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.
This means that warmer surface water requires less dissolved oxygen to reach 100% air saturation than does deeper, cooler water. For example, at sea level (1 atm or 760 mmHg) and 4Â°C (39Â°F), 100% air-saturated water would hold 10.92 mg/L of dissolved oxygen.n a stable body of water with no stratification, dissolved oxygen will remain at 100% air saturation. 100% air saturation means that the water is holding as many dissolved gas molecules as it can in equilibrium.
