It is a cool winter evening, and you are feeling a little chilled. To warm yourself up, you sip some hot tea. As you swallow, you can feel the tea warm your mouth and throat. The drink is warming you up by the process of

Cormorants are sea-dwelling birds that consume high levels of salt from the seawater they drink. To get rid of this excess salt, cormorants "sneeze" out the salt that has collected in a localized area near their sinuses. This process is an example of

After reading the paragraph below, answer the questions that follow. Most fishes can live either in freshwater or in saltwater habitats, but not in both. If you move a marine fish from the ocean to a lake, it will quickly die, and vice versa. However, a small number of fish species are capable of moving between the two environments. Salmon are osmoregulators that hatch in rivers, spend most of their lives in the ocean, and return to the river where they were born in order to breed. -When a salmon leaves the river and moves out to sea, you would expect ________ to leave its body by osmosis and that excess ________ would need to be pumped out.

When a dolphin consumes a large volume of water and electrolytes, it must be able to get rid of large volumes of water via urine and feces. This is an example of the process of

What is the advantage of excreting nitrogenous waste in the form of ammonia?

Thermoregulation, an important part of homeostasis, is defined as

During filtration in the glomerulus, which of the following enters Bowman's capsule from the bloodstream?

Natural selection is nature's mechanism for selecting characteristics that best adapt the animal to its environment. Mammals have evolved a sophisticated mechanism for eliminating nitrogenous wastes that involves

The first step in the formation of urine is the

Which of the following statements regarding the urinary system is true?

There was a third group (group 3)in this study that experienced the same test conditions as groups 1 and 2 except that the water to which group 3 was exposed always had a chloride concentration (mg/L)that salamander clutches would normally experience (that is, with no road salts in the water). How would you describe this group?

When humans are cold, they often shiver. Shivering increases their ________, thereby warming their bodies.
