What characteristic belongs in the overlapping section of the Venn diagram comparing these kingdoms?
2 / Use the Punnett square to answer the question that follows.

3. / A portion of a nucleic acid is represented by the diagram below.
What conclusion would best explain the absence of thymine from the nucleic acid?
4. / An RNA codon chart is shown.
What is the correct amino acid sequence that is coded from the RNA sequence UGGCAGAUA?
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?
7. / Use the information in the table to answer the question that follows.
Scientific Classification
Kingdom / Animalia
Phylum / Chordata
Class / Reptillia
Order / Testudines
Family / Emydidae
Genus / Terrapine

What is the correct scientific name for the organism classified above?
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?
9. / In the food chain shown, which organism is feeding on a heterotroph? An autotroph?
10. / The diagram below shows an energy pyramid.
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.
