There are seven base units in the system, from which other units are derived. Universal for comparing data. physical science - ANS the sciences concerned with the study of inanimate natural objects, including physics, chemistry, astronomy, and related subjects. life science - ANS the study of living things controlled experiment - ANS An experiment in which only one variable is manipulated at a time. Or a condition that is being held constant independent variable - ANS what is being changed dependent variable - ANS what is being measured control - ANS In an experiment, the standard that is used for comparison Observational experiment or study - ANS studies attempt to understand cause-and-effect relationships.
