Solution to example 2. 1  multiply all terms in the first equation by 2. 2  add the two equations. 3  Conclusion: Because there are no values of x and y for which 0x + 0y = 11, the given system of equations has no solutions.
Baroreceptors (or archaically, pressoreceptors or baroceptors) are sensors located in the blood vessels of all vertebrate animals.hey sense the blood pressure and relay the information to the brain, so that a proper blood pressure can be maintained. Baroreceptors are a type of mechanoreceptor sensory neuron that is excited by stretch of the blood vessel.
Insect hearing receptors are typically located on the legs, and sometimes on the body, of the insect. In crickets, the ear is located on the tibia of the foreleg. The eardrum of crickets is called a tympanum, and consists of an oval membrane on one side of the leg, and a smaller round tympanum on the other surface.
