5. The diagram shows a cellular process in which a double-stranded molecule of nucleic
acid gives rise to a single-stranded molecule of nucleic acid.
Which best describes the process shown?
6. Taxonomy, the science of classifying living things, is based on related organisms having similar
structures or patterns evident at some level of observation. The drawings represent organisms that
are related.
Which organizational pattern do the organisms share?

8. This food chain diagram shows some predator-prey relationships in a wetland ecosystem.
Plants → Insects → Small Fish → Frogs → Wading Birds
Based on the diagram, if the population of frogs were to increase, which populations of
organisms would immediately begin to have fewer individuals?

The diagram below shows an energy pyramid.
Page 4/7
Some energy is lost as it is transferred from one level of the
pyramid to the next. At what level will the total amount of
usable chemical energy be approximately 10% of the amount
found at Level 3?
11. How many trophic levels do food
pyramids based on most
ecosystems have?
12. A food web shows an arrow that
points from a frog to a fly. What
does the arrow indicate?
13. If a newly found species were
eukaryotic, multicellular, and
autotrophic, to which kingdom would
it belong?
14. Organisms with cell walls made
of chitin belong to which kingdom?
15. A stream changes course so a
population of beetles is subdivided
into two populations. The woods on
the western side of the stream
contains a land predator that is
absent on the eastern side of the
stream. What will most likely happen
to the population of beetles over
many generations?

16. Define genetic drift.
17. What scientist presented
evidence that species evolved from
a single common ancestor through
the process of natural selection?
18. The steps of a biological process
are listed.




Overproduction of offspring
occurs.
Genetic variation is expressed.
Individuals struggle to survive.
Only certain individuals
successfully reproduce.
What biological process do these
steps describe?
19. How would you describe how
genetic information moves from
DNA in the nucleus to the ribosomes
in the cytoplasm?
20. You observe a cell under a
microscope and find that it contains
membrane-bound organelles? How
would you classify the cell?
21. Write the equation that describes
the net process of photosynthesis.
22. What organelle is responsible for
making ATP in the cell?
