RNA molecules attach to codons when the ribosome reaches the start codon.
Explanation:
The start codon initiates translation of the mRNA by the ribosome into a polypeptide. When the ribosome finds the start codon, it attaches to the mRNA and the first amino acid, methionine, is recruited. The ribosome then continues translating the rest of the mRNA until it encounters a stop codon that initiates the ‘knocking off of the ribosome from the mRNA.

Cell membrane protects animals cells from harmful chemicals.
Explanation:
The cell membrane is a tough covering composed of the phospholipids and proteins and forms a bilayer around the cells. This acts as a semi-permeable membrane and controls the transport of ions, organic molecules and solutes to and from the cell through selective permeability.
The hydrophilic and hydrophobic properties and the corresponding polarity of the cell membrane and ionization status of the chemicals prevent the entry of harmful substances into the cell. The cell membrane functions as a barrier system and prevents the flow.
Answer: a hard sedimentary rock, composed mainly of calcium carbonate or dolomite, used as building material and in the making of cement.
