SORRY THAT I M UNABLE TO GIVE AMSWWR TO THE 3RD Question
Codominance is a form of dominance where alleles of a gene pair in heterozygous is completely expressed resulting to offsprings with a phenotype that is neither dominant or recessive. Incomplete dominance is a form of dominance in which one allele of a specific trait is not completely expressed over its paired allele resulting to a third phenotype in which the physical trait is a combination of the phenotypes of both alleles. Therefore, they are similar in that in both combine homozygous dominant and homozygous recessive. They are different in that in codominance shows both, heterozygous while incomplete dominance shows mixture or blend, new trait and heterozygous.
<span>Hay fever is a manifestation of allergic reaction
from pollen, which is prevalent during haying season. Hay fever is commonly
known as allergic rhinitis caused by an oversensitive immune system,
particularly the lymphocytes, leading to a misdirected immune response. The body
undergo a sensitization when one develops IgE antibodies and develop a strong
TH2 response against pollen. Then, this newly develop IgE antibodies sticks to
basophils and mast cells with no signs and symptoms yet. However, when one is
expose again to pollens, mast cells will be activated and release mediators who
are responsible for immediate vascular and smooth muscle reaction. After this, local
clinical manifestation of hay fever will be observed. </span>
Answer:
The correct answer will be option-hypertonic and the cell will shrink in this solution
Explanation:
In the given question, the person drank the water with high salt concentration. The solution with high salt concentration and low water concentration is known as the Hypertonic solution.
When the person drank the water, the red blood cells with a low amount of salt and high amount of water as compared to the salt water lost their water through "osmosis" as the movement is driven by the concentration gradient from high water concentration to low concentration. As a result of this outward movement of water, the cell shrunk and the person died.
Thus, hyper tonic is the correct answer.
