Mike has four aquatic plants of the same size and the same species. He submerges the plants in a separate beaker filled with 200 ml of water. She then sets each beaker under a different intensity of light. Mike observes that, of the four plants, the plant in the beaker under the most intense light gives off the most gas bubbles in a 20 minute period.

Which of the following statements best explains Mike’s observations?
a)
Cells decompose most quickly under the most intense light.
b)
Water evaporates from plants faster under the most intense light.
c)
Photosynthesis occurs at the highest rate under the most intense light.
d)
Gases in the leaves of plants expand most under the most intense light
25.
Which of the following are the reactants of photosynthesis?
a)
water and glucose

26.
A weightlifter is using heavy weights in short bursts for a competition. Because his muscle cells are not able to take in enough oxygen to make very much ATP the weightlifter begins to get fatigue in his muscles. Which of the following processes is most likely going on in the muscles of the weightlifter as he competes in his event?
a)
As the cells run out of oxygen they switch to anaerobic respiration (fermentation), which allows the cell to make small amounts of ATP in the absence of oxygen.
b)
As the cells run out of oxygen, they die off gradually and the weightlifter's muscles have fewer contracting muscle cells.
c)
The cells will never run out of oxygen if the weightlifter is breathing.
d)
As the cells run out of oxygen, they will continue to make the same amount of ATP, since oxygen is not required to make ATP.
27.
Two different species of bacteria are examined. Scientists find that species X always produces CO2 and H2O during cellular respiration. Species Y always produces ethyl alcohol and CO2. Which conclusion can be made from these observations?

Only species Y is anaerobic
c)
Both species X and Y are aerobic.
d)
Both species X and Y are anaerobic.
28.
Why are there less air bubbles as the plant is place further away from the light source
a)
because cellular respiration decreases when there is less light
b)
because the light independent reaction decreases when there is less light

d)
the wavelength increases as a plant is placed further away from a light source
