8. Which of the following statements are accurate?
A. In an average, healthy human, the partial pressure of carbon dioxide is usually higher in the body tissues than the systemic arteries.
B. In an average, healthy human, the partial pressure of oxygen is usually higher in the pulmonary arteries than in the body tissues.
C. Generally speaking, gases will diffuse up their pressure gradient
D. In an average, healthy human, the partial pressure of carbon monoxide is usually higher in systemic veins than the alveoli
E. In an average, healthy human, the partial pressure of oxygen is usually higher in the systemic veins than the alveoli

an active site is a region that is present on an enzyme where the reactants or the substrate molecules we can say bind and experience a chemical reaction. the substrate is basically a reactant whose concentration is changing and that is converting into a product after binding at the active site of an enzyme

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.'
