1) a. When KCl is injected into the bloodstream of the patient‚ the K+ gradient across the membrane is reduced. This results in depolarization where cells generate an action potential. Voltage-gated Na+ channels open in response to depolarization and close by inactivation for a refractory period and remain closed until repolarization. In this new setting‚ less K+ leaks out of the intracellular space and the cell is unable to return to its resting membrane potential (ie. The cell stays slightly depolarized)

Juanita Sarmiento Daphnia Ecotoxicology Lab Report Introduction Ecosystems have a way of maintaining themselves under ordinary conditions but when a new factor is added that will most likely threaten the environment action needs to be put forth. Our environment is affected by many pollutants on a daily bases forming a threat to natural stability. For example some of the most polluted parts of the environment are bodies of water like that explained in our lab. Once pollution occurs

Laboratory No 4 Electrical Systems 100 AC CIRCUITS INTRODUCTION The purpose of this laboratory test was to make comparisons between theoretical and practical results and to develop a greater understanding of factors affecting the operation of complex AC networks. SUMMARY OF RESULTS The error in the results ranges from 0.02% to 22.63% and the phase angle errors ranged from 0.02° to 17.27°. This suggests that part of our results were very accurate (series parallel RC network) and the rest

Engineering requires theory to develop and test constraints while also requiring practical application of theory in order to determine tolerance and practical results for industry purposes.
