Meiosis and Mitosis

Meiosis and Mitosis

Post is of three assignments

1:What are the main differences between meiosis and mitosis? Why did meiosis evolve as an evolutionary strategy? How does this relate to the film “Why Sex?” Why was this reason important to improving survival? Did this information or anything else in the film surprise you and why?

2.) Punnett Square – Complete both problems below.

-Diagram and complete a Punnett square

-Give the phenotype percentages of the offspring

– In dogs, hereditary deafness is caused by a recessive gene (d), while normal hearing is coded by the dominant gene (D). What would be the results if a heterozygous male mates with a heterozygous female? What are the chances that a deaf offspring will result?

– Considering that purple is dominant to white and using P for purple and p for white, draw a Punnett square crossing a heterozygous purple-flowered plant and a white-flowered plant.

3.) Read the section on genes and epigenetics carefully. What are epigenes/epigenetics and how do they differ from genes? Do epigenetics appear similar to any explanations of evolution that were covered in chapter two? If so, please explain the similarities. If lifestyle/environmental factors can affect how our genes work, what are the possible implications? Consider the factors mentioned in your textbook that may affect epigenetics.

4.) How are geography and malaria connected? How/why does the heterozygous condition provide additional protection? What has this additional protection lead to the increase of sickle cell anemia in certain geographic areas? Also, how may certain anthropogenic trends such as deforestation and climate change increase or decrease malaria rates?

2:The Environmental Constraints on Global Pricing Decisions

. Identify some of the environmental constraints on global pricing decisions. The text refers to four types of constraints. I will upload these constraints from our text book in the attachment files. You have to follow them by the order number of the attachment. These constraints are: 1. Currency fluctuations, 2. inflation, 3. Government controls and Subsidies, 4_ Competitive Behavior

Part 2. Explain these and then research external companies/products to illustrate these constraints and how these companies addressed them. You have to find companies that are existed and how these companies addressed them.

3: Alex Poole Strategy

Study Questions

1. Can Starbucks expand beyond the coffee business in a meaningful way without destroying its core coffee retailing business?

2. Can Starbucks create value through its diversification strategy? Will management be able to create valuable, rare, and imperfectly imitiable economies of scope through its expansion into juice, tea, pastry, and new distribution channels or will the expansion be the downfall of Starbucks as it was in 2008?

3. Do competitors represent a significant threat to Starbucks competitive advantage through their additions of customized, higher quality coffees to their menus?

4. Should Alex Poole sell his Grandma’s Starbucks stock or keep it in her portfolio?

Sentences 1&2 – Your conclusion and/or recommendation for management (5 points)
Remaining Sentences of the PO – supporting course concepts (20 points) and analysis with evidence — persuasive qualitative or quantitative facts or interpretations of them (20 points) — that confirms your position and refers to the attached exhibits written essay style in a total 300 words. Analysis and overall effectiveness will account for 40 points of your score. Formatting is worth 5 points, and writing style accounts for 10 points of the assignment.
Exhibits – calculations, graphs, tables showing the use of course frameworks such as Porter’s Five Forces, VRIO, financial analysis (not included in word count)
The PO should present your main idea(s) about the case for discussion. In other words, give me what you think is important about the case. Do not summarize or review the events of the case. After you read the case, determine the central issue or issues management needs to address.
The PO should not contain:
§ a recitation of case events or facts;
§ bullet points or lists of any kind;
§ section headers;
§ passive voice;
§ unsupported assumptions and opinions from personal experience;
§ more than 300 words excluding exhibits, your name and other administrative details (course number etc…); or
