Can a cell really go through meiosis II without first going through meiosis I (Module 7, Test Question 9)? Can beet seeds be used rather than radish seeds in Experiment 8.3? For Experiment 6.2, what can I use instead of Anacharis leaves? Has microevolution actually been observed? How are multiple seeds formed within a fruit? Are there multiple carpels in a plant or multiple ovules in each carpel? How many ATPs are made in aerobic respiration? If pollen can land anywhere, why doesn't the pollen of one species of plant fertilize the ovule of another species of plant, making some kind of cross between the plants? If sensing and responding to change is one of the criteria for life, does a one-celled human meet that criterion? In Biology, you say that scientists will never discover the secret ingredient of life. What about cloning? In Experiment 6.2, why did the banana not turn blue when iodine was put on it? In Experiment 7.1, can clear liquid hand soap be used instead of clear dish soap? In Experiment 7.1, is there anything I can use instead of meat tenderizer? In Module 2, does the student need to memorize the bacteria classification scheme? In Module 8, Study Guide Question 12, wouldn't the answer be a “change in chromosomal structure,” and not “change in chromosomal number”? Is it possible to have an allele that is not completely dominant (Biology, Module 8)? Is septate (or non-septate) hyphae an answer to Module 4 Test, Question #5? Mules are infertile and thus cannot produce offspring. Since one criterion for life is the ability to reproduce, is a mule not alive? On Biology Module 7, Study Guide Question 16, why is the answer 8 instead of 16? Since viruses have RNA or DNA, aren't they alive? What are we supposed to see in the plasmolysis experiment (Experiment 6.2)? What does the rubbing alcohol do in the DNA extraction experiment (Experiment 7.1)? What if my results in Experiment 10.1 are not those discussed in the book? What is an isotonic solution? What kind of peas are needed for Experiment 7.1? What kinds of labs are in Biology? How many labs are there? What should I do if I am having trouble seeing DNA in Biology Experiment 7.1? When ATP is broken apart there is a release of energy, ADP, and a phosphate. But the cell takes that ADP and the phosphate and puts them back together to make ATP. Where did the energy to do this come from? Where can I find pond water if the pond is frozen or I live in a desert? I need it for Experiments 2.1, 2.2, and 3.1. Why are secretion vesicles not a valid answer to Module 6, Test Question 5? Why can't I see any organisms in Experiment 3.1?
