Answer:
The correct answer is rRNA plays an important role during translation (protein synthesis) of mRNA.
Explanation:
Ribosomal RNA or rRNA are the RNA molecules which build up the site for protein synthesis known as ribosomes.
Ribosome synthesis takes place in nucleolus where two types of rRNA molecules associates with proteins, one in large subunit and one in the small subunit to form ribosomes.
These ribosomes physically moves along an mRNA molecule and catalyze the assembly of amino acids where rRNA molecules performs the catalytic steps of protein synthesis that is stitches amino acids together and makes up proteins.
Thus, rRNA plays an important role during translation (protein synthesis) of mRNA.
Answer:
Membrane bound cell organelles
Explanation:
A prokaryotic cell lacks a membrane defined nucleus and all the membrane-bound organelles. A eukaryotic cell has a membrane-bound nucleus and other membrane-bound organelles such as mitochondria, chloroplasts, endoplasmic reticulum, lysosomes, Golgi apparatus, etc.
To determine if a cell is a prokaryotic or eukaryotic, one can look for the nucleus and the membrane-bound organelles. If the cell has a nucleus and membrane-bound organelles, it is a eukaryotic cell. The absence of these structures makes it a prokaryotic cell.

Answer:
<em>Reversed polarity</em> is when the hot and neutral connections at a receptacle are wired backwards/inverse—Home wiring is color-coded, and the black wire is “hot,” meaning that it is electrically charged or, as it is sometimes called, the “live” wire!
Answer:
<u>Shrinking habitat because of habitat distruction,</u> is changing the geographic range of koalas. Because of this koalas are coming in contact with humans and domestic animals and getting hurt/killed while searching for food since there isn't enough in the wild.
