Answer:

including constants

Step-by-step explanation:

A scientific constant is an experimental variable that remains unchanged throughout the experiment. The reason for this is to properly identify the relationship between the dependent and independent variables in the experiment. Knowing that external factors such as temperature and the location of a place can affect an experiment if changed, they are kept constant so that whatever final results are achieved at the end are true and accurate.
