Explanation:
Question number one:
The correct answer is B
In the case of the starlings and their offspring, we can observe the workings of a stabilizing selection. (Presented in image number one).
Stabilizing selection tends to eliminate the extremes and favor the medium value of a trait, in this case, the number of offspring.
Question number two:
The correct answer is C.
In this example, we can observe the disruptive selection.
This type of selection favors the extremes and eliminates the medium values. In our examples with seed crackers, this means that the birds with large or small beaks are favored and the ones with medium sized beaks are eliminated. ( see image number two)
Question number three:
The correct answer is 2cm.
As we have seen on the graph number one, stabilizing selection tends to favor the medium values of a trait.
In the case of the acorns, the stabilizing selection will favor the 2cm circumference acorn, and after 10 generations we could expect the most common cicrumference to stay 2cm, because it was favored by the natural selection.
The intensity of a stimulus, such as the intensity of noise that a person experiences, can be communicated through the number of neurons that fire action.
A stimulus is a change detected by the neurons in a body for which a response is produced. The sensory nerves sense a stimulus and send signals to the brain. The brain interprets this message and sends a response action signal through the motor neurons.
The intensity of a stimulus is detected by the impulse of action potential carried by the sensory neurons. The number of sensory neurons will increase if an intense stimulus, which will lead to the generation of an increased action potential. The brain will determine the intensity of the increased action potential and send a response action from the motor neurons to act accordingly.

The answer is b. They both lay amniotic eggs.
Both birds and reptiles belong to a clade of vertebrates, Amniotes, which lay amniotic eggs. Mammals also belong to Amniotes. Amniotic eggs can remain within the mother after fertilization or can be laid on land. On the other side, <u>an</u>amniotic eggs are usually laid in the water.
