What are the classifications of pesticides according to their general use?

Animals are placed in taxonomic classifications.?

• Animals are placed in taxonomic classifications based on differences and similarities of their traits. If you know what critical traits to look for, it is possible to separate any animal into a taxonomic category. I have reviewed the attached files and still don't understand how to do this assignment. The Dichotomous Key and i even read the instructions over(and over, and over, and over again) and still don't understand how it works. If someone could please help me out with this it would be greatly appreciated!!! If you need further info please let me know and i will upload it. Thanks. The common categories are Domain, Kingdom, Phylum, Class, Order, Family, Genus and Species (Specific Epithet.) Example: Human Classification Domain: Eukarya Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Primates Family: Hominidae Genus: Homo Species: sapiens Scientific name: Homo sapiens Part 1: The assignment document contains a table with images. The images are examples of nine Animal Phylum: Porifera, Cnidaria, Nematoda, Athropoda, Platyhelminthes, Annelida, Mollusca, Echinodermata, and Chordata. Download U5IP_Table. Next, Download Dichotomous Key Use the Dichotomous Key to determine the taxonomic category (phylum or class as shown on the key) for each animal (picture), and write these categories under the Classification Column on the table. You will also need to list the phylum for each animal picture in column one; and list in column 2 all the steps chosen when using the key to arrive at the classification for each animal. For help on how to use the Dichotomous Key, download and review the document called How to use the Dichotomous Key. Save a copy of the table with your name in the file name. Part 2: Using text Chapters 23 and 24 answer the following questions as it relates to the nine phyla in the assignment table. (Porifera, Cnidaria, Nematoda, Athropoda, Platyhelminthes, Annelida, Mollusca, Echinodermata, and Chordata.) Which phyla lack organs? What type of symmetry do they have? List all of the phyla that show cephalization? Do all organisms on the table have 3 germ layers (endoderm, ectoderm and mesoderm)? If not, which Phyla have fewer than three germ layers? One phylum has more species than all the others. State the name of this phylum and provide several different examples of species found in this phylum. According to chapter 24, fish do not all have the same skeletal structure. Describe the differences among fish from the most primitive to more advanced types. Describe the three types of mammals based on how their young develop.

• Answer:

  It's hard to advise without seeing the pictures and the key, but basically the key should have some key defining characteristics of each phyla, that you should be able to match to the pictures in some way. Then you can assign each example organism to its' correct phyla. e.g.Chordates are named because they have spinal chords, therefore if there's a picture of something with a spinal chord - fish, mammal etc then you put it with the chordates. Some stuff that might help from what I remember off the top of my head: porifera are sponges, arthropods are insects, annelids are generally centipedy looking things, Cnideria are jellyfish, echinodermata inc starfish.,platyhelminthes are worms, Nematodes are special tiny worm-like things but aren't quite worms lol. As for the questions: Which phyla lack organs? What type of symmetry do they have? Sponges, radial List all of the phyla that show cephalization?cnideria, arthropoda, platyhelminthes, nematoda chordata i.e anything with a head or any sort of head/tail differentiation Do all organisms on the table have 3 germ layers (endoderm, ectoderm and mesoderm)? If not, which Phyla have fewer than three germ layers? can't remember but its probably the sponges One phylum has more species than all the others. State the name of this phylum and provide several different examples of species found in this phylum. arthropoda, there are more insects than all the others put together According to chapter 24, fish do not all have the same skeletal structure. Describe the differences among fish from the most primitive to more advanced types. you can have bony fish, eg cod and cartilaginous fish, e.g. sharks, the latter being the more primitive Describe the three types of mammals based on how their young develop. monotremes - egg laying mammals, platypus marsupials - kangeroos placentals - humans and everything else not monotreme or marsupial Sure you can take it from there.
