1. Kingdoms – Give an example of each

This section asks for examples of organisms from each kingdom. The table is already filled out with examples:

| Kingdom | Examples |
|---------------|-----------------------------------|
| Animalia | cat, dog, fish, bird, frog |
| Plantae | tree, flower, corn, tomato |
| Fungi | mushroom, yeast |
| Eubacteria | E. coli, Salmonella |
| Archaea | Extremophiles |
| Protists | Amoeba, paramecium, euglena |

Explanation:
- Animalia: Multicellular, heterotrophic organisms.
- Plantae: Photosynthetic, multicellular organisms.
- Fungi: Heterotrophic, often filamentous or unicellular.
- Eubacteria: Prokaryotic, single-celled organisms.
- Archaea: Prokaryotic, often extremophiles (living in extreme environments).
- Protists: Unicellular or simple multicellular eukaryotes.

---

2. Into what kingdom would each of the following be classified?

This section requires classifying organisms based on their characteristics.

#### a. Unicellular prokaryotes that live in dust.
- Answer: Eubacteria
- Explanation: Prokaryotes are single-celled organisms without a nucleus, and those living in dust are typically bacteria.

#### b. Unicellular eukaryotes that line in pond water.
- Answer: Protista
- Explanation: Protists include unicellular eukaryotes like amoebas and paramecia, which can be found in pond water.

#### c. Multicellular eukaryotes that live all over the planet and consume food.
- Answer: Animalia
- Explanation: Animals are multicellular, heterotrophic eukaryotes that consume food.

#### d. Unicellular prokaryotes that live in volcanic ash.
- Answer: Archaea
- Explanation: Archaea are prokaryotes adapted to extreme environments, such as volcanic ash.

#### e. Multicellular eukaryotes that have cell walls and are heterotrophic.
- Answer: Fungi
- Explanation: Fungi are multicellular eukaryotes with cell walls and are heterotrophic (they decompose organic matter).

#### f. Multicellular eukaryotes that have cell walls and are autotrophic.
- Answer: Plantae
- Explanation: Plants are multicellular eukaryotes with cell walls and are autotrophic (they perform photosynthesis).

3. Organisms that belong to the same class must belong to the same:

This question asks about the hierarchical relationship in taxonomy.

- Answer: Phylum, Kingdom
- Explanation: In the taxonomic hierarchy, organisms in the same class must also belong to the same phylum and kingdom. However, they do not necessarily belong to the same order or family.

---

4. Fill in the blanks:

This question asks for the correct order of taxonomic ranks.

- Kingdom → Phylum → Class → Order → Family → Genus → Species
- Answer: Phylum, Order, Family, Species

---

5. In each pair, circle the one that you would expect to find the most individual species:

This question tests understanding of the taxonomic hierarchy. The broader the classification, the more species it contains.

#### a. Kingdom & Genus
- Answer: Kingdom
- Explanation: A kingdom is a much broader category than a genus, so it contains many more species.

#### b. Phylum & Kingdom
- Answer: Kingdom
- Explanation: Similarly, a kingdom is broader than a phylum.

#### c. Class & Family
- Answer: Class
- Explanation: A class is broader than a family.

#### d. Order & Phylum
- Answer: Phylum
- Explanation: A phylum is broader than an order.

#### e. Genus & Order
- Answer: Order
- Explanation: An order is broader than a genus.

#### f. Phylum & Class
- Answer: Phylum
- Explanation: A phylum is broader than a class.

#### g. Genus & Species
- Answer: Genus
- Explanation: A genus is broader than a species.

6. Which three animals is the tiger most closely related to?

This question uses the provided scientific names chart to determine relationships.

- Tiger: Panthera tigris
- Jaguar: Panthera onca
- Leopard: Panthera pardus
- Lion: Panthera leo

Since all these animals share the genus Panthera, they are most closely related.

- Answer: jaguar, leopard, lion

---

7. Would you expect an animal with the name Rania onca to look similar to a mountain lion?

This question involves analyzing the scientific name and comparing genera.

- Rania onca: This name is incorrect; the correct name is Panthera onca (jaguar). Since it belongs to the genus Panthera, it would look similar to other members of this genus, including the mountain lion (Puma concolor), but not exactly the same because they are different species.

- Answer: No
- Explanation: It is not the same genus (Panthera vs. Puma).

8. Which animal is the house cat closest to?

This question uses the scientific names chart to determine the closest relative.

- House cat: Felis catus
- African wild cat: Felis lybica

Both belong to the genus Felis, making them closely related.

- Answer: African wild cat
