3. 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? (3 points)

"d.) carbon dioxide and hydrogen sulfide"

within 30 of the equator hope this

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community

explanation:

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
