How are cells able to produce all of the different proteins that they need to survive

Cells are able to produce proteins from their DNA. DNA essentially contains the information for making a protein.

RNA (aka messenger RNA) carries the "codes" to making a protein out of the nucleus into the cytoplasm.

Once in the cytoplasm, tRNA (transfer RNA) deliver amino acids to the ribosome, where the form amino acid chains. These amino acid chains form together to make a protein.

Hope I helped! :)

answer : haversian

[explanation: -(compact bone is organized as parallel columns, known as haversian systems, which run lengthwise down the axis of long bones. these columns are composed of lamellae, concentric rings of bone, surrounding a central channel, or haversian canal, that contains the nerves, blood vessels, and lymphatic system of the bone)]
