Answer:
early all of the hydrogen consumed in the United States is used by industry for refining petroleum, treating metals, producing fertilizer, and processing foods. U.S. petroleum refineries use hydrogen to lower the sulfur content of fuels.
Explanation:
It is supported by evidence from a wide variety of scientific disciplines, including genetics, which shows that different species have similarities in their DNA. There is also evidence supporting the Theory of Evolution in paleontology and geology.
True because, more variation increases the species fitness, the ability to survive and reproduce. Allowing the organism to pass on their beneficial traits (advantageous traits), to their offspring.
Plasmid. A plasmid is a small circular DNA presents in bacterial cells. It is used as a cloning vector for DNA. The cloned DNA and the plasmid are treated with a restrriction enzyme. The enzyme will make cleaveges in the same portions of the two DNA. The plasmid is then allowed to be replicated inside the bacterial cell.
