The correct functions of your lungs contribute to the normal pH level of between 7.35 and 7.45. If your lungs do not exchange and remove carbon dioxide from your blood, the blood pH will change. A pH 6.4 reading of your blood indicates
A. a health problem due to the pH value being 10X higher OH- concentrations than normal in your body.
B. a health problem due to the pH value being 2X higher OH- concentrations than normal in your body.
C. a health problem due to the pH value being 2X higher H+ concentrations than normal in your body.
D. no health risk, as part of normal pH changes in your body that in this case bring it closer to neutral pH.
E. a health problem due to the pH value being 10X higher H+ concentrations than normal in your body.
E. a health problem due to the pH value being 10X higher H+ concentrations than normal in your body.

Assuming you have a typical plasma membrane at room temperature, which of the following conditions would cause an increase in membrane fluidity?
Group of answer choices 1. Increasing the length of the fatty acid chain. 2. Increasing the degree of lipid saturation 3. Increasing the number of un-saturated bonds in glycerol. 4. Increasing the number of double bonds in the fatty acid chains 5. Decreasing the length of the fatty acid chain. 6. Decreasing the size of the phospholipid head group. 7. Adding additional cholesterol Decreasing the number of un-saturated bonds in glycerol. 8. Removing some of the membrane cholesterol 9. Decreasing the degree of lipid saturation 10. Lowering the room temperature 11. Increasing the size of the phospholipid head group.
