two magnifying lenses. It produces two dimensional image. The eyepieces and the objective lenses give a very high magnification, a condenser that is below the stage focus the light into the specimen to be viewed.
Dependent and Independent variables are regarded as variables in mathematical and statistical modeling and of course in some other aspects.
The independent variable is this case is the amount of salt.
- In this kind of scenario, one can think of independent and dependent variables in terms of cause and effect.
- An independent variable is the variable we assume to be the cause, while a dependent variable is assumed as the effect.
- Therefore, with this case, the amount of salt would cause a decrease in the number of plants.
- While the effect of increasing the amount of salt would be seen in the number of plants.
