TASK DEFINITION: In this task, you are given a question and answer options for that question. Using this information, you have to classify each text into different topics: medicine, nursery, psychology, chemistry, pharmacology, biology.
PROBLEM: Question: The state of adaptation characterized by the diminution of the response to the same amount of drug or the need for a higher dose to cause the same degree of pharmacological effect, defines: 
 Options:  <0> The adaptation to a drug. <1> The route of administration. <2> Intoxication <3> Tolerance to a drug <4> Addictive behavior

SOLUTION: psychology

PROBLEM: Question: One of the following types of transport through membranes does NOT exist: 
 Options:  <0> Ion transport facilitated by ionophore (against electrochemical gradient). <1> Facilitated diffusion (in favor of electrochemical gradient) <2> Primary active transport (against electrochemical gradient). <3> Ionic channel (in favor of electrochemical gradient). <4> Simple diffusion (in favor of concentration gradient).

SOLUTION: pharmacology

PROBLEM: Question: The voltammetric methods of anodic redissolution: 
 Options:  <0> They are based on the preconcentration of analytes on the surface of an electrode and are characterized by their low sensitivity, since the surface of the electrode is very small. <1> They apply exclusively to the determination of traces of metals by oxidation on a mercury electrode. <2> They require the application of a stage of accumulation and another of redisolution in which intensity-time curves are recorded. <3> They are used for the determination of metals that, once deposited, are oxidized electrochemically. <4> They are based on the variation of the potential that the working electrode experiences as the deposited substance is redissolved.

SOLUTION:
chemistry
