Answer:
Option 5. Equal amounts of starch can be achieved only if starch moves from an area of high starch production to an area of lower starch production.
Explanation:
Deposition is the geological process in which sediments, soil and rocks are added to a landform or land mass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.
<em>Answer:</em>
<u>Polymerase Chain Reaction (PCR)</u>
Explanation:
Note that Polymerases Chain Reaction (PCR) is used to amplify food DNA to test for the presence of genetically modified DNA in food products because usually DNA fragments can be isolated from highly processed goods and are sufficiently intact to be amplified by PCR.
The process used by Genetic engineers is <u>called gel electrophoresis </u>where only a small number of regulatory sequences (promoter and terminator sequences) are used to control the expression of the inserted genes.
