<span>The sodium in sodium bicarbonate increases the sodium concentration in the blood stream. Through osmosis, larger amounts of water enters the blood stream, thereby increasing the person's blood pressure. For persons with already high blood pressure, this can prove to be dangerous.</span>
There must be a balance between the flow of energy into the atmosphere and the flow of energy out of the atmosphere and back to space.<span>After being warmed by incoming solar radiation throughout the day, the Earth emits infrared radiation, which is trapped near the Earth’s surface by carbon dioxide.This radiation is called thermal radiation.</span>
Answer:
The correct answer is B. DNA helicase first unwinds the double helix around the +1 site.
Explanation:
The helicase is an enzyme that specifically breaks the hydrogen bonds of the bases in the transcription process. As E. Coli is a prokaryote, then, the transcription only occurs in one point of the circular DNA. The promoter region indicates where the DNA polymerase has to start replicating and the Topoisomerase unwinds the parts of the DNA that are being excessively twisted because of the separation of the two strands.
