Question

29. Which type of gland discharges fragments of the gland's cells during secretion A. esocrine D apocrine E. holocrine 30 Normal plt for blood is 7.35 to 7.45. Maintenance of the pH in this range is A critical because enzymes work best within narow ranges of pH. B. not critical because extreme pH values do not affect enzyme function C called denaturation. D. not required t. nane ef these choices is correct 31. the three types of protein fbers found in connective tissues are: A hyaluronic acid, collagen, and reticular fibers. 8 proteoglycan, elasin, and reticular fbers C. collagen, elastin, and reticular fibers D. proteoplycan, elattin, and hyalurosic acid If an element is composed of atoms with an atomic number of 6 and a mass number of 14, then a neutral atom of this element contains 32 A. 6 protons B. 6 neutrons C 8 electrons D. 14 protons C. 14 electrons Each of the following statements concerning hydrogen bonds is true EXCEPT, dentiy the exception A Hydrogen bonds are strong attractive forces between hydrogen atoms and negatively charped atoms 8 Hydrogen bonds can occur within a single molecule. C Hydrogen bonds can form between neighboring melecules D. Hydrogen bonds are important forces for holding large molecules together E. Hydrogen bonds are responsible for many of the unique properties of water 34. Facilitated diffusion differs from ordinary diffusion in that faciltated diffusion A expends no ATP B. moves molecules from an area of their higher concentration to their lower concentration. C the rate of molecular movement is limited by the number of available carrier molecules D. never eliminates the concentration gradent E. the rate of molecular movement is not limited by the number of availabie carrier molecules
