聽日test bio急急急!!

controlled variables
控制变量
dependent variable
因变量
independent variable
独立可变物

our teacher teach this very well.
let me share our teacher explanation:
let take a case as an example
rate of reation of enzyme depend on temperature.
that means temperature will affect the rate of reation of enzyme
so rate of reation depends on temperature.
SO,rate of reaction is dependent variable.
temperature is indenpendent variable.
SO,control variable means it is neccessary to control this factor to prevent the possible error occur.

controlled variables, 受控變量
dependent variable, 因變量
independent variable, 獨立變量

controlled variables 受控可變物
dependent variable 變量可變物
independent variable 獨立可變物

controlled variables=受控變量
dependent variable=因變量
independent variable=獨立變量

I hope I can help you la=]
