True or False. Adaptations are genotypic and long-term, while acclimations are
phenotypic and short-term. - ANSWERS True.
You are given an organism to identify. It has a fruiting body that contains many
structures with eight haploid spores lined up in a row. What kind of a fungus is
this?
A.
ascomycete
B.
basidiomycete
C.
deuteromycete
D.
chytrid
E.
zygomycete - ANSWERS A.
,ascomycete
Why is it more difficult to treat fungal infections than bacterial infections in
humans?
A.
Fungal and animal cell proteins are similar. Thus, drugs that disrupt fungal cell or
protein function may also disrupt human cell or protein function.
B.
Most fungi are multicellular and thus the drugs required to treat a fungal infection
must be able to kill several types of cells; bacteria, on the other hand, are
unicellular and thus simpler to kill.
C.
Fungi are larger organisms than bacteria and thus require stronger drugs to stop
an infection.
D.
Fungi are able to mutate more quickly than bacteria, so they quickly develop
resistance to antifungal drugs. - ANSWERS A.
Fungal and animal cell proteins are similar. Thus, drugs that disrupt fungal cell or
protein function may also disrupt human cell or protein function.
Fungi that absorb nutrients from decaying plant matter are called ________.
A.
mycorrhizae
, B.
molds
C.
mushrooms
D.
saprobes
E.
yeasts - ANSWERS D.
saprobes
Among protostomes, which morphological trait has shown the most variation?
A.
type of symmetry (bilateral vs. radial vs. none)
B.
number of embryonic tissue types (diploblasty vs. triploblasty)
C.
type of development (mouth first vs. anus first)
