Be sure you have finished 4.1 and 4.2 in workbook and that you read 5.1 in textbook. Research the questions: “Is there an advantage to sexual reproduction (and the process of meiosis)? If so, what is it? You don’t need to hand in the research but you should jot some notes down so that you can discuss it in class.

Please ensure that you are able to answer all the questions from today’s case study on viruses/bacteriophages:
- What are some of the differences between a bacteriophage and a bacterium?
- Why do most viruses that infect bacteria have tails, whereas most viruses that infect animals and plants do not?
- What is the “life” cycle of a T-even bacteriophage?
- What is the function of a virion?
- Describe the structure of a T-even bacteriophage.
- Could bacteriophage be used to combat bacterial diseases?
- What type of energy is required for new bacteriophages to be assembled?
- How many tailed bacteriophages are there, and where are they located?
- Why are viruses not classified as living? 1
- Are bacteriophages harmful to people?

Read section 17-1 (viruses ) and 17-2 (prokaryotes) in textbook.
Biology 11 2-3 4 October 2016
In groups of 2 or 3, answer the following questions:
- List the shapes of bacterial cells and provide a diagram.
- List the arrangements of bacterial cells and provide a diagram.
- What other characteristics of bacteria are used to identify them?
Essential questions we are considering at this time:
- what are the characteristics of prokaryotic and eukaryotic cells?
- how did eukaryotic cells evolve?

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.
