Midterm Question 1
Has two choices, choose only 1! Use only APA. DO NOT USE the INTERNET I WILL KNOW!!! You have a plagiarism check for all your submissions.

You may use your textbook and any resources that I have provided. Do not copy and use as your own words, I will know. Do not copy from each other. Use only APA citation style.

1. Lisa Simpson from The Simpsons” is working on a science project. Her task is to answer the question: “Does Rogooti (which is a commercial hair product) affect the speed of hair growth.” Her family is willing to volunteer for the experiment. 350 pts.

You are her science partner. You volunteer to design the entire experiment.

Using what you learn to make sure you follow the Scientific Method, design the experiment. You may make up data to show how you would collect and record. You can also do the calculations. But it must be a complete designed experiment based on the given information lecture and any resources. As a thank-you, she sent her picture!!!

Or you can choose

Midterm Question. 1A There are five brief questions, but if there are not correct and substantive in content-knowledge, you could lose the points. See below:

Part of the above: Answer the parts first three questions with correct substantive content.

1a. What are the structural and physiological differences between these two cells  ?

2b. i. What are enzymes?

ii. Explain how enzymes are involved in transporting molecules in the body?

iii. Carbonic anhydrase is an enzyme involved in the reaction of carbon dioxide with water to form a molecule that dissolves well in the liquid part of blood. How does carbonic anhydrase affect this reaction?

3c. Give an example of homeostasis. Explain why your example is a good definition.

Extra-toed Cat Toes: Is it a benefit or a detriment mutation?

/in /by

Mid-term Question 2

The outcome of a genetic mutation most often is harmful, but some mutations can be beneficial. Did you know that most cats have five toes on their front paw?

But there is a mutation found in cats where they have seven toes on the front paw.

These extra toes are on the thumb side of the paw. Now I know that you did not study the genetics of cats so you may use Google for seven-toed cats to help you.

Here are two sites that you may use:

Her is some information that you may need as well as the concepts in your Textbook. Remember I have the hyperlinked pdf in the course content.
You may not use Wikipedia or any sites other than the two I provided.
Extra-toed Cat Toes: Is it a benefit or a detriment mutation? The affected protein in extra-toed cats is sonic hedgehog (SHH). SHH is a signaling protein normally made by cells on just the pinky side of the developing foot. As the toes form, their number and identity depend on their exposure to SHH protein. Cells exposed to the most SHH become the pinkie toe. Cells exposed to intermediate levels of SHH become ring or middle toes. And cells with the least exposure to SHH become the index toe. IS there a selective advantage to this variation for the cat?( incorporate in your essay)
Genes can jump around and even translocate to other chromosomes. Identify the famous geneticist who discovered the jumping gene(incorporate in your essay) A single-base change outside the protein-coding sequence of the Shh gene makes a new switch. This switch turns on the Shh gene on the other side of the foot.
Directions Read and think and follow.
In an explanatory essay, explain why this is an unusual inheritance pattern. Incorporate in your answers, the questions below and any boldfaced questions in the above paragraph, but do not respond to them separately. Incorporate the responses in an organized approach.
Is it a variation or a disease?
Is it harmful or beneficial?
Could this odd mutation happen in other animals?
Identify the mutation pattern.
Here are some questions to help guide your

Cultural encounters can prove to be very enriching to all those involved

/in /by
The student’s work should be presented in an ESSAY of around 500 words.
Referencing:
The essay should include a list of references (print and electronic) at the end in addition to in-text referencing as per the requirements of the Harvard Referencing System. Proper referencing is a serious academic requirement and skill and will be rewarded accordingly.
Writing and Discussion Topic:
Cultural encounters can prove to be very enriching to all those involved, yet could prove very confusing and disrupting. In most cases these encounters lead to a conflict of values, both at the individual and societal levels. Explore how cultural encounters are manifested in literary works, specifically short stories from An Anthology of Short Stories from Five Continents, with particular reference to “The Distant Past” by William Trevor.
In the process of answering the TMA, you should make sure to include the below five sub questions:
1)  How is the concept of cultural encounter treated in the short story “The Distant Past”?
2) Is the author, William Trevor, aware of the cultural encounter theme? How does he manifest that awareness?
3) Are the main characters, mainly the Middletons, aware of the cultural encounter theme? What clues do they provide of such awareness?
4) How does the Friday visit to town highlight the theme of cultural encounter in “The Distant Past”?
5) How does the usage of “contrasts” (present versus past, now versus then) throughout the short story help in highlighting the theme of cultural encounter?
Guidance on Addressing the Topic:
Before you embark on writing the essay, you need to read carefully Book 3 Cultural Encounters in order to familiarize yourself with the topic at large and make use of the skills presented in the book when writing your essay. You are strongly advised to consult sources on the topic and widen your knowledge of the topic under consideration, but it is of the utmost importance to document any words or ideas that are not your own. Once you have the material ready, it is advisable that you follow the steps (1-5) indicated in the section above to avoid omitting sub-questions. Although the topic is most relevant to Unit 3, you should demonstrate your knowledge of the complexity of the concept of cultural encounters as presented in the all the units to draw lessons and examples from them if need be, and not model your treatment solely after a particular treatment appearing in a single unit.
