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)

the answer is otpion c) understanding

he wants to be heard one more time. he wants to be understood. he needs the truth one more time.

answer;

c. a tree whose roots are surrounded by wet sand.

explanation;

water stress is an important factor limiting the growth and productivity of forests.water stress is the most often cited cause of poor survival and growth of woody landscape plants.

-insufficient soil moisture is the most common form of water stress, but excess moisture that leads to poor soil aeration (hypoxia) can also result in reduced plant vitality. a tree whose roots are surrounded by wet sand would be least likely to experience water stress.

passive transport is a movement of biochemicals and other atomic or molecular substances across cell membranes without need of energy input. unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy.

so, according to what that says, i believe it's hypertonic and hypotonic.

good luck!
