study questions
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.
insects are arthropods because the they have segmented bodies and most of them are symmetrical just as it lists under the catagory of an arthropod.
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. it means that they are flat on the top side some examples are a sting ray, a star fish, and a centipede.
3. Do you eat anything that Isopods eat? What “foods” do you have in common with Isopods? What “foods” do not have in common with Isopods? Elaborate please. isopods eat potatoes, leaves and twigs and also they may eat newspaper and paper towels. we as humans eat potatoes so thats one similar thing that we have in common. isopods eat grass, leaves and other plants and as humans we eat plants also as cabbage, collard greens, and other various vegetables which are also known as plants.
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? if mothers and fathers carried their young on there backs it probably wouldnt be a good idea because the parents would hardly be able to get any work done. what scorpions do are similar to what humans do, scorpions carry their young on there backs until they are able to take care of themselves. humans nuture and take care of their babies for a long time, up until the age of 18.
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? the advantage of the mound is that it keeps the termites out the the hot blazzing sun. the disadvantage is that the termites make their houses out of poop and wastes that other animals and insects leave on the groung and i wouldnt want to live in anything like that.
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? i think it would effect us the same way. it might not kill us as it would do another insect but it would cause pain and the bite could turn out to be deadly. the huntsman spider causes harm to humans by scaring them while they are are driving because they are found mostly in cars.
