ANSWER: compared to PH3 a PH1 would be more acidic than a PH3
Explanation: so on the PH scale 1 is acid 7 is neutral and 14 is alkaline. PH1 would be stomach acid, a PH3 would be vinegar.
They are considered organic molecules because the monomer which make proteins are amino acids which are organic compounds.

The difference between a hot spot volcano and the volcanoes from Ring of Fire can mainly be seen in the way of formation and functioning. The hot spot volcanoes are far away from any tectonic plate boundary and they manage to penetrate the crust over them and come out on the surface to usually create volcanic islands. The activity of the volcanoes from the Ring of Fire depends directly from the activity between the bordering tectonic plates, and as the borders move over time, the volcanoes stop existing, and new ones rise in the direction where the boundary moves.
The similarity can be seen in the type of eruptions, and that usually both types of volcanoes form volcanic islands.
Example for a hot spot volcano is Mauna Loa on Hawaii.
The right answer is the lysosome
The lysosome is a eukaryotic cell organelle.
The lysosome contains hydrolases, enzymes intended for the degradation of intracellular molecules. They are only active at acidic pH, hence the lowering of the pH in the vesicle.
The lysosome has a cellular garbage function, where the non-functional or undesired molecules are removed by digestion.
