,CHECK ALL THE APPLY. Choose all options that best completes the statement or
answers the question.

must go through include __________.
14) ______
A) analyze data to support or reject hypothesis
B) create a natural phenomenon
C) observe a natural phenomena
D) develop a theory based on observations
E) develop hypotheses to explain phenomena
F) design experiments to determine if predictions are supported or not
