DNA isolation is a process of purification of DNA from sample using a combination of physical and chemical method while on the other hand, Polymerase chain reaction (PCR<span>) is a technique used in molecular biology to amplify a single copy or a few copies of a piece of DNA across several orders of magnitude, generating thousands to millions of copies of a particular DNA sequence.</span>
Answer:
The chemical reactants on the left produce<u><em> Adenosine triphosphate (ATP)</em></u> on the right.
Explanation:
Adenosine triphosphate (ATP) can be described as the energy molecule which is used by almost every cell of an organism's body to carry out normal functions of a cell.
Adenosine triphosphate (ATP) is an unstable molecule hence it usually occurs as ADP ( Adenine diphosphate) or AMP (adenine monophosphate). When a phosphate atom attaches to ADP, ATP is produced. The breakdown of ATP releases adenine diphosphate, phosphate along with the release of energy.
Answer: The overgrowth in deer population led to a food shortage.
Explanation:
Since the eradication of the wolves, the deer had no predator to keep their total population in check. Due to the vast amount of deer the food in the area was being eaten at a faster rate. Most of the deer died do to their environment not being capable of feeding that many deer.

Answer:
A) Fatty acids
Explanation:
Sterols are the organic compounds composed of the four rings fused together, an attached hydrocarbon chain and the characteristic functional group called -OH group attached to the ring.
The steroids are the compounds which contain the fused rings (a feature of sterol) and the attached -OH group. The presence of the hydrophobic chain provide makes them insoluble in water which is considered a characteristic feature of the lipids. Therefore the steroids are considered the lipid molecule or fatty acid-containing molecules.
The cholesterol is the most common type of sterol present in the organism, especially in the animal and plants.
Thus, Option-A is the correct answer.
Answer:
Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.
Explanation:
Cells need a source of energy, they get this energy by breaking down food molecules to release, the stored chemical energy. This process is called 'cellular respiration'. The process is happens in all the cells in our body. Oxygen is used to oxidize food, main oxidized food is sugar(glucose).
