weinbrenner bio 1040 dynamic study modules exam 1
1.Which of the following are characteristics of endospores?: -can resist trau-
ma, including boiling water
-dehydrate butas can rehydrate if external conditions improve
-can remain dormant for decades
2.One warm summer day, your uncle cuts up a big batch of chicken parts to barbecue,
but then he is called away for a work-related emergency. When your aunt makes the
salad several hours later, she uses the knife that your uncle left unwashed next to the
sink. What might happen to you later that night, and why?: food poisoning due
to Salmonella
3.Which of the following states an important difference between plasmodial slime
molds and cellular slime molds?: Plasmodial slime molds are unicellular; cellular
slime molds can swarm as a brief multicellular state.
4. live within and provide energy for the reef-building coral ani- mals,
whose efforts support diverse and beautiful coral reef communities.: -
Dinoflagellates
5.What structural elements are present (or absent) that enable some members of
1/
20
,Archaea to thrive and reproduce in extreme environments?: unusual proteins and
specific molecular adaptations
6.Giardia intestinalis, Trichomonas vaginalis, and members of Trypanosoma share one
characteristic that allows them to thrive inside our bodies. What is it?: the ability to use
anaerobic pathways for energy
7.The life cycles of land plants and many multicellular algae include the alternation
of generations. What does this mean?: A multicellular diploid form alternates with a
multicellular haploid form.
8.Which of the following protists is autotrophic, has a unique glassy cell wall, is
buoyant, and is a key food source in freshwater and marine environments?-
: diatoms
9.Biofilms can make urinary tract or ear infections particularly hard to treat. Why?:
The biofilm resists penetration by antibiotics.
10.How are liquid wastes handled in a water treatment facility?: They are sprayed
onto rocks covered with biofilms of aerobic bacteria and fungi.
11.You collect samples of soil from a nearby field and isolate and sequence the DNA of
several microorganisms you find there. This information will help you construct a
of the field.: microbiome

, 12.Most endosymbionts are proteobacteria and are . Streptococ-
cus and Staphylococcus are .: gram-negative: gram-positive
13.Which of the following is not a true statement about protists?: They have a single
strand of circular DNA.
