characteristics.
it expands when it freezes
it dissolves solutes
Answer: Option (a) is the correct answer.
Explanation:
A water molecule contains two hydrogen atoms and one oxygen atom. The chemical formula of water is .
Here, hydrogen is electropositive whereas oxygen atom is electronegative in nature. Hence, oxygen atom pulls electrons from hydrogen atom and as a result partial positive charge develops on hydrogen and partial negative charge develops on oxygen atom.
Therefore, molecule of water becomes polar in nature.
Thus, water is considered a polar molecule because it has partial positive and negative charges at each end.
Answer:
The answer is It has partial positive and negative charges at each end.
Explanation:
When a neutral molecule has a positive area at one end and a negative area at the other, it is a polar molecule. Water is a polar molecule, because there is an irregular distribution of electron density in it. This means that water has a negative partial charge near the oxygen atom and a positive partial charge near hydrogen atoms.
All waves move through space.
All waves move through matter, from particle to particle.
All waves transfer energy parallel to the direction of wave motion.
A property that is common to all waves is that all waves carry energy.
Therefore, a common property to waves is that they all carry energy.

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.
