Answer: Genetic test of C/T (-13910 polymorphism can be used as a first stage screening test for adult-type hypolactasia.
<span>Diffusion is the process in which particles in the cells move
from an area of high concentration to an area of low concentration. This
process usually occurs in lipid bilayers that are hydrophobic (water-fearing).
Osmosis is the process in which particles in the cells move from a low
concentration to a high concentration. This process usually occurs in glucose
that are hydrophilic (water-loving). <span>
<span>These processes occur until the cell reaches
equilibrium or balance. It is part of the many communications that cells make
to function properly in living organisms. </span></span></span>
DNA really is the information that everything else in the cell has to go by, which in my opinion, would be a great representation of laws as we have them in.
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 would say down wind side but I'm not 100% sure
