More than one possible solution for each question,
* which of the following biotechnologies is used to rewrite the human genome?
crispr recombinant dna polymerase chain reaction

Sometimes called "molecular photocopying," polymerase chain reaction (PCR) is a fast and economical technique used to "amplify" - copy - small segments of DNA. Because considerable quantities of a DNA sample are needed for molecular and genetic analysis, studies of isolated segments of DNA are almost impossible without PCR amplification.

Often proclaimed as one of the most important scientific advances in molecular biology, CPR revolutionized the study of DNA to such an extent that its creator, Kary B. Mullis, was awarded the Nobel Prize in Chemistry in 1993.

Humans can affect weathering and erosion in several ways.  humans cause  increases in acid rain and pollution, which increase the amount of  weathering  agents in the air and water, and then on land.for an easy answer: 1) acid rain2) pollution

The answer is nucleic acid
