The amount of oxygen produced can be quantified in order to determine the rate of photosynthesis. Elodea leaves are divided into little pieces, and the cut ends are put into the funnel's stem.
<h3>What did Elodea's bubbles in this experiment represent?</h3>
The bubbles that you observe rising from an elodea cutting's leaves are actually a result of the photosynthesis process. In some types of algae and in plants, photosynthesis takes place. In the process, light energy is changed into a sort of chemical energy that is then stored as sugar.
<h3>What substance did we use to examine whether photosynthesis existed in Elodea?</h3>
To test whether photosynthesis and/or other processes are occurring, you will conduct experiments using the dye Phenol Red in this exercise. In Elodea plants, cellular respiration is taking place. The experiments look into how light affects these processes.

Because water is a polar molecule, it makes an excellent solvent for polar and ionic compounds found within cells and tissues.
Answer:B)
Explanation: animals store glucose as glycogen (which is found in the liver), and plants store it as starch
A. A farmer crosses two kinds of corn. He produces a new, better tasting type of corn.
Answer:
B.Wolves reintroduced --> elk decline --> willows increase --> beavers increase
Explanation:
Interrelatedness can be observed in the ecosystem of Yellowtone, in which species interaction is key to maintaining a balance in the ecosystem. Option B represents a correct example of interrelatedness.
Wolves prey on elk, thereby reducing the population of elk they browse on willows. The control of the population of elk would lead to the increase of willows as well as allow for their massive growth. These willows are very important to beavers. More willows would mean more beavers. Beavers gnaw on huge willows which they use in constructing dams to slow down water flow. Beavers do not really love rivers that flow fast, and so rely on willows to make dams.
