Answer:
make a decision about the stimulus.
Explanation:
Donders wanted to find out the level of cognition that was required in order to react to a stimulus. Cognition is the act of receiving a stimulus and understanding it completely.
The reaction time of various stimuli were noted and analyzed. The stimuli differed by their level of complexity. A longer time would indicate that the brain was taking longer to complete the cognitive processes. This was one of the first experiments in the field of cognitive psychology.
Answer:
The sample contains protein.
Explanation:
Biuret test is a test used to determine or assay for proteins in a solution. When the biuret reagent is added to a solution and it turns blue after 2 minutes, it means that the solution contains protein.
Benedict’s test is used to determine the presence of sugar (reducing sugar) in a solution. When it turns brick red, it means there is the presence of reducing sugar in large quantity.
From the question, since the solution turned blue on addition of Biuret reagent and was also blue on addition of Benedict’s reagent (the reagent is usually blue), it means that the solution contained just proteins excluding reducing sugars.
Division of labor and specialization, which were promoted to a large extent by Henry Ford and Frederick W. Taylor with the goal of increasing productivity and efficiency, contribute to economic growth because the worker, by being specialized, executes one, and the same, task or job over and over again, and, as a result, the final product or service is cheaper, of higher quality, and is produced in a shorter amount of time.
It was the Scottish economist and philosopher Adam Smith (1723-1790) the one that established that division of labor and specialization were the basis of productivity growth and wealth.
