Evaluate the following question and answer choice, then select the *BEST* explanation below. An artificial “cell” consisting of an aqueous solution enclosed in a selectively permeable membrane is immersed in a beaker containing a different solution, the “environment,” as shown below. The membrane is permeable to water and to the simple sugars glucose and fructose but impermeable to the disaccharide sucrose. Identify the correct net movement of solutes into and/or out of the cell (labeled with solid arrows) and the net osmosis (labeled with dashed arrows).(d) Option (d) is incorrect because:

Converting nitrogenous waste into , seen in birds and reptiles, costs the most energy, but offers the least toxicity.

The physiology of animals and plants obey physical laws. As such, the water potential determines the passive flow of water. 1. FOR A FRESHWATER FISH: a. Describe the difference in water potential between the fish and its watery environment (in terms of relative osmolarity); include the passive flow of water between the fish and its environment. b. Describe at least one way the freshwater fish maintains osmotic homeostasis. 2. FOR A PLANT: a. Describe the difference in water potential (high vs. low) between the soil and the atmosphere on a sunny warm day after a rainstorm (so not too hot) when the plant is photosynthesizing. b. Use the words stomata, cohesion, adhesion, and tension to describe water transport in the xylem of a plant.
