The statement "Today people with very short sight can wear glasses with thinner lenses because the lenses do not need to be so powerful" is true.
Yes, this statement is true. People with very short sight (myopia) require corrective lenses that are concave in shape to help focus distant objects properly on the retina. The power of the lens is determined by the degree of myopia – the more nearsighted a person is, the stronger the prescription needed.
Advancements in lens manufacturing and design have allowed for the creation of high-index lenses. These lenses are able to bend light more efficiently than traditional lenses, meaning that they can achieve the required optical correction with less material. As a result, people with high prescriptions, whether for nearsightedness or other vision issues, can wear glasses with thinner and lighter lenses while maintaining the necessary corrective power. This has greatly improved comfort and aesthetics for individuals who require strong corrective lenses.

b. gel electrophoresis.
c. an electrical current.
d. whole animal cloning.
The answer is A .
PCR stands for Polymerase Chain Reaction. It is a method to analyze a short sequence of DNA or RNA and is used to reproduce (amplify) selected sections of the nucleic acid. Untold numbers of copies can be made of the DNA in just a few hours.
PCR amplifies the regions of DNA that it targets and can therefore be used to analyze extremely small amounts of sample. This is often critical for forensic analysis, when only a trace amount of DNA is available as evidence.
