Suppose you have a trait in which males exhibit the trait with much greater frequency than females. Females can pass the trait to all of their offspring even if they themselves don’t exhibit the trait while males pass the trait to only their female offspring. A) Explain what pattern of inheritance is described in this scenario. B) Give a specific example of a genetic trait that shows this pattern of inheritance. C) If you have a female offspring that exhibits a trait with this pattern of inheritance, what can you conclude about the genotypes of her parents? D) If you have a man that exhibits a trait like this, who is married to a woman whose father also exhibited a trait like this, what would be the expected phenotype ratios of their offspring? E) SHOW YOUR WORK.

Water has a number of unique properties that sets it apart from other substances, sometimes called the “anomalies of water.” The most commonly recognized anomalies are: The match between the range of temperatures of liquid water and the “normal” temperatures on earth. Water’s high specific heat (and therefore water’s good coolant/”temperature buffer” properties). Water’s “universal solvent” properties (ability to dissolve a wide range of different substances). The lower density of ice vs. liquid water (the fact that water “expands when freezing”). Water’s high cohesion and high surface tension (its property of “sticking together” strongly, forming droplets and making water surface resist being stretched or broken). Pick 1 of these properties and learn more about how it canbe explained from the viewpoint of attraction forces between molecules and/orother physical properties of water, as well as the significance of these properties for life on earth. You can use the textbook and any other online materials, though you may want to review the articles in the Additional Materials folder of this module/week. Based on the information you have learned, write a thread about 1 of the anomalies, referencing your sources and address the following points: How is the anomaly explained from the viewpoint of the properties of water molecules (if it is relatively clear)? What is the significance of these properties for life on earth? Or, what is the significance for the functioning of the human body? How does this property of water reflect (or play into) God’s design of earth and life?

Lou Barlow, a divisional manager for Sage Company, has an opportunity to manufacture and sell one of two new products for a five-year period. His annual pay raises are determined by his division’s return on investment (ROI), which has exceeded 23% each of the last three years. He has computed the cost and revenue estimates for each product as follows:

Case Study

Assessment of the nutritional quality of Mrs. Anderson’s diet

Mrs. Anderson is 58 years old. She lives alone in her house in Orleans, Ontario. Her husband died six months ago. She worked as a manager for several big retail stores for about 20 years before retiring 1 years ago. She has two children, a 34-year-old daughter and a 32-year-old son and 3 grandchildren. They live in the Montreal and Toronto.

A few weeks ago, Mrs. Anderson fell and broke her wrist. Her attending physician referred her for a bone density assessment using bone densitometry. This test revealed that Mrs. Anderson suffers from osteoporosis. Her doctor used this visit as an opportunity to perform a complete routine examination. Laboratory results show that her blood cholesterol and blood pressure are marginally high.

Mrs. Anderson's doctor suggests that she consults a dietitian in private practice to obtain a nutritional evaluation of her diet but also to obtain specific nutritional advice related to her health problems. You are an intern (4th year) at Myriam Lavallée’s clinic. She decides to entrust you with Mrs. Anderson. Myriam has already had a first meeting with Mrs. Anderson for 60 minutes. During this first interview, she took her anthropometric measurements (height and weight) and did a dietary history to obtain an overall picture of her eating habits.

Myriam shares with you some of the information she has collected about Mrs. Anderson. The dietitian noted that some aspects of Mrs. Anderson's eating habits need to be improved. She prefers not to reveal her observations at this time as not to influence your own analysis! However, she shares with you that Mrs. Anderson's food pattern is very similar from one day to the next and that her eating habits have changed since her husband's death. Her main physical activity is limited to taking a walk with her small dog Nikko for about 15 minutes in the park near her home only when the weather is nice. During the winter, she walks to the neighbourhood shopping centre (1-2 times a week). She never smoked and she drinks alcohol only on occasions such as holidays and birthdays. It is then limited to 1-2 drinks. Mrs. Anderson feels lonely since she lives on her own. She does not really have any social activities and her children and grandchildren come to visit her about once a month in turn.

In order to analyze Mrs. Anderson's diet in more detail, you decide, first, to carry out a 24-hour recall since Mrs. Anderson's diet is not diversified. This analysis will be complementary to the dietary history already carried out by Myriam. The second meeting with Mrs. Anderson will take place next week. You are preparing well for this meeting by carefully reviewing the concepts surrounding the 24-hour recall method and by making sure you will bring different tools (food models, measuring cups, measuring spoons etc) that you need in order to help Mrs. Anderson to estimate the portion sizes of food she consumed.

Questions 1: What would be your concrete suggestions so that Mrs. Anderson can easily integrate your advice that will allow her to improve four (4) aspects of her diet/lifestyle. You must consider her health status, life cycle stage, and factors that influence her eating behaviour (psychosocial, economic, cultural context, etc.).

Q2: Include at the end of this section your thoughts on the benefits and limitations of analyzing the nutritional quality of a diet using a 24 hour recall.

Describe an ecosystem that you are familiar with. Include examples of abiotic and biotic factors, producers, consumers, and decomposers. Describe at least two ways that humans have impacted this ecosystem, or similar ecosystems. What is the effect on biodiversity?

A sky diver of mass 53 kg can slow herself to a constant speed of 92 km/h by orienting her body horizontally, looking straight down with arms and legs extended. In this position, she presents the maximum cross-sectional area and thus maximizes the air-drag force on her.

1) a) What is the magnitude of the drag force on the sky diver?

b) If the drag force is equal to bv², what is the value of b?

c) At some instant she quickly flips into a "knife" position, orienting her body vertically with her arms straight down. Suppose this reduces the value of b to 50 percent of the value in Parts (a) and (b). What is her acceleration at the instant she achieves the "knife" position?
