the old factory bulb located in the front of the brain. It relays that sensation into the pariatal lobe(im not too sure about the spelling), which processes senses
chemoreceptors
neuroepithelia
Some gases have no odor. Air and its normal constituents are odorless. Since smell, odor, is sensed from gases, any liquid or gas that does not give off any gas will be odorless as well.
Taste is sensed through taste buds on the tongue; these organs respond to crude measures of taste including sweet, salty, sour and bitter. Fine-tuning of the taste is actually accomplished through the olfactory bulbs of the nose, which are responsible for the sense of smell.
Corndogs smell for the same reason any other thing smells. Tiny particles on the corndog are constantly being released into the air. Heating a corndog will accelerate the process and may cause a stronger smell.
chemoreceptors
Sweet, sour, salty, bitter and umami (before also called savory) are the 5 basic taste sensation that are sensed by the taste buds in the tongue. However a great part of real taste perceptions are a combination with smell sensations from the nose. Also a certain part is psychologically determined.
This is a silly question. Smell is a sense of a living thing. To smell, you need a living thing. There was no Godly beginning, evolution was the way, so when noses were developed, smell was sensed.
The antenna are the main organs of the sense of smell. One of the main odors sensed are sex pheromones.

Not much except they are all sensed by humans through different receptors. The smell of rotten eggs are created by the sulfur-containing compounds released during the decomposition of eggs and are sensed by chemoreceptors in the nose. Heat is a transfer of energy from hot to cold objects and can be done by contact, convection or radiation, but it is invariably sensed by thermoreceptors in the skin. Light's precise nature is a duality of particle (photon) and wave (EM radiation) which cannot be described by conventional means but it is perceived by photoreceptor cells in the eye.
smell travels in the air in a process called diffusion.
