Organisms become more variable in their responding as reinforcement becomes less frequent or predictable.
<h3>What are the factor influence the animal behavior ?</h3>
Behavior is an output of the action of an organism towards its changing external environment.
The major environmental factors affect animal behavior are behaviors are Territory Size, Diet, Family & Herd Size.
Beside this, Reinforcement and punishment can also affect the animal behavior.
Reinforcement is the event which strengthens the likelihood of a behavior where as punishment is the event that weakens the likelihood of a behavior.
Hence, organism are more variable response to reinforcement.

Answer:
Extension
Explanation:
Polymerase chain reaction is given by Kary Mullis and it contains three steps denaturation, annealing, and extension. In denaturation, the temperature is raised to 96° c so that the DNA can denature.
In annealing, the temperature gets reduced to 55°c so that the primer can bind to the complementary sequence. In extension, Taq polymerase is used to extend the new strand.
This enzyme is isolated from thermophilic bacteria and the temperature here is raised to 72°c so that the enzyme can extend the primer and make the complementary strand. So the right answer is extension.
