A: Animals use their perception of smell (olfaction) for various activities like finding mates,…

Q: Describe the parts of the external, middle, and internal ear, and the receptors they contain, and…

A: The ear is a sensory organ present in pairs and is involved in two primary functions - hearing and…

Q: What is the function of Color Vision?

A: The visual sense organ is comprised of the eyes. The eyes are made up of multiple components and are…

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.
