Suppose you take a drug that blocks your ability to secrete certain compounds in urine. What structures are most likely to be affected? - ANSWER Convoluted tubules You consume a large number of antacids due tooo acid upset; you are mimicking the actions of the ____ that also produces bicarbonates. - ANSWER Stomach Mammals belong to the subphylum - ANSWER Craniata Which of the following is not one of the main features which characterize ALL Chordates from other taxa? - ANSWER Ventral Ner...

Convection - *Transfer of heat by movement of liquids and gases (Molecules of air or water next to warm surface gain energy and move away from surface)*When environment is cold, organism warms it's boundary layer which reduces heat loss but current of air can disrupt layer and carry away heat by convection (wind chill) Radiation - *Emission of electromagnetic energy by surface (i.e. sun) *When objects are warmed by radiation, they emit lower-energy radiation as infrared light *The temp of...
