B. can be amplified in volume to result in many copies of the segment.
C. can be cut in specific locations to isolate DNA sequences.
D. can be sorted and mapped.
Answer:
B. can be amplified in volume to result in many copies of the segment.
Explanation:
The purpose of PCR is to amplify small amounts of DNA so that you can get a sample large enough to analyze (or use for some other purpose), especially in a crime scene. A. is referring to restriction enzymes, enzymes that cut at specific locations along DNA strands to create "sticky ends." C. is referring to restriction enzymes once again. D. is simply irrelevant.
Through the use of the polymerase chain reactions (PCR), small amounts of DNA can be amplified in volume to result in many copies of the segment. Thus, the correct option is B.
The polymerase chain reaction is a method widely which is used to rapidly make millions to billions of copies of a specific DNA sample, it also allows the scientists to take a very small sample of DNA and amplify it to a large enough amount to study in detailed study.
Polymerase chain reaction is fundamental to many procedures which are used in genetic testing and research work, including the analysis of ancient samples of DNA and identification of infectious agents as well. In this process, small amounts of DNA can be amplified in volume to result in many copies of the segment.
Therefore, the correct option is B.

Answer:1.) is LAW and 2.) is experiment
Explanation: i already did this
A theory is an accepted explanation of an observed phenomenon supported by empirical data, whereas the scientific method is an organized way of gathering information involving observation and theory to test scientific hypotheses.
1.) A theory is an accepted explanation of an observed phenomenon supported by empirical data. For example, the theory of evolution is an accepted explanation of the observed changes in species over time, based on a wealth of empirical evidence from biology, geology, and other fields. 2.) The scientific method is an organized way of gathering information involving observation and theory to test scientific hypotheses. This process includes making an observation, asking a question, doing research, constructing a hypothesis, testing the hypothesis through experimentation, analyzing data, and drawing a conclusion.
