Answer:

D) There are two major subunits, each with multiple proteins.

Explanation:

The ribosome is a complex structure made of RNA and proteins. Both prokaryotic and eukaryotic ribosomes have two subunits: small and large subunits. Each of these subunits is made of specific types of ribosomal RNAs (rRNA) and a number of different proteins.

For example, the 30S subunit of <em>E. coli</em> ribosome has 21 different proteins while its 50S subunit is made of 33 different types of proteins along with rRNA.

Likewise, the 40S subunit of a eukaryotic ribosome is made of 33 proteins while its 60S subunit has 47 proteins. The eukaryotic ribosome contains a total of 80 different proteins.

The papillary muscles contract after the other ventricular muscles so that they can take up the slack on the chordae tendineae b

sashaice [31]

Answer:

False

Explanation:

The papillary muscles of both right and left ventricles began to contract shortly before the other ventricular muscles (systole) so that they can take up the slack on the chordae tendineae as the full force of ventricular contractions sends blood against the atrioventricular (AV) valve flaps.

They prevent the backward flow of blood to atria from ventricles. So if they contract after the ventricle systole they would not be able to perform their job.
