Research on brain development suggests that risky behavior in teens may be the result of incomplete development and changes that occur in the prefrontal cortex of the brain.
The prefrontal cortex is located in the frontal lobe, behind the frontal cortex. The function of this region is for executive function, an ability to differentiate good things from bad things and consequence of an activity. Incomplete development will impair those abilities, makes the teens do risky behavior.

Crude oil is piped from an underground reserve to the surface.
Crude oil is transported to a refinery by pipeline or tanker
crude oil is refined to make gasoline and other products.
Gasoline is transported by tanker truck to a gas station
Gasoline is pumped into a car‘s gas tank.

The answer is <em><u>not</u></em> Organisms would be classified based only on physical characteristics!!
I strongly feel that it would be....
<em>--the existing classification system may change to accommodate the new information.--</em>
<em>Reason:</em> Some things would not just be classified by appearance. Rather, this would add more possibilities to classification. We know that plants and dogs look nothing alike yet they are still related through the Domain (Eukarya).
I also took this test and relied on the other answer, sadly, it was incorrect.
I hope i could help! Let me know if this is incorrect. ~ Ninja Cat :D
Formamide molecules are added to an electrophoresis buffer for the purpose of denaturing DNA.
<h3>What is the purpose of the buffer during electrophoresis?</h3>
A laboratory procedure called electrophoresis is used to divide DNA, RNA, or protein molecules according to their size and electrical charge. The molecules are moved by an electric current through a gel or other matrix. In the case of Denaturing Gradient Gel Electrophoresis (DGGE), the gradient can be an electrical field or a denaturant such as a solution of urea and formamide.
Size, charge, and other characteristics are used in electrophoresis to separate macromolecules like protein and nucleic acids. Scientists utilize buffer to transport the charge through the gel for electrophoresis that separates by charge. Additionally, the buffer keeps the gel's pH steady, reducing alterations that would take place in the protein or nucleic acid if the pH were to become unstable.
