Obligate or strict means and facultative means a. essential or a requirement ability to adapt to or
change b. ability to adapt to or change essential or a requirement 19. A bacterium is described as
a mesophilic microaerophile that grows best in a neutral environment. This means: a. Grows at 3
7 F , requiring O 2 , at pH 7 . b. Grows at 3 7 C , without O 2 , at pH > 7 . c. Grows at 3 7 C ,
requiring small amounts of O 2 , at pH 7 . 20. The events of the growth cycle are: I. Bacteria are
decreasing in number. There is little food left and a lot of waste. II. Bacteria are increasing
rapidly in number. There is moderate food and low waste. III. Bacteria are remaining steady. The
food and waste are equal. IV. Bacteria slowly increase in number. There is a lot of food available
and little waste. The CORRECT order of these events is a.) I, III, II, IV. b.) II, III, I, IV. c.) IV, I,
III, II. d.) II, I, III, IV. e.) IV, II, III, I. 21. A microbe that grows only at the top of a tube of
thioglycolate medium is probably a(n) a. obligate anaerobe b. microaerophile c . facultative
anaerobe d . obligate aerobe 22. Genetic mutations can be a. beneficial b. harmful c. neutral d. all
options are correct
