Explanation:

1. A hypothesis is a proposed explanation made on the basis of limited evidence as a starting - point for further investigation. James' statement about plants growing better in sunlight is a hypothesis.
2. Zoology is the branch of biology that studies animals. Since the scientist is studying lemurs (a type of animal), the branch is zoology.
3. In binomial nomenclature, the scientific name of an organism consists of a genus name and a species name. For Balaenoptera musculus, musculus is the species name.
4. Deductive reasoning starts with general statements (all birds have wings) and applies them to a specific case (a flamingo is a bird), concluding that the specific case has the characteristic (a flamingo has wings).
5. The first step in the scientific method after identifying a problem is to gather information.

Answer:

1. a. hypothesis
2. b. zoology
3. c. musculus
4. b. deductive reasoning
5. c. Gather information
