Answer:
organelles are very similar to present-day bacteria, suggesting a common ancestor.
Explanation:
Some evidence suggests that some organelles like mitochondria and chloroplasts within eukaryotes were once used to be independent eukaryotes.
Endosymbiosis theory says that ancestral prokaryotic cells engulfed bacteria like cyanobacteria which with time evolved into mitochondria and chloroplast. Molecular evidence also proves that these organelles were once prokaryotic organisms because they show similar genetic makeup and ribosome type.
So these organelles are similar to present-day bacteria showing that they have a common ancestor.

When Amanda poured some of the liquid in a test tube, she noticed that the edges if the water curved upward, which is an illustration of adhesion.
When Pol filled another test tube to the top, the liquid formed a low dome, which is a proof of cohesion.
When Amanda added table salt to the first test tube and shook it, she noticed that the liquid had dissolved the solute.
All of these observations are suggesting the existence of covalent bonds.
Pol determined that the pH of the sample is 7 that indicates that the sample is neutral.
Based on all the proof gathered by Pol and Amanda, the unknown liquid is water.
