1. Why is it better to have only 2 choices at each step instead of more? It narrows your options down. 2. What problems did you encounter in using the dichotomous key? Be specific and discuss fully. We thought it was more than one characteristic that fit more than one candy. 3. How did you resolve your problems in #2? Did all the other ones and came back to it. 4. Do classification keys go from general to specific characteristics or from specific to general characteristics? Explain why. They go from general to specific characteristics. 5. What does the first and second part of the Latin name represent in the scientific name of the organism? A fromal name according to an internationally accepted standard, especially the formal name of a taxon. 6. Research Carolus Linnaeus and his contribution to modern classification. Carolus Linnaeus laid the foundations for the modern scheme of binomial nomenclature. He was known as the father of moder taxonomy and Is also considered one of the fathers of ecology. 7. What is a dichotomous key? (define) A dichotomous key is usually a written device constructed from a series of highly organized statements arranged into couplets. 8. What is binomial nomenclature? (define) A binomial nomenclature is the system of naming organisms. 9. Briefly describe how classification has changed before and after Linnaeus. Research Aristotle... They follow a stricter scale. 10. List the order of classification groups from Kingdom down to species. Kingdom, phylum/division, class, order, family, genus, species. = Seed Lab: =
 * Candy lab questions to answer:**

Our Labeled Squash plant.

Our labeled AlfAlfa seed.

Garrett Hoffman, Brook Grove, Taylor Clark, Morgan Lantz **1. What are the changes that you observed throughout the experiment?** Kirsten got really tired and went slower during her work out.

All of those changes can help the body maintain equilibrium because it will raise the rates of things and has to restore itself after the physical activity is over.
 * 2. How do each of those changes help the body adjust to maintain equilibrium (homeostasis)? **

Some of the mechanisms used to maintain body temperature in the body are the amount of oxygen the body receives.
 * 3. What mechanisms are used to maintain body temperature in the body? **

The purpose of increased respiratory rate and heart rate is to get the body more oxygen and get it flowing through the body faster.
 * 4. What is the purpose for an increased respiratory rate and heart rate? **

As we did the exercises we found out that bodily changes started to occur. For example, her starting pulse was 113, her blood pressure was 98 over 82, and her body temperature was 32 degrees Celsius. After recording that she skipped/ ran around for 5 minutes and jumped rope for 3 minutes. Her face started to turn red, and her breathing started to increase. Then we recorded her pulse which was 135, her blood pressure was 119 over 88, and her temperature was 38 degrees Celsius. She did five more minutes of running/ jumping rope and started to sweat and her breathing was horrible. We recorded her blood pressure again and got 107 over 78, with a pulse of 119 and a temperature of 38 degrees Celsius. Overall we figured out that the more physical activity that she did, it began to take more of an effect on her body.
 * 5. Write a paragraph about the conclusions you can draw about your body's ability to maintain equilibrium (homeostasis.) Be sure to discuss some of the information from your other answers. **


 * || ** Blood pressure ** || ** Pulse ** || ** Temperature ** ||
 * ** Before Exercise ** || 98 over 82 || 113 || 32 degrees Celsius ||
 * ** In Between Exercise ** || 199 over 88 || 135 || 38 degrees Celsius ||
 * ** After Exercise ** || 107 over 78 || 119 || 38 degrees Celsius ||

Some of the procedures that could be measured in the experiment would be skin color, heart rate, and perspiration, breathing rate, blood pressure, and body temperature. Our Exercise was to skip continuously for five minutes and go directly into jumping jacks for three minutes.

1. Heterotroph 2. in the same class as jellyfish & seahorses; they attach themselves to sea animals; they feed on small plankton. 3. http://www.encyclopedia.com/topic/hydra.aspx

1. Euglena are heterotrophs 2. it maintains its shape by cell structures; they have little things attached to their heads that look like and work like propellers 3. http://www.buzzle.com/articles/euglena-facts.html
