In the first document that is attached is the case, where there are several questions and all of them must be answered. In the second attached document is the rubric by which you have to be guided. The case study must have all questions answered following all the points of the rubric. I also need to know what was the item that was used

Question1

Which do you think has more influence on a person’s weight: genetics, upbringing, or the environment? Why do you think this is so? Is a person’s weight a single genetic trait, a qualitative trait, or a quantitative trait? Discuss and support your response with examples.

Question 2

Describe the difference between artificial selection of organisms and genetically modifying organisms. Include examples that support your response.

The general technique for both parts of this lab will be the same, it’s simply a matter of what stays constant and what varies. For part 1 the length of “wire” on the card that is stuck into the magnetic field will remain constant and I go through values of current up to around 5 amps. For part 2 the current remains fixed but I use cards that have different lengths of “wire” to put into the magnetic field.

Consider the following discussions and write a minimum 3 sentence response to each discussion by Wednesday 4/28 at 11:59 P.M.

1. Suppose we wanted to send a satellite to orbit Pluto at 40 AU away from the Sun to measure the parallax of stars…name 3 advantages and 3 disadvantages of measuring parallax near Pluto versus measuring on the Earth’s surface.

2. We have encountered objects that have entered our solar system from other solar systems (‘Oumuamua is the most famous example…feel free to research this object if you have never heard of it before). What if our solar system encountered another star system today…what would happen to the Sun in that scenario? Would the Earth survive such an encounter? Why or why not?

3. What if the Sun had been born in a tertiary (3 star) system…do you think the Sun would have evolved to be a G star like it is now or would the Sun have evolved into a different type of star? How would planets form in such a system? Where would the habitable zone be located approximately (or would there be one)?

Feel free to use your Chapter 11 Canvas notes to help you with this exercise…also feel free to email me if you have questions or issues with the assignment. The Main Sequence Ranking Task exercise is a fillable pdf document so you can put your answers in the document and submit it to Canvas by Thursday at 11:59 P.M. (note: no late papers will be accepted).

Questions:

1.How is this count selective for yeast and molds?

2.Were the organisms on your plates distinct and separate or were they spreading?

3.What can be added to the media to reduce the amount of spreading colonies?

4.What added media are used to recover molds from food with reduced a_w? Why is this done?

5. Give an example of types of food that is normally spoiled by yeast,fungi or bacteri.

6. List the three groups that fungi can be divided into.

7. Explain three important uses of fungi.

Explore the data.

I want you to load the data, look through it, and then, make it tell a story! To do this, I want you to

1. Really dig into what is there with all of the tools we have at our disposal.
2. Sit down and write out what kind of story you want to tell. What do you want to learn from this data? Write out a paragraph. Or two!
3. Sketch out any data visualizations you might want to make. With pencil and paper – just a theoretical example of what it might look like.
4. Start a fresh .R file and, in comments, sketch out the steps you will take and what you will do.
   4a. Note, for all data viz, don’t just use defaults. Get creative. Make this look like something that we wouldn’t be surprised to find in a magazine or newspaper. Feel free to use alternate themes – even from ggthemes or other places. Google around.
5. Once finished, move the code into a .Rmd file to create a nice, clean, HTMl file that tells a story. Show how you processed the data. and make the visuzliations.
6. If you are a superstar, create a second story! Or dig into a different package – see https://mine-cetinkaya-rundel.github.io/covid19-r/ for a partial list or google around – and see if it can be used to tell a different story.
