Describe the journey of a water molecule. Begin with it as water in the soil, and end with it as water vapor in the air outside a leaf. Describe a) the structures through which the water molecule moves, and b) the reason it moves during the different parts of the process.

Lipid bilayers form spontaneously in a process driven by the hydrophobic effect. Explain how the hydrophobic effect drives bilayer formation from individual lipids in an aqueous environment. Describe how the physical properties of the lipid bilayer are determined by the chemical properties of the membrane lipid components. Diagrams are encouraged for both parts of the question.

Match the term to the description. Cohesion Adhesion Solvent Evaporation [Choose ] [Choose ] The conversion of water to vapor. Without this property, water would quickly evaporate from the Earth's surface. Hydrogen bonds between water and other substances. Solutes are dissolved into this substance.

Explain the steps of the BIOSYNTHESIS OF PHOSPHOLIPIDS with a diagram.

What property of water helps retain heat in the water when air temperature drops?  cohesion    evaporation   density   adhesion

Biochemical oxygen demand (BOD) is a measure of the:   Question 4 options:   A)  number of bacteria present in a water sample   B)  amount of oxygen present in a water sample   C)  amount of organic matter present in a water sample   D)  amount of undissolved solid matter present in a water sample

All of the following are parts of the honeybee's processing of honey EXCEPT:     producing a small amount of gluconic acid.     concentrating the sugars to a supersaturated state.     conversion of some glucose and fructose into sucrose.     conversion of most of the fructose to the β-D-fructopyranose form.

Exchange of energy a) Give the two ways by which energy is exchanged between an organism and its surroundings. b) Give the symbol of each quantity involved in (a), their sign conventions, and the interpretation of the quantity with the indicated sign.

Part 1: In the image below (Figure 2) which way will water go?  Describe why in 1-2 sentences using the vocabulary of this lab. a) On a sheet of paper, sketch Figure 5 given above. Draw stars to represent the relative amounts of proteins on side A and side B of Figure 5 that result in water moving to the right, as shown by the arrow. Label Figure 5 with the following terms: “hypertonic”, “more solutes”, “less water”, “hypotonic”, “fewer solutes”, “more water”, semipermeable membrane.”  Part 2: Do you think any water molecules move in the opposite direction of the arrow?  Explain your answer in detail. a)  Describe in your own words why chloroplasts and mitochondria found within a photosynthetic, eukaryotic cell have two membranes.

Which of the following solutions is isotonic relative to a solution of 1.0 M glucose? 1.0 M glucose + 1.0 M fructose O 0.5 M Na+ + 0.5 M CI- O2.0 M glycerol
