DNA, ribosomes, plasma membrane and cytoplasm are the structures that are found in both.
Explanation:
Prokaryotes are the organisms that do not have a nucleus and other membrane-bound organelles and eukaryotes have a membrane-bound nucleus and another membrane-bound organelle.
Apart from this there are some similarities between prokaryotic and eukaryotic cell like both have a highly selective cell membrane, they both have cytoplasm, both have DNA and ribosomes which is responsible for the expression of genes. Therefore DNA, ribosomes, plasma membrane, and cytoplasm are the structures that are common in both prokaryotes and eukaryotes.
I think the correct answer from the choices listed above is option A. If the reaction of maltase is optimum at the pH range of 6 to 7, then most likely when the ph is decreased into three maltase would not be able to function outside of its optimal pH range. Hope this answers the question.
The cell membrane consists of a lipid bi-layer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.
