This statement is false because the respiratory system includes  muscles that power your lungs. These muscles work together to move oxygen through your body and it cleans out waste like carbon dioxide.

The respiratory system also allows us to speak and smell. So we clearly need all of the organs in our respiratory system.

In which step of protein synthesis does the rRNA make protein?
Inessa [10]

Answer:

Translation is the second part of the central dogma of molecular biology: RNA → Protein. It is the process in which the genetic code in mRNA is read to make a protein. Translation is illustrated in the diagram below. After mRNA leaves the nucleus, it moves to a ribosome, which consists of rRNA and proteins.

Explanation:

Within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis — the stitching together of amino acids to make a protein molecule. In fact, rRNA is sometimes called a ribozyme or catalytic RNA to reflect this function.
