In a hot, dry desert a person can lose lots of water through sweating, but show no visible signs of sweating. One problem is that people may not realize how much water they are losing through sweating.
Why is it important to drink plenty of water under hot, dry desert conditions even when you do not feel like or realize you are sweating much? Beside dehydration, you should explain why the human body will overheat if unable to sweat under very hot and dry conditions.
A patient is hyperventilating. The "blowing off" of excessive carbon
dioxide causes a decrease in blood H+ concentration. How can the
carbonic acid buffering system function to correct this imbalance?
CO2 + H2O → H2CO3 → H* + HCO3
O H2CO3 dissociates to form more H+ and raise pH.
O HCO3- binds with H+ to form H2CO3 and raise pH.
O H2CO3 dissociates to form more H+ and lower pH.
O HCO3- binds with H+ to form H2CO3 and lower pH.
O none of the above
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?

- An American woman, Jennifer Strange, died in 2007 after competing in a water-drinking contest. She drank six liters of water in three hours in a radio station's contest titled "Hold Your Wee for a Wii (Nintendo Game Console)." After the event, she vomited, experienced a terrible headache, and died due to water intoxication. Studies show that drinking too much water can be detrimental to one's health as much as drinking too little. Explain how can drinking too much water be harmful.arrow_forwardWhich statement BEST distinguishes metabolic acidosis from respiratory acidosis ?

- When travelling high altitude, one of the problem is alkalosis of the blood. Remember the equation for acid balance: CO2 + H2O ⇌ H2CO3 ⇌ HCO3− + H+ If there is a low amount of CO2 outside, then greater CO2 than normal will diffuse out of the lungs. This will cause the blood to become more basic. To counteract the problem, a drug may be taken to both lower the blood pressure and help correct the pH. To do this, it blocks a symporter of HCO3- and Na+ in the proximal tubule of the kidney.
