Emission Spectrum
Absorption has different roles. Absorption of greenhouse gases is very important.
This will heat the skin up.
photoelectric effect
The effect of it is so that the person doing the experiment knows exactly if the chemical is acidic or alkeline.

the more ionized the drug is the less absorption
Control in science is something that can be used for comparison to determine the magnitude of an experimental effect. For example in a control group either nothing is done or a fake version of the experiment is performed to determine a "baseline". The results of the control experiment and the real experiment can be compared. This process helps eliminate the experimenter expectations effect, making the conclusions more objective. Note: controls are rarely needed outside the field of biology.
An experiment Apex:)
A high fat meal will slow the absorption of alcohol.
Caffeine: Caffeine has a small effect on calcium absorption. It can temporarily increase calcium excretion and may modestly decrease calcium absorption, an effect easily offset by increasing calcium consumption in the diet.
In an experiment, your control variable will not be caused to vary by the experiment. Think of 'cause and effect'. The independent variable is the cause, the result is the effect, and the dependent variable is the one that you leave to be changed by the experiment.
