Answer:
the diagram represents DNA
Answer:
In order to study or detect individual genes or specific DNA regions or mutations of interest, it is often necessary to obtain a large quantity of nucleic acid for study. Rather than isolate a single copy of the target DNA from a large number of cells, it is often more useful to generate multiple copies of a target from a single molecule of DNA or mRNA, via an in vitro amplification method.
Explanation:
Given :
560 gram of silicon dioxide.
To Find :
Number of moles of silicon dioxide in 560 gram.
Solution :
We know, molecular mass silicon dioxide is 60 gram/mol.
So, number of moles of silicon dioxide in 560 gram is :
Now, one mole of any compound contain 
.
So, number of molecules in 9.33 moles of silicon dioxide is :
Hence, this is the required solution.
Answer: Coughing, breathing deeply, frequent repositioning, and using an incentive spirometer.
Explanation:
