2 BIOLOGY Week of: 10/19-10/23 Ms. Angela Rawal & Ms. Maryam Siddiqui

3 Monday 10/19: Cheek Cell Lab 1. List the 3 parts of the Cell Theory 2. Describe or define each of the following –cell membrane –Cytoplasm –nucleus –organelle 3. Sketch the cell at low and high power. Label the nucleus, cytoplasm, and cell membrane. Draw your cells to scale. 4. Sketch the cell at low and high power. Label the nucleus, cytoplasm, and cell membrane. Draw your cells to scale. Procedure: 1. Put a drop of methylene blue on a slide. 2. Gently scrape the inside of your cheek with the flat side of a toothpick. Scrape lightly. 3. Stir the end of the toothpick in the stain and throw the toothpick away. 4. Place a coverslip onto the slide 5. Use the scanning objective to focus. 6. Switch to low power. 7. Once you think you have located a cell, switch to high power and refocus.

4 Cheek Cell Lab Continued.. Go to: y/ketcham/microscope/ y/ketcham/microscope/ Complete the virtual scope application Answer questions 1-6 for homework Take the Microscope Parts Practice Quiz Online at: om/microquiz/index.html#

5 Tuesday 10/20: Mitosis PART A View the “Animal Cell Mitosis” tutorial and read “Events During Mitosis” at: Answer the corresponding questions under “Mitosis Tutorial” found at: com/worksheets/mitosis.h tml com/worksheets/mitosis.h tml PART B Go to: r.com/flash/mitosis.html r.com/flash/mitosis.html View both the Whitefish and Onion Roots slide tutorials Using these slides, complete the table “Mitosis in Whitefish & Onion Roots” found at: com/worksheets/mitosis.h tml com/worksheets/mitosis.h tml

6 Wednesday 10/21: Genetic Diversity Visit: 2/Furr/GeneticDiversity/GeneticDiversityH ome.htm 2/Furr/GeneticDiversity/GeneticDiversityH ome.htm Read through the tutorial introduction, then click START at the bottom of the page to begin The tutorial will run you through infomation, animations, & questions about –Random assortment –Recombination –Fertilization

8 Life’s Five Kingdom continued. Go to: to learn about different microorganisms.http://library.thinkquest.org/CR /micr.htm Go to: to learn about different bacteria and their taxonomy.http://library.thinkquest.org/CR /hometax.htm Go to: to learn about habitat of bacteria.http://library.thinkquest.org/CR /habit.htm hill.com/sites/ /student_view0/unit4/chapter17/interac tive_tutor.html Do the interactive Tutorialhttp://glencoe.mcgraw- hill.com/sites/ /student_view0/unit4/chapter17/interac tive_tutor.html After going through the above tutorial take the test and submit your answers using LiveText. Test is available at; hill.com/sites/ /student_view0/unit4/chapter17/chapte r_test.html hill.com/sites/ /student_view0/unit4/chapter17/chapte r_test.html

9 Thursday 10/23 Evolution Lab In this lab, you will use a computer simulation to track a population of organisms as they evolve. You will take data on the number and varieties of the organisms and graph them to show change over time and determine how two factors: MUTATION RATE and SELECTION STRENGTH affect how populations evolve Instructions 1. Go to and click on the link that says "evolution lab" 2. Read the introduction and the contents to learn about the imaginary creatures you will be studying and how to operate the simulator. You may also want to look at the help link. 3. Open the simulator and practice using the controls before you go on to the real simulation. Be sure to "reset" the simulator when you're finished practicing.

10 Evolution Lab Continues The Simulations Simulation A – The purpose of this simulation is to determine how the mutation rate affects the evolution of your population. You will need to run 4 trials with varying settings for mutation rate. Fill out the Data Table and create a graph using the graphing program at. You will have 4 lines on your graph. The X-axis will be cycles, and the Y will be mean phenotype. Simulation B - The purpose of this simulation is to determine how selection strength affects the evolution of your population. Run three trials with the selection strength at 0, and three trials with the selection strength at varying ranges. (See data table) Fill out the data table and create a graph for simulation B. com/worksheets/evolution -data.html

11 Evolution Lab Continues Analysis: Answer the following questions on a separate page, title this page "Evolution Simulation" and make sure your name is on it. You can even type it in Word if you like. 1. Describe how the simulation models natural selection (and evolution). 2. Explain HOW the mutation rate affects the evolution of your populations. --> Explain WHY the mutation rate affects the evolution of your populations. 3. Explain HOW altering the selection rate affects the evolution of your populations. (You may want to include an explanation of what "selection strength" means.) --> Explain WHY altering the selection rate affects the evolution of your populations.
