21. Which statement best describes how sugars are metabolized in herbivores that eat clover containing high levels of cyanide?
A. Fermentation and the Krebs cycle metabolize sugars and produce
sufficient ATP to sustain life.
B. Aerobic respiration and photosynthesis partially metabolize sugars and
store metabolic intermediates until the levels of cyanide are reduced.
c. Glycolysis metabolizes sugars more efficiently than it does in the
absence of cyanide and produces the normal amount of ATP per sugar
molecule.
D. Glycolysis and fermentation metabolize sugars but do not produce
sufficient ATP to sustain life.

Juan and carol were studying invertebrates in biology. they knew that segmented or earth worms preferred a dark, moist habitat. during this lab, they would be investigating the responses of organisms called planaria or dugesia tigrina. these were simple flatworms that still had a one-way digestive system and a very simple nervous system. juan and carol placed the planaria in a petri dish containing cool, distilled water that was partially covered with black paper. they shined a light on the dish. next, they removed the paper and placed a small amount of chicken liver at one end of the dish. they added a few large salt crystals to the water. finally, they added drops of hot water to the cool water in the petri dish. their results can be seen in the data table. according to their experiment, all but one conclusion is valid.

Which of the following matches the organisms described with the correct domain? a. archaea--multicellular, eukaryotic organisms that do not have cell walls b. eukarya--single-celled and multicellular organisms, with a defined nucleus and a variety of nutritional sources c. bacteria--unicellular, eukaryotic organisms with cell walls that do not contain peptidoglycan d. bacteria--unicellular, eukaryotic organisms that always lack cell walls
