GCU BIO 181L Midterm QUESTIONS WITH COMPLETE SOLUTIONS

hypothesis correct answer: a well framed statement that can be tested, falsifiable, and replicated independent variable correct answer: The experimental factor that is manipulated; the variable whose effect is being studied. dependent variable correct answer: the variable that changes in response to manipulations of the independent variable. control group correct answer: the group that is not exposed to the treatment experimental group correct answer: the group that is exposed to the treatment, that is, to one version of the independent variable. why formulate a hypothesis correct answer: five steps of scientific method correct answer: 1) observation 2) question 3) hypothesis 4) experiment and observe 5)conclude hypothesis vs theory correct answer: A hypothesis is a reasoned prediction of a possible causal correlation among multiple phenomena. a theory is a tested, well-substantiated, unifying explanation for a set of verified, proven factors. hypothesis based science correct answer: Explains the nature by proposing hypothesis and predicts the specific results by applying general principles and using Controlled variables in an experiment. observation-based science correct answer: still experimenting but conclusions are derived from the observations made in the lab, there isn't any "numerical" data cell in hYPOtonic solution correct answer: cells inflate like a balloon until they pop because so much water is coming into the cell cell in hYPERtonic solution correct answer: cells become shriveled up and lose function because they're losing so much water total magnification formula correct answer: total = eye piece (usually 10x) * objective lenses (4x,10x,40x) formula for estimate size of an organism correct answer: FOV di
