| Question | Answer |
|---|---|
| 1.1a Are tigers carnivores, herbivores, or omnivores? | Carnivores-Tigers only eat meat; thus they are carnivores. |
| 1.1b Are cows carnivores, herbivores, or omnivores? | Herbivores-Cows eat grass. This makes them herbivores. |
| 1.1c Are humans carnivores, herbivores, or omnivores? | Omnivores-Humans eat plants and meat. This makes us omnivores. |
| 1.1d Are sheep carnivores, herbivores, or omnivores? | Herbivores-Sheep graze on grasses. This makes them herbivores. |
| 1.2a Are rose bushes producers, consumers, or decomposers? | Producers-Rose bushes have green stems and leaves to produce food via photosynthesis. |
| 1.2b Is yeast (a fungus) producers, consumers, or decomposers? | Decomposers-Almost all fugi are decomposers. |
| 1.2c Are lions producers, consumers, or decomposers? | Consumers-Lions depend on other organisms for food. |
| 1.2d Are humans producers, consumers, or decomposers? | Consumers-Humans depend on other organisms for food. |
| 1.3 A biologist studies an organism and then two of its offspring. They are all identical in every possible way. Do these organisms reproduce sexually or asexually? | These orgamisms reproduce asexually. If they reproduced sexually, the offsprings' traits would be a blend of both parents' traits. Since these offspring are identical to the organism that produced them, this must be asexual reproduction. |
| 1.4 When trying to convince you of something, people will often insert "Science has proven..." at the beginning of a statement. Can science actually prove something? Why or why not? | Science cannot prove anything. The best science can say is that all known data support a given statement. However, since all data come from experiments which might be flawed, there is no way that science can prove anything. |
| 1.5 A scientist makes a few observations and develops an explanation for the observations that he has made. At this point, is the explanation a hypothesis, theory, or scientific fact? | It is a hypothesis. The explanation will have to be tested with a significant amount of data before it can even be considered a theory. |
| 1.6 Suppose you chose two organisms at random out of a list of the mebers of kingdom Plantae, then you chose two organisms at random out of a list of the members of family Pinacae. in which case would you expect the two organisms to be the most similar? | Since family is several steps down from kingdom, the organisms in the same family should be much more similar. |
| 1.7 You compare several organisms from different orders within a given class. You then compare organisms from different classes. In which case would you expect the differences to be greatest? | Since class is one step higher than order, the organisms from different classes should have more differences. |
| 1.8 An organism is made up of one eukaryotic cell. To what kingdom does it belong? | Protista-This kingdom has the single-celled eukaryotes. |
| 1.9 An organism is multicellular and an autotroph. To what kingdom does it belong? | Plantae-Almost all autotrophs belong in this kingdom. |
| 1.10 An organism is multicellular with eukaryotic cells. It is also a decomposer. To what kingdom does it belong? | Fungi- Most decomposers are in this kingdom. |
