Answer:
superconductor
- noun: superconductor; plural noun: superconductors a substance capable of becoming superconducting at sufficiently low temperatures. a substance in the superconducting state. "as they are cooled through a critical temperature, they suddenly become superconductors"
insulator- noun: insulator; plural noun: insulators
a substance which does not readily allow the passage of heat or sound. "cotton is a poor insulator" a substance or device which does not readily conduct electricity. a block of material, typically glass or ceramic, enclosing a wire carrying an electric current where it crosses a support.
conductor- noun: conductor; plural noun: conductors 1. a person who directs the performance of an orchestra or choir. "he was appointed principal conductor of the Berlin Philharmonic Orchestra" 2. BRITISH a person in charge of a train, streetcar, or other public conveyance, who collects fares and sells tickets. 3. PHYSICS a material or device that conducts or transmits heat, electricity, or sound, especially when regarded in terms of its capacity to do this. "graphite is a reasonably good conductor of electricity" another term for lightning rod.
semiconductor- noun: semiconductor; plural noun: semiconductors a solid substance that has a conductivity between that of an insulator and that of most metals, either due to the addition of an impurity or because of temperature effects. Devices made of semiconductors, notably silicon, are essential components of most electronic circuits.

Answer:
The correct answer is- olfactory nerve(1)
Explanation:
Olfactory nerve is the first nerve out of the 12 cranial nerve that is located in the head and is also the shortest of all the cranial nerve. The receptors of the olfactory nerve are present in the nasal mucosa that passes to the forebrain.
It pass sensory information of smell to the brain so it plays the sensory function in smell perception. The damage to olfactory nerves can lead to:
Anosmia: In anosmia, people lose their ability to smell.
Hyposmia: In this condition, the ability to smell gets reduced.
Dysosmia: In this situation, people lost their ability to distinguish between various types of smell.
So the right answer is olfactory nerve(1).
Darwin's proposed mechanism for evolution is natural selection. Natural selection allows species to respond to their surroundings through time, or to become progressively excellently-suited. Natural selection is environmentally based and involves established heritable variation within a population.
They lead to changes in species over time:
- Darwin suggested species will evolve over time, new species originate from pre-existing species, and all species share a common ancestor with each other.
- In this framework each organism has its own special set of heritable i.e genetic variations from the common ancestor that have slowly developed over very longer periods of time.
- Parroted branching activities that isolate new species from a common ancestor create a multi-level tree that connects all living organisms.
