Single celled organisms are able to maintain homeostasis, withstanding relatively large alterations in their external environments . This is due to the fact that they posses structures that regulate and carry out life functions. They perform all the functions that are necessary for an organism to exist.
The ability to obtain all the substances that are essential for their existence eliminates the need for dependence on other cells. These single-celled organisms are thus able to maintain a relative state of equilibrium within their internal environment.
When a person watches television for a long stretch of time in order to observe and then, record the total aggressive incidents occurring during that period is a good example of the rate measure of the behavior. The rate measure refers to the measure of the frequency of the concerned events occurring in the defined period of time. Since, the person is looking for the aggressive behavior on television during his four hour watching, this is a rate measure.
All the things that we can sense have their origins in the PERIPHERAL NERVOUS SYSTEM.
The peripheral nervous system is made up of all the nerves that are located outside the spinal cord. These nerves transport information to and from the central nervous system. The sensory cells are involved in carrying information from the peripheral nervous system to the central nervous system. The sensory cells include the cells that are responsible for sight, sound, smell, taste and pressure.<span />
