How does active transport help the Atlantic cod maintain homeostasis with regard to the balance of sodium and chlorine ions
kotegsom [21]

Atlantic Cod is a marine fish. The fish has less salt in its internal body while the salt concentration in the sea water in which the Cod lives is high. Thus through the process of osmosis ( a process in which an element moves across a permeable membrane from regions of high concentration to the regions of low concentration) the salt moves from the ocean into the fish body. In such scenario the metabolism of the fish body gets disturbed, and there is an urgent need to remove the excess salt with the help of Kidney (through extremely concentrated urine) by going against the concentration gradient in order to maintain the homeostasis.

Which molecules are added to an electrophoresis buffer for the purpose of denaturing dna?
Oksi-84 [34.3K]

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.
