What is Fick's Law? What influences diffusion - Answer-The molar flux due to diffusion is proportional to the concentration gradient F=kA((c1-c2)/d)) - Answer-F is rate of diffusion K is diffusion constant A is surface area for diffusion D id distance for diffusion (ex: membrane thickness) C1-C2 is difference in concentration How does the diffusion of uncharged and charged particles differ? - Answer-Uncharged particles diffuse irrespective of the concentration of each other. Charged par...

BIO 320 EXAM 2 STUDY GUIDE SOLUTIONS Describe all processes by which organisms exchange heat with their environment. - ANSWER- Radiation, Conduction, Convection, Evaporation Radiation - ANSWER-*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 the radiating surface determines how rapidly an object loses energy by radiation to colder parts of the environment. Conduction - ANSWER-*...

What are the components of extracellular fluid? - answer-Interstitial fluid and Plasma What are the two types of glands? - answer-Exocrine and Endocrine Glands What are glands? - answer-derived from epithelial tissue, specialized for secretion (chemicals/hormones) Endocrine Glands - answer-ductless glands that secrete hormones directly into the blood stream Exocrine Glands - answer-glands that secrete products through ducts to the outside of the body or into a cavity that communicate...

1. Secretion of K+ by the distal tubule will be decreased by (A) metabolic alkalosis (B) a high-K+ diet (C) hyperaldosteronism (D) spironolactone administration (E) thiazide diuretic administration The answer is D Distal K+secretion is decreased by factors that decrease the driving force for passive diffusion of K+ across the luminal membrane. Because spironolactone is an aldosterone antagonist, it reduces K+ secretion. Alkalosis, a diet high in K+, and hyperaldosteronism all incr...
