membrane changes its electric potential. In other words‚ how is the cell membrane excited? At the surface of the cell membrane‚ there are three classes of gated channels exist‚ chemically gated or ligand-gated channels‚ voltage-gated channels‚ and mechanically gated channels. Originally‚ at the resting membrane potential‚ most of the gated channels are closed. However‚ when these gated channels open‚ the movement of ions across the membrane will changes the membrane potential. In the nervous system‚ the

Types of Variable A variable is any factor‚ trait‚ or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent‚ dependent‚ and controlled. Dependent and Independent Variables Independent variable The independent variable is the one that is changed by the scientist. To insure a fair test‚ a good experiment has only one independent variable. As the scientist changes the independent variable‚ he

Telemedicine is the use of medical information exchanged from one site to another via electronic communications to improve a patient’s clinical health status. Telemedicine includes a growing variety of applications and services using two-way video‚ email‚ smart phones‚ wireless tools and other forms of telecommunications technology. I believe this is a great way for doctors‚ dentist‚ and any other health care professional to easily get the information that they need quickly. This is a huge time

The Neuron Doctrine is a concept that led scientists to the realization that the brain consists of many specialized regions and cells. However‚ during the process‚ scientists had to overcome obstacles such as the minute size of the cell‚ the jello-like consistency of brain tissue‚ and the similar cream- colored pigmentation of tissue cells. Advances in technology over the years‚ though‚ helped to solve these problems: the development of the compound microscope‚ the discovery of how to harden‚ or

Explain the concept of potential output and why actual output can differ from potential output? (2 marks) Potential output is the amount of output that an economy can produce when using its resources such as capital and labour‚ at normal rates. Potential output is not a fixed number but grows over time‚ reflecting increases in both the amounts of available capital and labour and their productivity. As capital and labour can be utilised at greater than normal rates‚ at least for a time‚
