Angraecoid orchid flowers have a long, tubular
throat, while African moths have long probosci for
gathering nectar. The orchids are dependent on the
moth for pollination, while the moths are
dependent on the orchids for nectar. Which pattern
is best represented by this pair of organisms?
A. coevolution
B. adaptive radiation
C. convergent evolution
D. divergent evolution
Why is angiosperm reproduction so effective?
A. Seeds are their only form of reproduction.
B. Their seeds are uncovered and easily spread.
C. They reproduce through both sexual and
asexual reproduction.
D. Their leaves and stems contain many sporeproducing structures.
How do viruses, such as the tobacco mosaic virus,
infect plants?
A. They enter the plant through insect bites or
wounds.
B. They enter the plants through osmosis in leaf
cells.
C. They are absorbed through the stomata of the
leaves.
D. They are absorbed through the roots of the host
plant.
Which species most likely coevolved with
flowering plants?
A. bees
B. Deer
C. Squirrels
D. non-flowering plants
Which adaptation would be most beneficial to a
mammal in reducing its body temperature?
A. oil glands
B. sweat glands
C. increased muscular movement
D. decreased blood flow to appendages
More than 300,000 Americans have died from
AIDS since 1981. However, the virus that causes
AIDS does not directly kill the host. Which best
explains how this virus leads to the eventual
death of the host?
A. The virus destroys nerve and brain cells.
B. The virus affects muscle cells, which
eventually weakens the heart.
C. The virus weakens the immune system,
allowing for opportunistic diseases.
D. The virus causes a loss of respiratory function,
leading to the inability to breathe.
Which characteristics have many butterflies acquired
through evolution to defend themselves against birds?
A. Butterflies have developed larger wings, so they can fly
fast and escape the birds.
B. Butterflies have developed marks on their wings that
look like eyes and confuse the birds.
C. Butterflies have developed larger antennae so they can
detect birds before they get too close.
D. Butterflies have developed a proboscis that can sting
birds with a toxin that prevents the birds from wanting to
eat them.
Which mechanism is used by many fruit-bearing
plants to spread seeds?
A. sporulation
B. wind dispersal
C. water dispersal
D. animal consumption
Why do some people who are vaccinated
against influenza (the flu) still contract the virus?
A. The vaccine does not cover all strains of
influenza mutations.
B. The vaccine may have been given as a nasal
spray rather than an injection.
C. People who receive the vaccine and have not
had the influenza virus previously are not
protected.
D. People who have had the influenza virus and
also receive the vaccine are the only ones who
are protected.
Which would most likely occur in an aquatic protist
population that relied on a declining supply of decaying
matter for energy?
A. Genetic alterations would be minimal, and the
protists would begin to consume each other.
B. Genetic alterations of the protists may give some the
ability to gain nutrition through photosynthesis.
C. Over time, the protists would develop the ability to
utilize freshwater as their primary source of nutrition.
D. Over time, the protists would become complex
multicellular organisms with increased mobility to feed
on terrestrial organic matter.
