You learned about various theories surrounding the determination of one’s sexual orientation. In addition, you learned about some of the limitations and criticisms of the research.

Explain briefly (in 1-2 paragraphs) your understanding of the research on origins of sexual orientation.

Why is it important to understand what determines one’s sexual orientation? Consider ethical, legal, and social implications. If you do not think it is important to understand the origins, please explain.

Based on what you have learned in your readings within the class and your textbook, make a hypothesis as to where you think the research might lead.

Write your initial response to each part in 3–4 paragraphs. Support your arguments with research, applying APA standards to citation of sources.

Consider collision problems. Real-world collisions are rather complicated to capture in full and we approximate them by special cases. Name the two basic collision types we use to describe and idealize real-world collisions. What distinguishes both? In most collision problems we know a) the masses and initial velocities of objects involved in the collision and ask for their final velocities, or b) we know the objects’ masses and aftercollision (final) velocities and ask what their initial velocities were (forensic engineering). Which conservation laws help to mathematically describe collision situations? Name and state them in form of (ansatz) equations. Looking at your answer, explain whether or not these conservation laws are valid for each of the previously named types of collisions.

Detail the theory of budget constraint with an example of your budget constraint.

Memory deteriorates over time. A researcher is interested in discovering a difference between males and females regarding memory retention. He gathered 10 males and 10 females and had each complete a series of memory tests. He then recorded the overall scores for each participant, as shown below. The researcher ultimately believes that Females will retain more memory, and thus score higher on the tests, than males.

Females        Males
77                    87
88                    77
77                    71
90                    70
68                    63
74                    50
62                    58
93                    63
82                    76
79                    65

Over what pH range(s) could valine be used as an effective buffer? Explain your answer, supporting it with what we have discussed about buffers and amino acids

For this project, you will use the provided financial statements for Ford Motor Company. Take the two years given and perform the required financial ratios listed below. First compare the ratios of each company for the past two years to each other, then compare the two companies to each other. In comparing the ratios you will need to discuss which year and which company has a better ratio and why you think that. Justify your rationale and explain your findings in detail in your analysis. Write at least one paragraph discussing your results. Look at 2015 and 2016 financial statements for  Ford Motor Company and General Motors.

1. What is the ratio used for, what is it’s purpose
2. Write out formula
3. Fill out formula using the two years financial statement information for both companies
4. Your interpretation of ratio in at least one paragraph
