You are a marine biologist sampling an offshore ecosystem. One day, you find a red organism floating in one of your nets. It has structures that resemble the leaves and stems of a plant. You hypothesize that this organism might be photosynthetic. Describe how you could test this hypothesis using a pH indicator solution.
a. In detail, describe the steps you would take and the reactants of photosynthesis required.
b. What change in pH would indicate that the organism was undergoing photosynthesis, and how would the indicator respond?
Which of the following statements is TRUE?
Select one:
A. Lactic acid is a product of aerobic respiration; ethyl alcohol is a product of fermentation.
B. Oxidation is the loss of electrons; reduction is the gain of electrons.
C. Oxygen is a product of cellular respiration; carbon dioxide is a product of photosynthesis.
D. Glucose is a product of aerobic respiration; lactic acid is a product of anaerobic respiration.
