Exam 1 (Ch 21-27)- Week 4
Q # 1 (2.5 point)
Some slime molds have some morphological similarities to
fungi such as during times of stress they will develop into
fruiting bodies that produce spores. However, DNA analysis
doesn't indicate a direct common ancestor, but it is thought
that the similarities are due to environmental pressures,
which is an example of
Q # 1 option: vestigial
structures
homologous
structures
divergent evolution
convergent
evolution
Q # 2 (2.5 point)
What was the major event that marks the Ordovician period
more than 500 million years ago?
Q # 2 option:
appearance of green algae in the fossil record
colonization of land by ancestors of modern land
plants the evolution of flowering plants
,appearance of the first gymnosperms
, Q # 3 (2.5 point)
Which fungus has often served as a starting point for
identifying and studying genes that were then discovered in
humans?
Q # 3 option:
Saccharomyces cerevisiae
Penicillium notatum
Escherichia coli
Agaricus campestris
Q # 4 (2.5 point)
How did the evolution of seed plants change the different
forms in the life cycle of plants?
Q # 4 option:
dominant gametophyte generation and microscopic
sporophyte within gametophyte
dominant sporophyte generation and microscopic
gametophyte within sporophyte
dominant sporophyte generation with large, separate
gametophyte bodies
dominant gametophyte generation with large, separate
sporophyte bodies
Q # 5 (2.5 point)
