<h2>
Answer</h2>
Three types of covalent bonds, they can form
<h2>
Explanation</h2>
Carbon has four valence electrons in the outer shell but it forms three covalent bonds with another carbon atom. i.e Single bond, double bond and triple bond.
- The single bond is called Alkanes e.g. Methane, Propane etc.
- Double bonds are called alkenes e.g. Ethylene, Propylene etc.
- Triple bonds are called alkynes e.g. Ethyne, Propyne, Butyne etc.
A vascular plant is a plant that is characterized by the presence of conducting tissue.
A shell is considered as biotic (living) because it is a hard, rigid covering of many animals such as snail, sepia, pila, turtles, sea urchins. A shell is protective outer layer of these soft bodied animals.

Answer:
The correct answer will be option-is read by ribosomes during the process of translation.
Explanation:
The DNA is a nucleic acid made up of nucleotides which serves as a genetic material of the cell. It stores the information required by the cell in the form of codons made up of nitrogenous bases. The DNA after transcription forms a messenger molecule called mRNA which is read by the ribosomes to code for specific amino acid which binds to form the proteins, the building block of the body.
Since the mRNA is read by the ribosomes during translation and not DNA directly, therefore, the selected option is the correct answer.
