Crude oil is <u>refined to separate the chemicals used for gasoline, lubricants, plastics, and other products.</u>
<u />
- In a distillation tower, the crude oil is separated by boiling point after being heated by a furnace.
- The material is then transformed into finished goods like fuels like gasoline and diesel, as well as specialty items like asphalt and solvents, by using heat, pressure, or a catalyst.
- Ethane, liquid petroleum gas (LPG), and naphtha are the three main petrochemical feedstocks generated from crude oil.
- These are mostly employed in the creation of synthetic fibers, plastic polymers, and other petrochemical intermediates.
- With increased global income, demand for these products will only continue to rise.

Answer:
True
Explanation:
This would be like a birth to death ratio. If you have more deaths than births your population would decrease. See a similarity?
Answer:
Explanation:
DNA polymerases are the enzymes that build DNA in cells. DNA polymerase also proofread their work to check for any error the process of which is called proof reading.
If the polymerase detects that an Incorrectly paired nucleotide has been added, it will remove (splicing) and replace the nucleotide with the correct one before it continues with DNA synthesis.
Mismatch repairing also corrects other errors that omit proofreading. They fix mismatched base pairs, replace some insertion and deleted base pair that can result into mutations.
When an error is corrected the rate of mutation is reduced this is because mutation results from error during the DNA formation process either through Insertion of a wrong nitrogenous base, or deletion leading to formation of an entirely new amino acid sequence that result into abnormal phenotype.
