Insect Classifying Arthropods Virtual
Introduction to Biology chance upon Julie Maxwell Classifying Arthropods Virtual lab (Week 8) Go to the following website for completion http//www. mhhe. com/biosci/genbio/virtual_labs/BL_18/BL_18. html Upon completion of the Classifying Arthropods Virtual Lab, enjoy answer the following questions thoroughly using complete sentences and proper grammar and spelling. information Table Body Sections(1,2,3, or & ampgt3) Walking Legs (6,8 or &gt8) Other Appendages Antennae(0,2 or 4) Claws Present? Jaws Present? Class Common Name specimen 1 Specimen 2 Specimen 3 Specimen 4 Beach Hopper Questions 1. Many species of arachnids argon predators, but stick no teeth or jaws. How do they obtain nutrients from their prey? They germinate venom in the prey that paralyzes them then the predators suck out the nutrients they need. 2. Arthropods are the most diverse group of animals. Describe almost characteristics of arthropods that may guide contributed to t heir great evolutionary success.The body segment, the segments usually grouped in both or three rather distinct regions making them highly mobile. * mated segmented appendages (from which the phylum gets its name) making them ambulate &amp walk easily. * zygomorphic symmetry making them relate to the environment quite easily. * A chitinous exoskeleton, which is periodically shed and renewed as the animal grows making them resistive to shock of hard objects. * A tubular alimentary canal, with mouth and anus method of accounting for good food digestion. The circulatory system an open one, the only telephone circuit vessel usually being a tubular structure abaxial to the alimentary canal with lateral openings in the abdominal region ensures go perfusion and less chances of hemolysis due to their being highly mobile. 3. What are some advantages and disadvantages of having an exoskeleton? Advantages are, the exoskeleton provides a bony plate of armor for support and prote ction of the quiet internal tissues and organs. Disadvantages it limits the possible size of the animal.Since the weight of an animal is a take to the woods of its volume, a doubling of an animals size increases its weight by a factor of 8. 4. Which of the five classes of arthropods is the most diverse? Explain. Insecta or Hexopoda ( insects) is the most diverse class. There are about 900,000 known insect species, three times as many as all opposite animal species together, and thousands of new ones are described each year. They are unremarkably grouped in 27 to 32 orders, depending upon the classification used. The largest order is that of the beetles (Coleoptera).Next, in order of size, are the moths and butterflies (Lepidoptera) the wasps , ants , and bees (Hymenoptera) and the flies and mosquitoes (Diptera). Other major orders are the rightful(a) bugs (Hemiptera) the cicadas , aphids , and scale insects (Homoptera) the grasshoppers and crickets (Orthoptera) the cockroaches (Blattodea) and the mantids (Mantodea). 5. For each of the following characteristics, indicate whether the trait is common to Phylum phylum Arthropoda or specific to certain classes of arthropods wings, chewing mouthparts, jointed appendages, number of legs, segmented bodies, type of respiratory structure, exoskeleton.
