DRAW IT The reflex that pulls your hand away when you prickyour finger on a sharp object relies on a neuronal circuit withtwo synapses in the spinal cord. (a) Using a circle to represent across section of the spinal cord, draw the circuit. Label the typesof neurons, the direction of information flow in each, and thelocations of synapses.

Communication

Communication is a method of transferring information between two persons or organisms. Communication is possible using mutually understood behaviors such as signs, symbols, or language. In the year 1980, S. F. Scudder proposed communication theory. According to his ideas, all living beings on the earth communicate, but the methods of communication differ. Communication skills are now part of soft skills.
