- A hypothesis in biology is best described as a. a possible explanation of an observation. b. an observation that supports a theory. c. a general principle that explains some aspect of life. d. an unchanging statement that correctly predicts some aspect of lifearrow_forwardSome scientific reports are best described as correlations, in that they report on two events or conditions that tend to accompany one another. Correlations are often interpreted as evidence of a causal relationship between the two events or conditions. Other scientific reports involve experimental intervention and generally make a stronger case for a causal relationship. Pick one scientific conclusion that is put forth in this chapter that is based on both types of evidence. Which type of report do you find more convincing?arrow_forwardFormulate three (3) hypotheses.Hypothesis: cause and effect/premise and prediction - ”If..then..” statements Example: “If the glass is tapped, then the fish will swim away” There are four evaluation criteria that a hypothesis must meet. First, it must state an expected relationship between variables. Second, it must be testable and falsifiable; researchers must be able to test whether a hypothesis is true or false. Third, it should be consistent with the existing body of knowledge. Finally, it should be stated as simply and concisely as possible.arrow_forward
