The triclinic shape of copper sulfate can be seen in this cluster of crystals. Copper sulfate crystals are somewhat strange. Some crystals can hold their color for years with no change, while others dehydrate and turn into a white powder. This crystal of copper sulfate is nearly twenty years old.ne of the very best chemicals for growing crystals is copper sulfate. The only trouble with it is that is a poisonous chemical compound. Because of its poisonous nature, it has been used to kill tree roots in sewers. A solution of copper sulfate is simply flushed down the toilet to kill tree roots.
A sensory system is a part of nervous system consisting of sensory receptors that receive stimuli from internal and external environment, neural pathways that conduct this information to brain and parts of brain that processes this information.
In a sensory system, a sensory receptor is a sensory nerve ending that responds to a stimulus in the internal or external environment of an organism. In response to stimuli, the sensory receptor initiates sensory transduction by creating graded potentials or action potentials in the same cell or in an adjacent one.he sensory receptors involved in taste and smell contain receptor molecules that bind to specific chemicals. Odor receptors in olfactory receptor neurons, for example, are activated by interacting with molecular structures on the odor molecule.
