Phys 261 lab quiz 2 Questions with
Accurate Answers
molecular motion - ANSWERSreflects the kinetic energy of molecules
is random and erratic
velocity of molecular movement - ANSWERSis lower in larger molecules
increases with increasing temperature
egg 1 in distilled water - ANSWERSgained weight because the concentration of the
egg, 14% is hypertonic to the water. water moves by osmosis from an area of higher
water concentration into an area of lower water concentration
egg 2 in 30% sucrose - ANSWERSlost weight because the concentration of the ff, 14%
is hypotonic to the 30% sucrose solution.
hypertonic solution diagram - ANSWERSwater is being sucked out of cells
isotonic solution diagram - ANSWERSwater is being passed through the cells bloating
them
hypotonic solution diagram - ANSWERSwater is being sucked in the cells
passive processes - ANSWERSaccount for the moent of fats and respiratory gases
through the plasma membrane
passive processes - ANSWERSinclude osmosis, simple diffusion, and filtration
passive processes - ANSWERSuse hydrostatic pressure or molecular energy as the
driving force
active processes - ANSWERSexplain solute pumping, phagocytosis, and pinocytosis
active processes - ANSWERSmay occur against concentration and or electrical
gradient
active processes - ANSWERSmove ions, amino acids, some sugars, across plasma
membrane
epithelium - ANSWERSlines body cavities and covers the body's external surface
muscle - ANSWERSpumps blood, flushes urine out of the bdoy, allowes one to swing a
bat
