The organelles that produce proteins used within the cell are the mitochondria lysosomes ribosomes centrioles

Option C. "Ribosomes"

Explanation:

The organelles responsible for the production of proteins within the cell are the ribosomes.

A ribosome is known as the protein synthesis site in the cell. Ribosome contains a large and a small subunit, each of which consists of ribosomal proteins and rRNA (ribosomal RNA). During protein synthesis the messenger RNA or mRNA moves through the ribosome and amino acids attached to transfer RNA or tRNAs comes to the ribosome. As a result, the amino acids joined to produce the protein.

Thus, the correct option is Ribososmes.

answer; both surfaces of the membrane are nonpermeable

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.
