What is a slow, continuous process while what is sudden and less frequent.
vladimir2022 [97]

Explanation:

A slow, continuous process is defined as gradualism that occurs at slow rate but at a steady pace.

For example, stripes of a tiger develop slowly and at a steady pace so that they can hide in tall grass represents gradualism.

Whereas punctuated equilibrium is a process in which there is sudden and frequent changes that results in the formation of new species.

aivan3 [116]

Answer:

The correct answer is "temporal lobe".

Explanation:

The temporal lobe is the part of the brain involved in primary auditory perception by receiving sensory information from the ears and secondary areas and translating in into meaningful units such as speech and words. It was proved since 1954 by Mishkin and Pribram that the removal of the temporal lobe part of the brain produces a severe visual discrimination deficit in monkeys. This is the case for Maria's experiment, when the monkey was not able to differentiate between the rectangle and the cylinder anymore. Therefore, it is very likely that the part of the monkey's brain that was removed was the temporal lobe.
