Introduction

 

In order for organisms to grow, repair, maintain, and reproduce, cells undergo cell division. Sometimes, cells uncontrollably divide, resulting in cancer. In the first part of the Cancer and Cell Division Lab, you will learn about normal cell division and will compare it to cell division that occurs in cancer cells. You will then visit a website to find out more information about cancer. You will learn why it occurs, why it kills, and new treatments that are being tested and used to treat cancer.

 

Objectives

 

Explain the process of cancer, the effects on the human body, the various types, and the risk factors involved.

Explain various treatments for cancer.

Explain the various stages of mitosis.

Materials

 

No extra materials will be required to complete this lab other than internet service.

Follow the steps under the PROCEDURE section.

Type all answers directly on the data sheet.

Select Save As, and save this document using your last name and student ID as the file name.

Upload the data sheet as a .doc, .docx, or .rtf file when you are finished.

 

While viewing the video, answer the following questions. Total: 8 points

 

1.In which stage of cell division is the DNA copied? (4 points)

 

2.During which stage of mitosis do the chromosomes line up in the middle? (4 points)

 

 

After viewing the video, click on the Information tab in the bottom right corner. Answer the following questions. Total: 12 points

 

1.In which of the cancer types listed, are males not at risk of developing? (4 points)

 

 

2. Cigarette smoke is a major risk factor for which type of cancer listed? (4 points)

 

 

3 The risk for which type of cancer increases after the age of 55? (4 points)

 

Continue following the directions under the PROCEDURE section, and complete the following table. Total: 40 points

 

 

 

  Interphase Prophase Metaphase Anaphase Telophase %of Cell Dividing %of Cells at rest
Normal Lungs              
Cancerous Lungs              
Normal Stomach              
Cancerous Stomach              
Normal Ovary              
Cancerous Ovary              
               

 

 

 

 

 

 

Continue following the directions under the PROCEDURES section and answer the following questions. Total: 12 points

 

1.Based on your data and observations, what are some of the differences between normal cells and cancer cells? (4 points)

 

2.Which type of cancer shows the most aggressive growth? Explain your answer. (4 points)

 

When studying cell division in tissue samples, scientists often calculate a mitotic index, which is the ratio of dividing cells to the total number of cells in the sample. Scientists often calculate the mitotic index to compare the growth rates of different types of tissue.

3.Which type of tissue would have a higher mitotic index, normal tissue or cancerous tissue? Explain. (4 points)

/in /by

To prepare for this article, in paragraph format (one paragraph should be plenty):

  1. Define “invasive species” using the U.S. Department of Agriculture (USDA) website: National Invasive Species Information Center. USDA. https://www.invasivespeciesinfo.gov/unitedstates/state.shtml
  2. Provide three examples of invasive species in your region.
  3. Define “endemic species,” and provide an example of an endemic species from anywhere in the world. If you can find an example of an endemic species in your region, please include it as well.

Now read the article Political Responses: Where eagles dare. (2013, Sep 14). The Economist, 408(8853):9. Accessed at http://www.economist.com/news/special-report/21585083-more-prosperous-countries-now-favour-protecting-wildlife-not-killing-it-where-eagles on August 16, 2016.

After you have read the article, answer the following questions in paragraph format by using an introduction sentence, related topic sentences, and a conclusion statement that draws connections between the ideas presented. You should be able to address all questions in Part I in 1–2 paragraphs.

  1. Name some ways that governments are trying to redress threats against endemic species. Briefly describe the examples presented in this article.
  2. What is described as the biggest challenge for governments?
  3. How are governments addressing this challenge?

Part II

With habitat loss, less land and resources means lower carrying capacity. For the second part of this assignment, you will apply the readings from your Module 4 Home page to two cases in which conservation of habitat applies to carrying capacity and economics. Choose one of these large predators to investigate: African predators (lions, hyenas, etc.), cougars (mountain lions), or polar bears.

  1. What size of land/water is required to support this animal?
  2. What pressures threaten this organism’s habitat?
  3. What role does international trade and political regulation play in protecting this organism? Are these in place and enforced?

Part III

Finally, examine the costs and benefits of conservation using the Montgomery Botanical Centre as a case study. View the results of a study on the costs and benefits of preserving a collection of plants at the following site: http://www.bgci.org/resources/article/0634/.

In 1–2 paragraphs summarize the following, using complete sentences:

  1. What are the costs associated with maintaining this collection (generally speaking, not exact numbers)?
  2. What are the benefits of preserving this collection and how are they measured? (Hint: They are described as “conservation success.”)
  3. What part of this collection gives diminishing returns and why?
  4. How does collection size relate to efficiency of management of the collection?
  5. When is it most valuable to preserve a plant species?
