An elastomer is a polymer with viscoelasticity which have low youngs modulus with weak intermolecular forces when compared with other materials.

The combined gas law states that the ratio between the pressure-volume product and the temperature of a system remains constant.

Hence it depends on all the three Volume, Temperature & Pressure.

Agriculture would be a good example of a purely competitive industry.

Resistivity :

Resistivity is a measure of the resistance to the flow of electrons. 

Conductivity :

Conductivity is just the inverse of resistivity, σ = 1/ρ, where σ is conductivity and ρ is resistivity.

Example:

Think of a pipe and water, the bigger the pipe, the easier water can flow and thus the lower the resistance. 

The process of copying dna is called Replication.

The second would employ a comma, or semi-colon, and not a colon so it is not properly punctuated.

The third sentence would not be correct because it uses 'like', usually used for comparison. Since you are not comparing two questions, it would not be appropriate.

The fourth sentence has 'is' before the colon, which is a implies declaration and not listing. So, again, it would not be appropriate.

Hence, the first sentence, however, is punctuated correctly.
