C) produce additional ER. D) undergo cell division. E) produce replacement lysosomes. 20) Rough endoplasmic reticulum A) contains ribosomes for protein synthesis. B) creates an enormous surface area for cell metabolism C) contains a compartment to transfer and modify products of metabolism D) all of the above 21) The function of mitochondria is
True or False: Liquid oxygen should have a larger surface tension than liquid bromine (assuming T and P are the same for both liquids). False: Surface tension of liquids increase as Intermolecular Force strength increases. Both O2 and Br2 are non-polar molecules, and have only dispersion forces. Those dispersion forces are stronger for Br2, however, since it has many more electrons (70 vs. 16) than does O2.
An SaO 2 (arterial oxygen saturation) value below 90% causes hypoxemia (which can also be caused by anemia). Hypoxemia due to low SaO is indicated by cyanosis. Oxygen saturation can be measured in different tissues: 1  Venous oxygen saturation (SvO 2) is measured to see how much oxygen the body consumes.2  Under clinical treatment, a SvO 2 below 60% indicates that the body is in lack of oxygen, and ischemic diseases occur.n medicine, oxygen saturation (SO 2), commonly referred to as sats, measures the percentage of hemoglobin binding sites in the bloodstream occupied by oxygen. At low partial pressures of oxygen, most hemoglobin is deoxygenated.
