Learning Objective 2: LO 1.1.3 Describe how homeostasis plays a role in everyday activities.
Section Reference 1: Section 1.1 Living Organisms Display Nine Specific Characteristics
Solution: A feedback system requires three components:  1. a stimulus receptor that monitors the environment and reports any changes, 2. a control center that registers the signal from the stimulus receptor and formulates a response, and 3. an effector or effectors to carry out that response from the control center bringing about a change. The response brings the controlled condition back to normal.

Answer: 

Difficulty: Hard
Learning Objective 1: LO 1.2 Explain how life is organized.
Learning Objective 2: LO 1.2.3 Relate taxonomy to human biology.
Section Reference 1: Section 1.2 Human Biology is Structured and Logical
Solution: Organisms are found in one of three domains—the Eubacteria, Archaebacteria or Eukarya. Within the three domains are six kingdoms, four within the Eukarya and one kingdom in each of the other two. Because living organisms appear in a wide variety of forms, we can organize organisms into groups based on similarity of characteristics. Taxonomy is the scheme that allows us to place individuals into broad groups down to more closely related individuals. This organizational system uses the levels domains, kingdoms, phylum, class, order, family, genus, and species.

Answer: 

Difficulty: Hard

Learning Objective 2: LO 1.3.1 List the steps in the scientific method in order.
Section Reference 1: Section 1.3 Scientists Approach Questions Using the Scientific Method
Solution: Answers will vary.  Observation: After administering Drug Y, cholesterol levels went down in human subjects. Hypothesis: Drug Y lowers cholesterol in humans. If blood cholesterol levels are measured after Drug Y is administered to human subjects, then blood cholesterol levels would be lower than before administration of Drug Y. Experiment: Take a large number of human subjects and divide them into two groups. One group is the Experimental group, and the other is the Control group. Measure initial cholesterol levels in both groups. Administer Drug Y to subjects in the Experimental group only. Measure cholesterol levels again in both groups. Data: Collect data from both groups Analysis: See if data supports hypothesis Conclusion: Data either supports or fails to support the hypothesis. Repeat experiment with appropriate modifications.
