66. Endosymbiosis theory is accurately described by which of the tollowng? a) it describes the
way in which mitochondria and chioroplasts lest their ability to perform respiration and
photosynthesis b) it describes the way in which eukaryotic cells acquired mitochondia the
mutually beneficial relationship between humans and the microbes that reside in their inside
them c) it describes digestive tracts d) it describes the way in which infected host cells dplay
antigens identifying the pathogens 67 Why are the organisms commonily called \"bluegreen
age\" not classified as true algae? a) They are multicellular b) They are not phototrophs c) They
have chitin in their cell walls d) They are prokaryotic The phytoplankton consist of what 68
Phytoplankton conduct about hai\" or a# photosmnetk actitv on Earth. two groups of microbes?
a) Unicellular algae and plant ike protists b) Unicellular algae and cyanobacteria d)
Cyanobacteria and hicobium species 69. Which phylum of bacteria are capable of forming
endospores? a) Cyanobacteria b) Firmicutes c) Actinobacteria d) Proteobacteria e) Bacteroidetes
70. Some microbes do not normally cause disease, but can infect and cause disease in a host with
a weakened immune system, such as a host suffering from an immunodeficiency. What is the
term for this type of microbe? a) Obligate pathogen b) Primary pathogen c) Opportunistic
pathogen d) Transformative pathogen 71. The phagocytes of the innate immune system are the
only immune cells that directly kill foreign microbes Which of the following are types of
phagocytes? a) Neutrophils b) Macrophages c) Cytotoxic T-cells d) A andB e) A,B,and C 72.
Fungi are capable of multiple types of reproduction. Which form of reproduction would you
expect to observe from a fungus undergoing environmental stress, such as a nutrient shortage or
harsh conditions? a) Fragmentation b) Budding c) Asexual spore formation d) Sexual spore
formation e) Binary fission Page 11
Solution
66. Answer is B. it describes the way eukaryotes acquired mitochondria and chloroplast.
Endosymbiosis is the only theory that explains the evolution of eukaryotes from prokaryotes by
engulfing another prokaryotes that become mitochondia and chloroplast.
67. Answer D. they are prokaryotic
Blue green algae are group of photosynthetic bacteria that term as Cyanobacteria. But algae are
eukaryotes.
68. Answer B. Unicellular algae and cyanobacteria.
69 answer B, Firmicute phylum
