WSU Biology 102 Exam 1 Carlyole Questions with well explained answers

Q What types of questions cannot be explored using scientific methods? - Answer-Is God real? What is the meaning of life? Anything that can't be experimented. Q What types of questions can science be used to explore? - Answer-Any question, prediction that an be tested in a scientific experiment. What is a hypothesis? - Answer-An idea about the outcome of an experiment. Logical explanation for observations of the natural world. Q Science is limited to hypotheses that can be falsified. What does this mean? - Answer-That Hypotheses must be made so that they can be proven either right or wrong, true or false. Hypothesis testing yields the facts of science. What is a scientific fact? - Answer-A repeatable observation of the natural world. Confirmed result of an experiment. What is a "theory" in science? - Answer-An explanation of a group of related hypothesis that has been repeatedly confirmed by diverse lines of evidence. Why does science never claim to have proven a hypothesis? - Answer-Because the hypothesis may be supported by evidence but it is not proven to be true. Q What language do they used when the data indicate their hypothesis is true? - Answer-Supported Define correlation - Answer-Two or more aspects of the natural world behave in a interrelated manner. If one shows a particular value, we can predict a value for the other aspect. Define causation - Answer-The action of causing something. Correlation does not establish causation. Experimental Treatment - Answer-Those who are exposed to the independent variableControl Treatment - Answer-Those who experience everything except the variable being tested Scientific experiment Independant variable? - Answer-Is manipulated by the investigator Scientific Experiment Dependent Variable? - Answer-Any variable that can potentially respond to the changes in the independent variable. Scientific experiment predictions? - Answer-What you would expect to see what were the dependent and independent variables in your termite experiments? - AnswerIndependent- The different pens Dependent- Termites & which way they moved Q What variables did you control in the pillbug and termite experiments? - Answer-The same type of bugs. The time they were in the dishes. The distance of the lines. Q What is peer-review? What does it accomplish? - Answer-Scientific journals that publish original research after it has passed the scrutiny of experts who have no direct involvement in the research under review. Non bias, outright fraud Q Drawing conclusions based on data can be challenging. What are some pitfalls that can lead to wrong conclusions? - Answer-They are bias conclusions, poorly constructed Q Do cell phones cause brain cancer? - Answer-No, because there isn't enough evidence Q What is pseudo science? - Answer-Characterized by scientific sounding statements but are not actually based on the scientific method Q What sorts of things can you look for in a study to help determine whether the methods are truly scientific? - Answer-Credentials, bias or an agenda, meet science standards, peer reviewQ What are some questions you can ask to help you determine the scientific credibility of a scientific claim? - Answer-Does the study meet science standards? How might causation vs correlation play into pseudoscientific claims? - Answer-Just because 2 things are both moving in the same direction does not mean that they are caused by one another
