Everything Life Sciences Grade 10

1. Science journals such as ”New Scientist”, ”Scientific American” and any other journals
   you can find.


2. Use the Internet widely including the websites below:
   
   
   • Howard Hughes Medical Institute: contains links for educators and learners on
     a variety of approaches to determining causes and potential cures for cancer:
     http://www.hhmi.org/
   
   
   • Whitehead Institute for cancer research. This is one of the world’s leading cancer
     research labs where you can find interactive videos, links to other resources and
     information about a variety of cancers:http://wi.mit.edu/
   
   
   
   

Instructions

Using the resources available, you are required to research ONE of the cancers affecting

humans. In particular you are required to:

• Write a report under the following main headings:
  
  
  • Discuss the major causes of the cancer: discuss cancer with respect to its genetic
    and/or environmental causes and how the cancer spreads within a particular in-
    dividual.
  
  
  • Describe the common beliefs and attitudes concerning the particular cancer
    you have chosen to research: present the popular (common) attitudes people
    have about cancer, its treatment and how cancer is caused in the first place.
  
  
  • Describe the major forms of treatment available: what are the major treatments
    available. Provide an analysis of these under the sub-headings ”Modern biotech-
    nological methods” and ”Traditional methods”.
  
  
  • Describe the prevalence of the cancer type: prevalence refers to how common
    a cancer is in a particular location. Provide statistics in the form of histograms
    and pie charts of how prevalent the cancer is in different age groups, races and
    genders.
  
  
  
  


• At the end of your report, provide a complete list of references of websites, articles and
  other sources of information used in compiling the report.


• Include any pictures, diagrams and information that you think may be relevant to your
  report.

4.5 Summary DUMMY

Mitosis and the cell cycle

• During interphase the DNA replicates.


• The process of mitosis occurs in four stages: prophase, metaphase; anaphase and
  telophase.


• Cytokinesis differs in plant and animal cells. In animal cells the cytoplasm invaginates
  and divides the cell in two, and in a plant cell the cell is divided in two by the cell
  plate which forms the cell wall.


• Mitosis ensures growth of tissues and organisms.


• Damaged and worn out tissues are repaired and replaced by new cells through mitosis.
