3 0

The correct answer is "7 minutes".

The Rod-Cone-Break is considered to be a dark environment adaptation function in the eye, wherein for an estimated time of the first ten minutes in the dark, the cones needs less light to reach a threshold response than do the rods. Thereafter, the rods need less light. The point at which the rods become more sensitive is called the rod-cone break.

Answer:

fixed action pattern, key stimulus; key stimulus, fixed action pattern

Explanation:

An innate behavior which specific to a species and is highly stereotyped is termed as a fixed action pattern.
This behavior occurs due to a neuronal network that is hard-wired in the species and the response is said to be generated following a key stimulus.
A key stimulus is the one that generates a fixed action pattern and this is also called a releaser.
A key stimulus can be in the form of shape, sound, color, or a combination of these.
In this case, the red spot is a stimulus for the chicks which causes them to peck at their parent's bill, and hence, the red spot is a key stimulus, and pecking of the chicks is a fixed action pattern.
The parents regurgitate the food only when the chicks peck at their bills, so pecking is a key stimulus for the parents which causes them to regurgitate the food which is a fixed action pattern.
