Maria is known to favor some of her employees over others. for those she dislikes, she sets impossible performance goals so that they cannot possibly succeed, and their motivation suffers. this is an example ofa. positive reinforcement. b. negative reinforcement. c. punishment. d. extinction. e. motivation.

EXTINCTION

Explanation: Extinction is a method in reinforcement theory. As per reinforcement theory one can change someone behavior by using three methods reinforcement, punishment and extinction. In simple language extinction is stopping someone from performing a learned behaviour. Extinction is, followed by a discriminative stimulus, a response is no longer reinforced.

In this case study maria is doing extinction as she is discriminating employees on the basis of her preference for stopping them to succeed .

ans.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'

answer; i believe its (d) intrinsic;
