1. Think about what you know about insects. Are insects arthropods? Explain why or why not. Please use specific examples of different arthropod characteristics to support your answer. Yes, Insects are Arthropods. They have a dorsal heart and a ventral nervous system. All arthropods are covered by a hard exoskeleton made of chitin. Sometimes it sheds its skin when it molts.

2. In the class lecture, it was said that Isopods are dorsoventrally compressed. What in the world does that mean? What are other things in nature that can be described as dorsoventrally compressed? Explain. Dorsoventrally compressed means that the body is flattened. Examples: pill bugs or sow bugs.

3. Do you eat anything that Isopods eat? What "foods" do you have in common with Isopods? What "foods" do you not have in common with Isopods? Elaborate please. Yes I eat fish, and sushi. Some other things that isopods eat that I don’t eat are wood.

4. Many female scorpions will carry their young on their back to protect them until the young are more able to protect them selves. What would life be like if human mothers and fathers carried all of their young around on their backs? How is this similar to what humans already do and how is it different? I think life would be completely different. I say that because it wouldn’t be as much trouble to get into, a mother would now where her child is. Most teens would have a job like they do now because after our parents leave their job they would have to " carry" us to our job. I don’t think it would be as many teenage mothers either.

5. Cathedral Termites build quite interesting homes for themselves. Pretend that you lived in a Cathedral Termite mound. What are the advantages and disadvantages of life in the mound? An advantage would be they use grass to keep cool, Some disadvantages would be that they use their "poop" because its like glue, (so imagine walking round an cathedral’s mound) and if it rained it would destroy their mound. Predators might come and destroy their mounds aswell and eat them also.

6. The Huntsman spider lives in Australia. Although it is quite large, the spider’s bite is essentially harmless. If this is true, how does the Huntsman spider cause harm to humans? Would the Huntsman spider affect you in the same way? It causes so much harm to people because, it scares people. Yes, it would affect me in the same way, because I am afraid of spiders and any other insects.

Meisha - your answers to numbers 1, 4, and 5 are outstanding!! You really thought about your answers and demonstrate that you really understand the material. My concern with numbers 2, 3, and 6 is really the length of your answers. All of your answers are correct, but they should be written as paragraphs. I want you to expand more on these answers. I know you know the material, so this should be really easy to fix. Please go back and add more to questions 2, 3, and 6. If you do this, you should have an A on this assignment easily.
