Answer:
Disruptive selection.
Explanation:
Natural selection is the result of the phenotype-environment interaction which determines gene destiny in space and time, selecting beneficial alleles and increasing their frequency in the population. There are different types of natural selection: sexual selection, stabilizing selection, directional selection, frequency-dependent selection, and disruptive selection.
The disruptive selection causes an increase in the two types of extreme phenotypes over the intermediate forms. Limits between one extreme and the other are frequently very sharped. Individuals belonging to one phenotype can not live in the same area as individuals belonging to the other phenotype, due to the traits differences between them, competition, predation, etcetera.
In the proposed case, each population of mice is adapted to its environment: one of them is dark-furred as the color of the dark patches it lives on, and the other population is light-furred as it lives in light patches. These adaptations are probably related to survival strategies and help them to avoid predators as they camouflage with the substrate.
Both extreme phenotypes have been favored over intermediate forms, resulting in the development of two groups with very marked differences. Grey-furred mice population belongs to the intermediate phenotype which can be seen everywhere and be preyed upon more heavily. Disruptive selection does not favor this phenotype.
Disruptive selection can lead to speciation, driving to evolution. This is why it is also called "diversifying selection".
The correct answer is B. AUG
Explanation:
In biology, translation refers to a process that occurs in cells as proteins are synthesized, translation occurs after transcription and implies the de-codification of messenger RNA that contains genetic information to a polypeptide (chain of amino acids). This process occurs as codons in mRNA attach to anticodons, the first codon in this process is an AUG codon that is attached to Methionine amino acid. This occurs in most cells including prokaryotes and eukaryotes although and just in very rare cases the translation begins with a different codon. Thus, the codon that is most often recognized as the start codon for translation is AUG.
The Sun dumps a lot of thermal energy by sunlight into the atmosphere, and especially into the oceans. Basically, currents arise as warm equatorial waters move to the NORTH carrying heat, and as part of this flow, the cold polar waters go south and there get heated. Then, the SUN is like an engine which drives ocean currents.

When working out, it's important to not only craft and individualized workout that works best for your body, but to make each workout focus on a specific area of the body, so that each area gets a particular amount of focus.
Answer:
The fiber in carrots can help keep blood sugar levels under control. And they're loaded with vitamin A and beta-carotene, which there's evidence to suggest can lower your diabetes risk. They can strengthen your bones. Carrots have calcium and vitamin K, both of which are important for bone health
