<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
The bacteria must be outcompeted and substituted by bacteria that have gone this genetic factor. In addition, antibiotic resistance is a natural phenomenon. Once an antibiotic is used, bacteria that can fight that antibiotic have a greater chance of existence than those that are vulnerable. The vulnerable bacteria are exterminated or inhibited by an antibiotic, subsequent to a selective weight for the existence of resilient tensions of bacteria. Around opposition happens without human deed as bacteria can yield and use antibiotics in contradiction of other microorganisms, prominent to a low-level of the natural assortment of opposition to antibiotics. Though, the presently advanced points of antibiotic resilient bacteria are credited to the abuse and abuse of antibiotics.
The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.
That statement is true because The amount of energy at each trophic level decreases as it moves through an ecosystem at least is 10% of the energy at any traffic levels transferred to the next level the rest is lost largely through the metabolic process as heat.
