EMI 501: Which of the following hypotheses is consistent with the information presented in the passage? A. If crude oil mixture is super-heated to 200 degrees C then the residue is the only substance that will not condense

B. If crude oil mixture is super-heated to 200 degrees C, then lubricating oil stocks and residue are the only substances that will not condense

C. If crude oil mixture is super heated to 200 degrees C, then the gas oil, lubricating oil stocks, and residue are the only substances that will not condense

D. If the crude oil mixture is super heated to 200 degrees C, then the petroleum, gas, gasoline, kerosene, and gas oil are the only substances that will not condense

help me please help me please​

The answer is B

Explanation:

On the chart, it shows what temperature the oil is superheated and what is created at what temperature. So based of that, by superheating crude oil to 200 degrees C the only liquids left are lubricating oil stocks and residue which is basically answer B.

I hope this helps you

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
