Answer: The correct answer is B) Superconductor, conductor, semiconductor, insulator.
Resistivity to the flow of electrons is inversely related to the conductivity of the material. This means that more is the resistivity, lesser is the conductivity.
Superconductors are those materials, which have zero resistivity. Thus, they have maximum conductivity, conductors are those that have little resistivity, semiconductors have more resistivity than conductors, and insulators have maximum resistivity so they do not allow the electric current to pass through them.
Thus, B) is the right answer.
Febrile seizures are those that occur in young children during a particularly high fever. While these are usually harmless, they are frightening. The child should be seen by a doctor to rule out other causes.
The theory of common descent states that all living organisms are descendants of a single ancestor. Phylogenetic trees and cladograms are often used to hypothesize the evolution of various organisms and shared common descent.
