The study of living things is : BIOLOGY
In the hierarchy of life, species are made up of: POPULATIONS
Defining life precisely can be difficult, however, all living things share the following: cellular organization growth, development, reproduction energy utilization evolutionary adaptation
NOT…movement
“A concept in biology is: The whole is equal to more than the sum of its parts.”
This is termed: EMERGENT PROERTIES biological community All of the populations of different species living together in one place. population A group of organisms of the same species living the in same place. emergent properties Novel properties that result from the way in which components interact at each level in the living hierarchy. species All populations of one kind of organism whose members look similar and can successfully interbreed. ecosystem A biological community and the physical habitat within which it lives together. Deductive reasoning uses general principles to predict specific results, whereas inductive reasoning uses specific observations to formulate general principles; scientists use both types of reasoning.
There is no absolute truth in science; a theory can be rejected if data from a properly designed experiment does not support the theory, but it can never be proven
