Scientific Investigation

  • see below

 

  • note that you are responsible for answering any and all prompts and questions within the lab topic, not just those questions found at its end
  • if we don't end up actually doing the step-test experiment, then you will not be held responsible for completing those parts of the lab topic that require our performing that experiment

Microscopes and Cells

  • see below

 

  • students: bring in a sample of pond water for this exercise, weather allowing, as directed in your text (the more organics in the water the better)
  • use figures from your lecture text to fill in table 3.1 (p. 72)
  • we will not be doing exercise 3.4.2 (p. 70)
  • you may pair up to dissect the termite (3.5.A.2 - pp. 73-74)
  • in exercise 3.5, lab study B we will be using depression slides, not broken-glass chips
  • we will do exercise 3.5, lab study D (pp. 77-79) only if we (that is, one of us, not necessarily you) have a reasonably good pond-water sample
  • answer all questions except #s 1, 2, and 4b on page 78 and #s 1 and 3 on page 79
  • Laboratory Instructor: Bring over a microscope or two from the microbiology lab

Vertebrate Anatomy I: The Skin and Digestive System

  • see below

 

  • please, except in the case of allergies, you should dissect at least one pig (that would be one pig per person, though you may still work in pairs, so long as you still conscientiously dissect your own pig)
  • those of you who are really into animal anatomy, e.g., those interested in animal science, veterinary science, or medical science, please dissect as many pigs as you wish, so long as you aren't doing so simply for the sake of being wasteful
  • answer all questions, except #s 2 and 3 in the Applying Your Knowledge section on pages 586

 

 

22

Vertebrate Anatomy II: The Circulatory and Respiratory Systems

  • answer all questions

 

 

23

Vertebrate Anatomy III: The Excretory, Reproductive, and Nervous Systems

  • answer all questions, except # 3 in the Applying Your Knowledge section on pages 632

21,22,23

see lab 2 above

  • Let's try to finish these labs, 21-23, today
  • Laboratory Prep-person: Exercise 7.5 (pp. 175-178) must be started 10-12 days prior to the beginning of the laboratory period scheduled two weeks from today

Mitosis and Meiosis

  • see below

 

  • once you have completed this laboratory topic you should be able to model or sketch mitosis and meiosis from memory, without help, in front of your instructor as well as correctly employ the various associated terms and concepts; in other words, this laboratory period is a really swell time for you to practice your knowledge of mitosis and meiosis
  • if beads strike you as really stupid, then prove to yourself that you can sketch out and label cartoons from Figures 12.6 (pp. 222-223) and 13.86 (pp. 244-245) of your text, plus recite the gist of the captions, from memory!!!!
  • we will not be doing Lab Study A, section 7.3
  • answer all questions, except #s 3 and 6 in the Applying Your Knowledge section on pages 180-183
  • as always, complete any other material found in the text of this lab topic
  • consider taking home pop beads to use to study for the upcoming lecture exam

Lab Exam

  • complete/review lab number 4
  • see "laboratory exams" in your syllabus·  please return any pop beads you have taken home when you are done with them (though note that meiosis will be on the next midterm exam)

Population Genetics: Hardy-Weinberg Theorem

  • see below

 

  • read appendix B
  • much of this experiment should be done in groups (e.g., of 2)
  • we will try to summarize the results of different groups at some point in the period
  • remember that allelic frequencies will always add up to 1
  • start exercise 11.1 with a 50:50 ratio (pp. 274-276)
  • skip doing exercise 11.2, experiment 2 (Founder effect; pp. 283-284) but do try to understand how it differs from experiment 1 (Bottleneck effect)
  • the most important thing to learn from exercise 11.2, experiment C (pp. 285-293) is how to recalculate allelic frequencies following selection
  • Answer all questions (note: this statement may be subject to revision)

Animal Development

  • we won't be doing exercise 24.3 (pp. 650-654) though please read it and observe figure 24.7 (p. 654)
  • answer all questions
  • Comparative embriology link (nice images)
