Experimental Group DefinitionExamples of Experimental GroupRelated Biology TermsQuiz
In a comparative experiment, the experimental group (aka the treatment group) is the group being tested for a reaction to a change in the variable. There may be experimental groups in a study, each testing a different level or amount of the variable. The other type of group, the control group, can show the effects of the variable by having a set am...

The soil is the topmost layer of the earth’s crust mainly composed of organic minerals and rock particles that support life. A soil profile is a vertical cross-section of the soil, made of layers running parallel to the surface. These layers are known as soil horizons. The soil is arranged in layers or horizons during its formation.احصل على السعر
