The carbon dioxide carried in the blood is actually combined with water and carried in the red blood cells in the form of carbonic acid, which has a dissociation constant:

H₂CO₃ ↔ H⁺ + CO₃⁻

When the pH of the blood decereases, the concentration of H⁺ ions in the blood becomes high. This causes the equilibrium to shift backwards, as per Le Chatelier's principle. The H⁺ ions are converted back to carbonic acid and the pH is increased. The opposite occurs when the pH is too high.

Feliz [49]

Answer:

The correct answer is option b. "it has high face validity".

Explanation:

Face validity in a test is a very broad concept that simply refers to whether the test appears to be suitable to report what it claims to do. It is important to notice that high face validity in a test only means that the judgers of the test agree that the test is suitable, but it doesn't mean that the test is reliable for the patient and for the therapist. In this example, Kristoff should take other tests and examinations before he could be sure that he is not suffering from depression, particularly because he has many symptoms that indicate that he is depressed.
