Which of the following describes the phylogenic relationships
between the three domains?
a. Bacteria and archaea are more closely related to each other
than Eukarya
b. Archaea is the most ancestral of the domains, bacteria is
closest to Eukarya
c. Eukarya is the most ancestral domain, while archaea is the
most recent one
d. Bacteria is the most ancestral domain, followed by archaea
and then Eukarya
2. Human papillomavirus (HPV) is very common males and
females. Although most infections are cleared within a few weeks,
there are two HPV types that have severe long- term effects and are
responsible for 70% of all cervical cancers. How can some viruses
be related to cancer?
a. The virus forces the cells to produce more viruses and this
always results in cancer
b. The virus lyses the cell as it exists the cells and this
makes the cell become cancerous
c. The virus incorporates its genetic information in the hosts
chromosome alternative
d. All viruses regardless of their lytic or lysogenic cycles
cause cancer
3. The invention of vascular tissues was a great adaptation to
colonize terrestrial environments. However, many vascular plants
still require water to reproduce sexually.
What innovation allowed plants to reproduce without
water?
a. The evolution of flowers, only flowering plants can
reproduce without water
b. The evolution of pollen, gymnosperms and angiosperms can
reproduce without
water
c. The dominant sporophyte generation that can produce spores
by meiosis
d. The dominant gametophyte generation that can produce
gametes by mitosis
4. As we progress from bryophytes to angiosperms, what is
happening to haplodiplontic cycle?
a. The gametophyte generation becomes more prevalent
b. The gametophyte generation disappears
c. The sporophyte generation becomes more prevalent
d. The sporophyte generation disappears.
5. All of the following are considered evolutionary advantages
of seeds EXCEPT:
a. They allow for a period of dormancy when conditions are
unfavorable
b. They can have modifications of the seed coat that can
promote dispersal of
offspring
c. They help attract pollinators
d. They provide protection to the embryo
e. They development is not limited by sperm having to swim
through water to reach
the egg
