Chapter 1 1) Pasteur’s experiments proved that A) Cells cannot survive in swan necked flasks B) In order to grow, cells need to be supplied with oxygen C) Spontaneous generation can only occur if nutrient broth is left open to the environment D) Sterilizing nutrient broth prevents spontaneous generation E) Pre-existing cells present in the air can grow in sterilized nutrient broth Answer: E Bloom's Taxonomy: Knowledge/Comprehension 2) Recall Pasteur's experiment on spontaneous generation. If he had just warmed the nutrient rich broth, rather than boiled it, what would have been the likely outcome of his experiment? Cells would . A) not have appeared in either flask B) have appeared in both flasks C) have appeared in the swan-neck, but not the straight-neck flask D) have appeared in the straight-neck, but not the swan-neck flask Answer: B Bloom's Taxonomy: Application/Analysis Section: 1.2 3) Spontaneous generation . A) was demonstrated to occur under normal laboratory conditions by Pasteur B) apparently occurred at least once—when life on Earth began C) occurs every time a new species evolves from a preexisting species D) addresses the formation of new cells from existing cells Answer: B Bloom's Taxonomy: Knowledge/Comprehension Section: 1.2 4) What is the process component of the theory of chemical evolution? A) Acid-base reactions resulted in the formation of large, complex organic molecules. B) Kinetic energy was transformed into chemical energy. C) During polymerization reactions, hydrolysis was completed with condensation. D) The process occurred at black smokers, in the atmosphere and oceans, or in outer space.
