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?

An H+ ion is smaller than an H2O molecule, and a glycerol molecule, a three-carbon alcohol, is much larger. Both readily dissolve in H2O. Why do aquaporins fail to transport H+ whereas some can transport glycerol?
the concentraiton of partleces in a hyperosmotic solution is greater than in a hypoosmotic solution true or false?
Many, but not all, marine fishes are simultaneously both osmoregulators and ionoregulators. Say that a friend caught a fish off of the Cape Cod coast where the seawater has an osmotic pressure of 1,050 mosmol.L-1 and a Na+ concentration of 450 mmol.L-1. Which of the following plasma compositions might reasonably be consistent with your friend's fish being such an osmoregulating and ionoregulating species? A. plasma osmotic pressure = 350 mosmol.L-1; plasma Na+ concentration = 430 mmol.L-1 B. plasma osmotic pressure = 1,050 mosmol.L-1; plasma Na+ concentration = 450 mmol.L-1 C. plasma osmotic pressure = 1,035 mosmol.L-1; plasma Na+ concentration = 170 mmol.L-1 D. plasma osmotic pressure = 355 mosmol.L-1; plasma Na+ concentration = 161 mmol.L-1 E. None of the above answer choices correctly answers the question.
Increasing ventilation to remove accumulating CO2 in the blood will Increase the concentration of H+ Raise pH Shift the transport of CO2 to primarily the dissolved state Lower pH
When bacteria such as E. coli are starved to a sufficient extent, they become nonmotile. However, when such bacteria are placed in an acidic solution, they resume swimming. Explain
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?
