1. Why is it important that an experiment include a control group? - correct answer C. Without a control group, there is no basis for knowing if a particular result is due to the variable being tested or to some other factor 2. Water is able to form hydrogen bonds because - correct answer E. The water molecule is polar 3. What determines the cohesiveness of water molecules? - correct answer C. Hydrogen Bonds 4. Which of the following is possible due to the surface tension of water...

They are symmetrically distributed on the lipid bilayer. b. They have a polar head group and one hydrocarbon tail. c. They are amphipathic. d. They have two hydrophilic tails. 3. Phosphatidylserine, a phosphoglyceride, is normally present on the cytosolic face of the cell membrane. However, when c...

ACS General Chemistry Unit 8 Acids-Bases Multiple Choice 82 Questions with Verified Answers In pure water, some of the molecules ionize according to the equation H2O ⇌ H+ + OH− The extent of the ionization increases with temperature. A student heats pure water and records the measured pH at 50°C as 6.6. Based on this information, which of the following mathematical relationships gives the pOH of pure water at 50°C ? - CORRECT ANSWER pOH = pH In pure water, some of the molecule...
