Answer:
Essential fatty acids, or EFAs, are fatty acids that humans and other animals must ingest because the body requires them for good health but cannot synthesize them
<h2>B) option is correct </h2>
Explanation:
Natural selection is a selection pressure which operates in a population and allow the best fitted genotype to survive in changing environmental conditions and eliminate the other genotype which are not fit
In artificial selection, breeders select superior breed for the breeding purpose so that this type of selection favors the superior genotype and eliminates inferior genotype, thus leading to genetic drift
Stabilizing selection is a type of natural selection in which intermediate genotype is favored but extreme genotypes (inferior and superior) are eliminated
In the given example of pigmentation in pigeons, breeding is selectively done with intermediate pigmentation hence intermediate genotypes will be favored
Traits that are sex-linked are carried on either the X or Y chromosome. If they are carried by a female, they are X-linked traits, and if they are carried by a male, they are Y-linked traits.
After putting distilled water in Elodea, the cells of Elodea represent a hypotonic solution, yet the cells do not burst because of the cell wall.
<h3>What is a hypotonic solution? </h3>
A solution that contains fewer dissolved particles than exists found in normal cells and blood. In this solution the cells obtain swell.
A hypotonic solution contains a lower concentration of solutes than another solution. In biology, a solution outside of a cell exists named hypotonic if it contains a lower concentration of solutes relative to the cytosol. Due to osmotic pressure, water diffuses into the cell, and the cell often seems turgid, or excessive.
The Chloroplast exists spread throughout the cell both before the salt solution, and after the distilled water exists put on the slide. Distilled water symbolizes a hypotonic solution, yet the cells do not demolished because of the cell wall.
