LIFESCI 23L Study Guide - Quiz Guide: Baroreceptor, Sympathetic Nervous System, Electrocardiography
Document Summary
Given t test value of 2. 581, p value of 0. 01 --> reject null hypothesis hypothetico-deductive approach, falsificationist procedure. Reject null hypothesis then hypothesis and model are supported. Takes into account difference between means and standard error of the two sample. Z buffer - gives optimum ph for enzymatic reaction. Na2co3 solution does not need to be kept on ice. Z buffer, onpg, e coli, lb+ glucose kept on ice. Conc of o nitro phenol was proportional to conc of b-gal. Cell produces more b-gal, lactose levels decrease, glucose levels increase. B-gal transcription is dependent on presence of lactose. Hand dynamometer - measure force w/ which hand can grip/pinch. Do not participate if knee pain, dizziness, arthritis, cold/flu. Observes pulse presonse to sudden standing from squatting. Baroreceptor should sense increase in pressure when person squats from standing. Measures movement of air in and out of lungs.
