What happens if you place human red blood cells in a concentrated salt solution? they shrink as water moves from inside to outside the cells as a result of osmosis. they burst as water moves from outside to inside the cells as a result of osmosis. no change occurs as water freely diffuses back and forth across the cell membranes. the cells expend energy pumping water out in response to the greater external salt concentration.

The lake of the ozarks is a human-made lake, so it collects runoff from coal strip-mining, fertilizers, resort wastewaters, and septic drainages. the average lake temperature is between 10∘c and 21∘c. consider the physical requirements for growth and multiplication that would allow fecal coliforms to “blossom” in the lake of the ozarks. which of the following would accurately describe these organisms? check all that apply. psychrophiles facultative halophiles extremophiles mesophiles hyperthermophiles
