When animals oxidize stored fat, they produce metabolic water.Even though the production of metabolic water from stored fatfollows principles of chemical stoichiometry, the net gain of waterthat animals realize from the oxidation of stored fat depends onthe humidity of the atmosphere. Explain why. Does the net gainincrease or decrease as the atmosphere becomes more humid?

When blue crabs living in full-strength seawater swell duringmolting, they take on the H2O that bloats their bodies from theseawater in which they live. They obtain some of the H2O bydrinking. In addition, data show that the activity of Na+–K+-ATPase in their gills increases as they start to swell duringmolting. This rise in ATPase activity suggests that the gillsincrease active transport of ions from the surrounding seawaterinto the blood of the crabs. How could this process help accountfor uptake of H2O?
The adaptations of desert animals to their environmentinclude water conservation mechanisms. A number of theseorganisms conserve water so successfully that they neveractually drink it. They depend instead on water generatedduring metabolism. Determine how much water can beobtained by the oxidation of 1 mole of palmitic acid.
Oxygen comes from theenvironment and carbondioxide in the end returns tothe environment. How dosmall animals solve theproblem of taking away andbringing these moleculesfrom/to their cells? Why isn'tthat solution possible forlarger animals?
Using the set of data that follows, calculate how many of themolecules of O2 that were used in aerobic catabolism by JuliusCaesar are in each liter of atmospheric air today. All valuesgiven are expressed at Standard Conditions of Temperature andPressure (see Appendix C) and therefore can be legitimatelycompared. Average rate of O2 consumption of a human maleduring ordinary daily activities: 25 L/h. Number of years afterhis birth when Caesar was mortally stabbed near the RomanForum: 56 years. Number of liters of O2 per mole: 22.4 L/mol.Number of moles of O2 in Earth’s atmosphere: 3.7 × 1019 mol.Number of molecules per mole: 6 × 1023 molecules/mol. Amountof O2 per liter of air at sea level (20°C): 195 mL/L. Be prepared tobe surprised! Of course, criticize the calculations if you feel theydeserve criticism.

On a hot summer day, you decide to dive into a swimming pool.Before you begin your dive, you notice the surface of the water issmooth and continuous. After the dive, you discover that somewater droplets are clinging to your skin and that your skin temperature feels cooler. Explain these observations based on theproperties of water.
If the trend continues as shown in the data what would the dissolved oxygen level most likely be if the temperature of the water was 35C?
A fish swims from a body of cool water into a body of warm water. As its body temperature rises, its rate of O2 consumption increases. The warm water, however is likely to have a lower concentration of dissolved O2 than the cool water because the solubility of O2 in water decreases as temperature increases. These two factors taken together, an increase in the fish's rate of O2 consumption and a decrease in the dissolved O2 concentration of its environmental water, can make it difficult for the fish to obtain enough O2 to meet its needs. The two factors can act as a two-pronged trap. Actually, however, the fish may face a three-pronged trap. How is the increase in temperature likely to affect the O2 affinity of the fish's hemoglobin, and how could the effect on hemoglobin add even further to the challenge the fish faces? Does global warming pose concerns of this sort?
