In your experiment, you created two separate systems: cellular respiration in part 1, and photosynthesis in part 2. Explain whether these two separate systems are a good representation of the way cellular respiration and photosynthesis work in the natural world. Can living things survive in a system involving only cellular respiration or only photosynthesis? If not, how could you use similar materials to set up a new experiment that would better model the real world?

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
