Sensory transduction occurs when a sensory signal is turned into an electrical signal. Which of the following describes receptor potentials in this process? Select the correct answer. Answer 2 Points It occurs when there is a rapid change in the membrane potential from negative to positive. It is a response to a stimulus based on the strength of the stimulus. It is the increase in positive ions that can create an action potential. It is the magnitude of the difference in charges between the inside and outside of the cell.

Learning Objectives 13.1 The Rate of a Reaction Define the term "rate" generically and for chemical reactions. 13.3 The Relation Between Rate of a reaction to express the rate of a reaction in terms of a reactant Relation Between Reactant Concentration and Time Calculate the (1)/(2) life of a reaction. Consider the reaction NH4+(aq) + NO2-(aq) -> N2(g) + 2H2O(l). From the data in the table below determine the following: a. The rate law (meaning find Rate = k[NH4+]^x[NO2-]^y, and determine x and y.) Rate = x= y= b. The rate constant (k) with units. (Once you have the rate law, determine k.) c. Is the order of NH4+ and the order of NO2-related to the stoichiometric coefficients in the balanced chemical equation? Explain why or why not. The elimination of alcohol in the bloodstream by humans is a zero-order reaction. The legal limit for driving is 0.080(g)/100mL of blood (17.3mM). The average rate of elimination is about 0.015 (g)/mL-hour (3.25mM/hour). If a person has a blood alcohol level of twice the legal limit, how long will it be before the person can legally drive?
