state. Using a given chemical substance, which is the dibromoethane,
we can simply find out the relationship between those three gas laws.
The relationship are shown through 8 graphs plotted based on fixed
properties of dibromoethane such as critical temperature, pressure,
saturated liquid and vapor volume as well as using the general formulas
of the three gas laws. There are 7 gra

Ion channels ion-selective and fluctuate between open and closed states
The membrane potential in animal cells depends mainly on K⁺ leak channels and the K⁺ gradient across the plasma membrane
The resting potential decays only slowly when the Na⁺- K⁺ pump is stopped
The three-dimensional structure of a bacterial K⁺ channel shows how an ion channel can wo

Under capitalism, man exploits man; under communism, it is opposite.
☞ The key goal of the communist movement
The abolition of private ownership of the ‘means of production’ such as factories and machines.
☞ Why?
They believed that it was the reason for the ‘wasteful’ anarchy of the market.
However…..

(1) 사염화탄소란?
사염화탄소는 인간이 만든 무색투명한 액체로 강하고 달콤한 향을 띄며 클로로포름과 같은 향을 갖는다. 사염화탄소는 VOC(Volatile organic compound)에 속하며 휘발성이 강하다.
