Biology 11 1-1 and 1-3, 7 Oct 2016

Please ensure that you are able to answer all the questions from today’s case study on viruses/bacteriophages:

  1. What are some of the differences between a bacteriophage and a bacterium?
  2. Why do most viruses that infect bacteria have tails, whereas most viruses that infect animals and plants do not?
  3. What is the “life” cycle of a T-even bacteriophage?
  4. What is the function of a virion?
  5. Describe the structure of a T-even bacteriophage.
  6. Could bacteriophage be used to combat bacterial diseases?
  7. What type of energy is required for new bacteriophages to be assembled?
  8. How many tailed bacteriophages are there, and where are they located?
  9. Why are viruses not classified as living? 1
  10. Are bacteriophages harmful to people?

Biology 11 2-3 4 October 2016

In groups of 2 or 3, answer the following questions:

  1. List the shapes of bacterial cells and provide a diagram.
  2. List the arrangements of bacterial cells and provide a diagram.
  3. What other characteristics of bacteria are used to identify them?

Essential questions we are considering at this time:

  1. what are the characteristics of prokaryotic and eukaryotic cells?
  2. how did eukaryotic cells evolve?

Mini Science 10 2-4 4 October 2016

List the combining capacities and number of valence electrons for the groups/families shown on the blank periodic table handout.  Notice the pattern and the relationship between the valence electrons and combining capacity. Be sure you have read about Lewis dot structures and the rest of 4.1 in the text.

Biology 11 1-1 and 1-3 3 October 2016

Bacterial disease research – For your assigned bacterial disease, research:

  1. bacterial that causes the disease
  2. transmission of the disease (how it is caught or passed between people, how it spreads)
  3. symptoms of the disease
  4. treatment
  5. include a diagram of the bacteria (type, arrangement, other identifying features; eg. are they gram positive or gram negative) or other important features of the illness
  6. include references on back of poster
  7. poster should be colourful, visually appealing, neat, include labelled diagram(s) and point form information

You will have 20 minutes at the start of next period for any last minute poster preparations, then you will be called upon to give a brief (1 minute) presentation on the bacterial disease.
