Which term means that objects or concepts are defined in a dichotomous manner (e.g., either the person has a fever or they do not)? - categorical The classification system published by the World Health Organization that includes specific criteria for the diagnosis of mental disorders is called what? - International Classification of Diseases What might be one reason to use n...

Biology 1107 Final Exam Study Guide (University Of Connecticut) 2024 along the length of the axon c. Action potential needs to be regenerated by the presence of more voltage gated sodium and potassium channels along the length of the axon d. So if axon is damaged, you would not have transmission of AP, it would never drive at the axon terminal and never release a neurotransmitter e. Myelin- a fatty cell type that wraps around the axon, allowing for jumping of action potential alon...

Components of a good Theory - Answer-falsifiable (can be proven wrong), testable (range of hypotheses) - high level it's based in empirical evidence Hypothesis - Answer-specific, testable prediction narrower than the theory it is based on Operational Definition - Answer-a definition that qualifies (describes) and quantifies (measures) a variable so the variable can be understood objectively Descriptive Research Design + Strengths/Weaknesses - Answer-observing behavior to describe behavior...
