The one variable that is purposely changed to test a hypothesis is called?

The variable that the experimenter deliberately changes is called the independent variable. The thing you are observing as a result of the different 'values' or 'conditions' of the independent variable is called the dependent variable. If the experiment is well controlled, then you can have some confidence that changes in the dependent variable have come about directly as a result of your changes to the independent variable.


What are the experimental variables?

Experimental variables are factors being tested or measured in a scientific experiment. They can be categorized as independent variables (manipulated by the experimenter), dependent variables (respond to the changes in the independent variable), and controlled variables (kept constant to prevent interference).


What is the role of population genetics in the study of microevolution?

Microevolution can be studied by observing changes in the numbers and types of alleles, or genetics, in populations.


What is an artificial situation in which a scientist deliberately makes certain changes in the world about him so that he can observe the consequences?

An artificial situation created by a scientist to observe the consequences of specific changes is called an experiment. In an experiment, the scientist manipulates variables to test hypotheses and determine the impact of those changes under controlled conditions. This method allows for the identification of cause-and-effect relationships in the natural world.


Is physical and chemical changes a scientific method?

Chemical and physical changes are part of methods applied in science.
