4 Water 400 Given the following: 20 H 2 CO 3 20 HCO 3 - + 20H + How would the equation shift to accommodate the addition of 5NaOH? Water 400 Answer: 20 H 2 CO 3 + 5 NaOH 5 NaHCO 3 + 15 HCO 3 - + 5 H 2 O +15 H + Water 500 Why is a water strider able to stride across water? Water 500 Answer: Water has high surface tension because of the cohesion between water molecules (H-bonds hold the molecules together). The water strider distributes its weight to reduce the force it places on the surface. Lipids & Carbs 100 What type of carbohydrates are in a glycoprotein? Lipids & Carbs 100 Answer: Oligosaccharides

5 Lipids & Carbs 200 Draw a diagram of a phospholipid and label its components polar or non-polar. Lipids & Carbs 200 Answer: Polar head Non-polar tails Lipids & Carbs 300 How is the structure of a triglyceride and a phospholipid similar? How is different? Lipids & Carbs 300 Answer: Both have a glycerol and fatty acids. A triglyceride has 3 fatty acids. A phospholipid has 2 fatty acids and a phosphate-containing group.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
