The double helix of dna in the b form is stabilized by-
1. covalent bond between the 3' end of one strand and the 5' end of another strand.
2. hydrogen bonding between the phosphate groups of two side-by-side strands.

Because of the salt from the potato chip bag cause them to die and turn into slime.
Ok, DNA Polymerase is an enzyme that joins free nucleotides to both existing strands of DNA, which means it isn't D (which is helicase, by the way). They normally work in pairs of two for this function, so it isn't C; this is because if it created a fork, there would only be one needed. Now, concerning A & B, you'll have to be careful. Depending on how A is worded contextually, it could be correct, or it could not. I'm not sure I like the wording "chunks." Which is why I think it's B. Polymerase joins one strand of the "unzipped" DNA to free nucleotides that match it, and these aren't "chunks of DNA." Now, Polymerase is VERY accurate, only making a mistake once every millionth (or billionth?) nucleotide matchup. When it does make a mistake (most of the time), it'll go back and fix it. So I believe the best answer is B, it checks for errors.
Hope this helps!
The correct answer is [c] 7.35-7.45
The normal range of pH of arterial blood pH 7.35-7.45.
<h3>What do you mean by arterial blood?</h3>
Three different tests—pH, Pco2, and Po2—are typically taken in conjunction to assess the patient's acid-base state, ventilation, and arterial oxygenation. This group of measurements is referred to as arterial blood gases (ABGs). The most significant respiratory gases are oxygen (O2) and carbon dioxide (CO2), and the partial pressures of these gases in arterial blood indicate how well gas exchange is functioning generally.
Age and altitude have an impact on Pao2. Paco2 by height. As a result, Pao2 needs to be determined specifically for each patient, and both results need to be compared to the neighborhood's norms. Because hydrogen is not a gas in blood, it does not impose a partial pressure. However, every arterial blood gas determination includes pH, which assesses hydrogen ion activity. Blood pH should fall between 7.35 and 7.45.
The ABGs may include certain calculated or derived variables. The most helpful of these is the bicarbonate concentration, which may be determined from the pH and Pco2. Others are not necessary and could be confusing, such as base excess and base deficiency.

Answer: A. It is needed to support an aerobic metablism
Explanation:
All living organisms require oxygen for anaerobic metabolism. The oxygen taken in during cellular respiration is needed to breakdown sugar to generate energy in living organisms and this necessary for the advancement of life.
