Question

1. what is the role of the cell membrane in both prokaryotic and eukaryotic cells?

protects the dna
produces energy
controls what goes in and out of the cell
makes proteins

Explanation:

• "Protects the DNA" is incorrect because the nucleus (in eukaryotes) or nucleoid region (in prokaryotes) is related to DNA protection, not the cell membrane.
• "Produces energy" is incorrect as energy production occurs in mitochondria (eukaryotes) or cell membrane - associated processes in some prokaryotes, but the main role of the cell membrane is not energy production.
• "Controls what goes in and out of the cell" is correct. The cell membrane is a selectively permeable barrier that regulates the passage of substances into and out of the cell, which is a fundamental role in both prokaryotic and eukaryotic cells.
• "Makes proteins" is incorrect as protein synthesis occurs at ribosomes.

Answer:

C. Controls what goes in and out of the cell (assuming the options are labeled A - D with "Controls what goes in and out of the cell" as option C; if the original options were labeled differently, adjust the label accordingly, e.g., if it's the third option, state the option text with its label as per the original question's numbering)
