Answer;

-Disruptive selection

Disruptive selection results in the creation of two distinct phenotypes.

Explanation;

-Disruptive selection is a type of natural selection that selects against the average individual in a population. The make up of this type of population would show phenotypes of both extremes but have very few individuals in the middle.

-The variance of the trait increases and the population is divided into two distinct groups. The disruptive selection will cause organisms with intermediate traits to reproduce less, and will allow those organisms with extreme traits to reproduce more.

Answer:

<u>Nutrition and health benefits</u> are the most likely motivation ,if a person decides to switch from drinking freshly squeezed orange juice to calcium-enriched orange juice after a yearly checkup,

Explanation:

As the Calcium enriched orange juice contains calcium almost equal to that of milk , hence it is an essential mineral which helps in building and maintaining strong bones and teeths.

What type of weathering can be considered the "rusting" of rock?
In-s [12.5K]
Hello,

Chemical weathering can be considered by the "rusting of rock". 

Weathering can be described of the breaking down of rocks and other materials on the Earth's surface. There are three types of weathering: mechanical, chemical, and biological. Mechanical weathering is the type of weathering in which rock is physically broken into smaller pieces. Chemical weathering is the type  of weathering in which chemical changes break down rock. Biological weathering is the type of weathering in which animal, plant, and microbes means weaken and or disintegrate rock.

In E. coli, the primary component of the mismatch repair system is the protein MutS. How does MutS recognize mismatched base pai
nignag [31]

Answer:

The best answer to the question, given the research found on this particular process in E. Coli specifically, would be: D) It identifies hemimethylated base pairs and methylates the unmodified base.

Explanation:

According to research on this pretty complicated topic, in E. Coli specifically, and other gram negative prokaryotes, it has been found that the presence, or absence of methylation will initiate MutS, which is a protein both in prokaryotes and eukaryotes responsible, in a full complex, of initiating and carrying out the full mechanism of DNA mismatch repair. As the daughter DNA strands are produced from parent strands, these first ones arise with several deletions and mismatches which need to be repaired and they are recognized due to the fact that daughter strands are hemimethylated. This circumstance activates MutS in E. Coli, who will then bind to the DNA strand that needs to be repaired and together with other members of the complex, like MutH and MutL, begin the process of repair.

In eukaryotes and other prokaryotes, the exact process by which DNA is repaired by MutS is still not totally known.
