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.

The earth moving and shifting the ground below.
Answer:
B. White light increases photosynthesis in plants.
Explanation:
Photosynthesis in simple term is defined as the process an organism uses the energy got from light in order to utilise CO2 and H2O for the production of glucose/organic matter and O2 as a gas. Examples of these organisms include,
plants, bacteria etc
6CO2 + 6H2O --> C6H12O6 + 6O2
Light can be absorbed by pigments in the oragnism cell like chlorophyll. Different pigments absorb different wavelengths of light. Leaves of a plant are green because the chlorophyll within them absorb all the other wavelengths of light in the spectrum and reflects green light. Absorption spectrum shows that red and violet light are the most absorbed whereas green light is most reflected.
A white light has maximum photosynthesis because white light is polychromatic i.e of varying colours so it could absorb blue, red, violet etc.
So therefore, White light increases photosynthesis in plants.
Five levels of ecological study include
(i) Population
(ii) Organismal
(iii) Ecosystem
(iv) community
(v) Global
