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.
I believe it would be the red fox, though I could be wrong
Hey!!! I am working on this test right now and the best answer would be...
It determines how much of the surroundings an organism can see.
Weathering
Explanation:
When water freezes and thaws within cracks in rocks thereby eventually breaking it down into smaller pieces, it is physical weathering.
Erosion is the movement or washing away of loose rock materials or weathered materials. In erosion, movement of particles is involved.
- Weathering the physical disintegration and chemical decomposition of rocks to form sediments and soils.
- In this case, the rock is being physically broken into smaller pieces by freezing and thawing of ice.

Answer:
The genotype could be any of the the the two traits because they are 50/50 because there is no dominant trait. And the chance is 50/50.
