Sensory receptors that are sensitive to chemicals are found in the nose and mouth. While chemicals can have a reaction on other parts of the body, the receptors located in the nose and mouth are capable of recognizing these sensations the most.
Chemoreceptors are sensitive to changes in the concentration of chemicals

A common-sense glance at your question answers it. If something is poisonous, you're going to want to keep it well away from stuff that you eat. It just makes sense.
Odor is a human sense (or an animal sense), if you lack the organs for detecting it, then a substance is "odorless" ... to you. Note that (for us mammals) a substance must be in vapor form to be detected, thus solids lack odor in general, while heating intensifies odor.
Lots of chemicals store chemical energy. I don't believe that any single chemical is outstanding, not in the sense of storing several times the energy of the "next-best energy saver". Living beings use ATP for short-term energy storage, glucose for long-term energy storage.
A 'CHEMIST'. Similarly, A PHYSICIST for physics A BIOLOGIST for biology A MATHEMATICIAN for mathematics (Maths.).
a monarch butterflies special sense would be its antennae which at the tip of them has highly sensitive smell receptors. That can pick up traces of chemicals that human nose cannot detect.
Gustatory receptors are found on the tongue and pharynx and are taste receptors. They sense particles of foodstuffs dissolved in saliva and provide us with the sense of taste.
Yes.
Receptors
sensory receptors - specialized nerve cells
General sense organs consist of microscopic receptors widely distributed throughout the body in the skin, muscles, tendons, joints, and other internal organs of the body.
stimulus sense organs light eyes heat skin touch skin chemicals tongue sound ears pain skin and internal organs chemicals in the air nose
There are many sense organs in the body like touch receptors, pressure receptors, heart receptors, taste receptors, sound receptors, etc. All these receptors when stimulated result in changes in tone or isometric contraction of skeletal muscles around them or in the entire body.Sensation:Sensation is the observation of change in tone of skeletal muscles induced by a single sense organ.Thus, heat, sound, etc are sensations.Feeling:Feeling is the observation of changes in tone of skeletal muscles induced by many sense organs or continuous changes in a single sense organ.Thus, coffee induces a feeling and so does a song.
Gustatory receptors are also present in the mouths of animals. These are novel proteins which are able to recognize a variety of chemicals.

The special cells of the sense organs that receive stimuli from the environment are called receptors. The receptors detect different changes in the surrounding envronment and stimulate the neurons to perform the proper tasks.
The olfactory receptors are found in the olfactory epithelium in the upper portion of the nose. The sense is highly sensitive and easily fatigued. Information travels to your brain for storage, interpretation and memory.
