90 mm Hg will be the partial pressure of dissolved oxygen in blood that leaves the lungs.
While there is a pressure gradient (a concentration gradient), oxygen will continue to move from the alveoli into the blood. The arterial blood gas is the primary method for determining the partial pressure of oxygen. This allows for the direct measurement of oxygen partial pressure, carbon dioxide partial pressure, acidity (pH), oxyhemoglobin saturation, and bicarbonate concentration in arterial blood.
A gas's partial pressure is the force it exerts. The sum of the partial pressures in a gas mixture equals the overall pressure. When forecasting gas flow, partial friction is extremely important. Remember that gases in two connected regions tend to equalize their pressure.

How is Cytochrome C, which is an important enzyme in cellular respiration, used to provide evidence for evolution. bones (homologous structures) are used for similar uses if the organisms are more closely related bones (homologous structures) are used for similar uses if the organisms are more closely related sections of DNA are more similar in organism more closely related. sections of DNA are more similar in organism more closely related. organisms that are more closely related are found with similar embryonic structures. organisms that are more closely related are found with similar embryonic structures. fossils in various layers are more closely related if they are in the same layer
Answer:
Sections of DNA are more similar in organism more closely related
Cytochrome c is used to provide evidence for evolution because most animals have this protein and is has undergone very little changes in these organisms such that more closely related species have the most similarity in amino acid sequence of cytochrome c
Explanation:
Cytochrome c is a protein found in mitochondria and is an important enzyme in cellular respiration. Cytochrome c is a highly conserved (have undergone very little changes) protein that in found in many different species of organismsmsuch as plants, animals, and many unicellular organisms. Cytochrome c is made up of about 104 amino acids linked together by peptide bonds. Being a small-sized molecule (molecular weight about 12,000 daltons) also makes it easier for evolutionary studies to be conducted on it.
Organisms that are most closely related have the most similarity in the amino acid sequence of the cytochrome c molecule. The amino acid sequences in cytochrome c molecule present in organisms is as a result of the information in their DNA.Thus, sections of DNA are more similar in more closely related organisms.
Which of the following is not an example of coevolution? A. Prey evolve faster running to escape, and predators evolve to smarter at catching prey. B. Predators evolve heavy jaws to crunch the bones of herbivores, and herbivores evolve thick fur for warmth. C. Plants evolve chemical defenses and herbivores evolve ways to neutralize the chemicals. D. Insects evolve green wings to blend into the environment, and predators evolve better eyesight to find the prey. Explain why.
The statement 'predators evolve heavy jaws to crunch the bones of herbivores, and herbivores evolve thick fur for warmth' is NOT an example of coevolution.
Coevolution is an evolutionary process where two or more species evolve in a parallel manner.Coevolution is caused by an evolutionary race between species.In general, coevolution is caused by selective pressures between one taxonomic group on another.In conclusion, the statement 'predators evolve heavy jaws to crunch the bones of herbivores, and herbivores evolve thick fur for warmth' is NOT an example of coevolution.
