1. Describe the fluid mosaic model of the plasma membrane. Discuss the role of the membrane in the movement of materials through it by each of the following processes.
   1. Active transport
   2. Passive transport

2. Describe negative and positive feedback loops, and discuss how feedback mechanisms regulate each of the following.
   1. The menstrual cycle in a nonpregnant human female.
   2. Blood glucose levels in humans.

3. Discuss the adaptations that have enabled flowering plants to overcome the following problems associated with life on land.
   1. The absence of an aquatic environment for reproduction
   2. The absence of an aquatic environment to support the plant body
   3. Dehydration of the plant

If you found a prototype of a revolutionary new mobile phone lying on a public bench, what would you have done with it? What would be the consequences of your chosen action? Does the value of a parcel of land come only from the profits it can generate? If not, what makes land valuable? Does it have an “inherent” value that has nothing to do with human profit? How is intellectual property a true form of property? Do you think it is appropriate for governments to protect intellectual property just like any other form of property? Explain your answer.

1. Many economists believe that you cannot judge the usefulness of a theory based on the realism of its assumptions, and so the standard assumption that people are motivated by “rational self-interest” should not be dismissed so easily. Yet behavioral economists claim to have solid evidence that contradicts the assumption of “perfect” rationality. But the authors of the textbook dispute the validity of that evidence. For each of the following, briefly explain their arguments:

1. The reliance on laboratory studies (6)

2. The human brain’s internal inclination to correct bad decisions (6)

3. Errant decisions, entrepreneurs, and market pressures (6)

1. When an allele becomes more common in a species, what changes?

2. Which word describes what happens when different populations of the same species develop different allele frequencies?

3. What is a biological race?

The integumentary system is an essential organ system, separating the external environment from the internal environment of the human body. As such, this system protects the body from the invasion of harmful substances, helping to maintain homeostasis. There are many medical procedures that affect the integumentary system, including hair transplants, lipoplasty, rhytidectomy, chemical peels, and collagen injections.

Pick an integumentary procedure, from the list above or from another procedure of your choice, and describe it. Describe the reasons an individual would undergo the procedure and any possible complications. Explain the direct and indirect effects the procedure has on the integumentary system.

1. Explain the difference between incomplete dominance and codominance.
2. A man with blood type A marries a woman with blood type B. One of their children has blood type O. Show how this is possible.
3. What are polygenic traits? Give an example of a polygenic trait in humans (besides skin color).
4. A male human is heterozygous for detached earlobes (Ee) and could produce sperm that contain either the dominant gene (E) or recessive gene (e). Does this occur during meiosis or mitosis?
5. Linked genes are on ( the same / different ) chromosome(s) and tend to be inherited ( together / separately).

Choose a company whose policies or actions have allegedly violated the rights given to employees under the law. A source for current cases can be the National Labor Relations Board or Equal Employment Opportunity Commission. Analyze the employer’s actions that resulted in the case. What substantive right have they allegedly violated? How were they violated? What action should the company take to mitigate or prevent this situation in the future? Assuming you are the human resources manager, outline a plan for legal compliance.

Rational choice theory became an approach to address many questions about human behavior outside the discipline of economics from whence it derived. Rational choice came to address many positive questions, reducing them to issues surrounding what a person will do when presented with certain choices.

Discuss the strengths and shortcomings of the predictive model of rational choice theory in realms of positive social science and normative social inquiry. What types of questions might be left unanswered by this approach? What does your response say about the value of predictive social science?
