It is an example of directional selection.
The different kinds of natural selection can influence the distribution of phenotypes within a population. In stabilizing selection, an average phenotype is preferred.
In directional selection, a modification in the surrounding changes the spectrum of the observed phenotypes, and in diversifying selection the extreme values for a trait are preferred over the transitional values. This kind of selection usually pushes speciation.
The directional selection, in the field of population genetics, refers to a mode of natural selection in which an extreme phenotype is preferred over other phenotypes, making the allele frequency to change with time in the orientation of that phenotype.

since we are made from our dna
Answer:
B. 50 mM glucose; E. 300 mM glucose
Explanation:
In order for the cell to shrink the concentration of solutes in the blood should be above normal or higher than the intracellular concentration, so that water moves from the inside of the cell to the outside by the process known as osmosis.
The normal blood levels of NaCl = ~ 154 mM; therefore A, C and D will not cause any shrinkage.
The normal blood levels of glucose = ~ 3.9 to 7.1 mM; therefore water would move from the intracellular to the extracellular space since the solutes are 10x higher outside the cell, causing shrinkage of the cell.
Answer:
Hypochlorhydria is a condition in which the quantity of stomach acids is reduced. When severe forms of hypochlorhydria arise, then it leads to a condition termed as Achlorhydria. The stomach stops producing hydrochloric acid at all in such a condition.
The effects of Achlorhydria would be devastating on the body. It will
- weaken or entirely stop the digestive process.
- impair the gastrointestinal system.
- stop the proper digestion of proteins.
- cause gastrointestinal infections to occur which would entirely damage the digestive system.
- lead to iron deficiency
