane, ant is not found in prokaryotic life forms.

The complete question in this case is: "Evidence that supports the prokaryotic origins of mitochondria and chloroplasts are the presence of mitochondria, a eukaryote engulfing prokaryotic photosynthetic cells, and non-photosynthetic eukaryotes, EXCEPT."

The endosymbiotic theory states that mitochondria and chloroplasts evolved from prokaryotic microorganisms that entered into a primitive eukaryotic cell.

This theory is supported by certain features of mitochondria and chloroplasts such as a similar size to prokaryotes.

In conclusion, evidence do not include the arrangement of the organellar DNA.
