The six characteristics of living things, and an explanation of each one. \nTheme #1 - Cells \n\nAll living things are composed of one or more cells. Different types of cells have different "jobs" within the organism. Each life form begins from one cell, which then will split. These cells split, and so on. After this has happened several times, differentiation is undergone, when the cells change so that they are not the same thing anymore. Then they are used to begin to put together the final organism, some cells, for example, as the eyes, some as the heart, etc. The only arguable exception to this is viruses. They are not composed of cells, but are said to be "living." \nTheme#2 - Organization \n\n \nComplex organization patterns are found in all living organisms. They arrange themselves on very small levels, grouping like things together. On larger levels, they become visible. This also has to do with differentiation, as the cells are organized in a manner that makes sense for the organism after they change to what they’ll be in the final organism. \n\nTheme#3 - Energy Use \n\nAll organisms use energy. The sum of the chemical energy they use is called metabolism. This energy is used to carry out everything they do. Autotrophs (plants) use energy from the sun for photosynthesis, to make their own ‘food’ (glucose). Heterotrophs (animals and humans) must ingest food for this purpose. \n\n\nTheme#4 - Homeostasis \n\nAll organisms have stable internal conditions which must be maintained in order to remain alive. These include temperature, water content, heartbeat, and other such things. In a way, this has to do with energy use, because a certain level of energy must be kept within the body at all times. For this, obviously, humans must then ingest food on a regular basis. Not all conditions are for the body to maintain itself; though most are. \n\n\nTheme#5 - Growth \n\nAll organisms grow and change. Cells divide to form new, identical cells. Differentiation happens, as well, when cells mutate into other types of cells, making a more complex organism. Organisms growing, changing, and becoming more complex is called development. Single-celled organisms do grow as well, but they will only become slightly larger – this is nearly unmeasurable. \n\n\nTheme#6 - Reproduction \n\nAll organisms reproduce in order to continue the species' life. This is combining genetic information (in sexual reproduction) or splitting into two organisms (in asexual reproduction) in order to create another of the same species. In sexual reproduction, the new organism will have some characteristics from the mother, and some from father. It may look like either of them, or it may not. In asexual reproduction, the new organism is an exact copy of the first. Sometimes, not every member of a species is able to reproduce. As long as others are (which we know they can, if they still exist today) then it does not threaten the species. (Except for mules, but don't worry about them, they are a bizarre anomoly.)

All living things have 7 characteristics. They form the acronym GRIMNER.\n1) Growth - permanent increase in size\n2) Reproduction - ability to produce offspring\n3) Irritability - the ability to detect and respond to stimuli (changes\n         in the environment)\n4) Movement - ability to change the position of the whole or part\n         of the body\n5) Nutrition\n6) Excretion - rmoval of metabolic waste\n7) Respiration - ability to release energy from food

What are the major taxonomic categories that we use to organize all life on earth -- species, genus, family, order, phylum, etc?  How many Kingdoms are there and how are they determined?  Give the full taxonomy for Homo Sapiens.\n\nWhat is DNA?  What is RNA?  Describe the steps of RNA transcription.  What is mitosis?  Decribe the steps of mitosis.  How is this different from mieosis?\n\nWhat is a gene?  What is the difference between phenotype and genotype?  What is a dominant gene?  What is a recessive gene?  Why is a dominant gene dominant?  What are the other kinds of gene relationships (co-dominance, etc.)  \n\nDescribe the Theory of Evolution.  What was the evidence Darwin found to come up with the Theory.  How do species evolve over time?  What is speciation and give three examples of how different species can evolve?  What is mutation?  What other times of gene changes are there that are related to evolutionary development?\n\nWhat is an ecology? What are the various types of relationships between species (predation, parasitism, mutualism, commensalism, etc.) and give examples of each. What sort of defenses do species develop against predation?  What sort of features do predators develop in return?\n\nWhat is reproduction?  What are the different kinds of reproduction?  How does reproduction differ between various plant species?  Between animal species?  What are some examples of (I forget the term but) animal features/behaviors that serve only to help with reproduction?  How do these evolve?\n\nWhat is a bacteria?  What is a virus?  What are the differences between prokaryotes and eukaryotes?  What are the major organs in a prokaryotic cell/organism?  How about a eukaryotic cell/organism?  What do each of these do?  What is the current theory on how mitochondria evolved?  What is special about the cell wall and how does it allow material to get across it?  What about the cell nucleus?\n\nWhat is involved in genetic science?  What sorts of things can genetic science do and what are the tools?  What is gene splicing?  What is genotyping and genetic sequencing?  How do these work?\n\nDescribe the major organs and organ systems in the human body.  What is the function of each?  What is the structure of each.  What are some examples of tissue types and how do you recognize them under a microscope?  What are some of the major diseases that humans suffer and what are the symptoms and cures for each?  How is food processed by the digestive system and which food elements are digested in which organs?  What are the more important hormones and neurotransimitters in the human body and what does each do?  \n\nDescribe the different groups of organic molecules important to life -- proteins, carbohydrates, lipids, etc.  What is the molecular structure of each and how are they different?  What is the importance of each and what is their function in the human body?  What is an amino acid?  How many are there, and what do they do?\n\nAnd so much more ... sheesh.

Objective:\nStudents will use a key to determine the phyla of invertebrates.\nMaterials:\n· keys\n· pictures of invertebrate organisms\n· definition of terminology\nProcedures:\n1. Teacher puts a letter on back of each picture.\n2. Students are broken into groups.\n3. Each group gets a stack of pictures and uses the key to determine which phyla the animals belong to.\n4. Students can use the definition sheet to help them with the key.\n5. Teacher reviews the correct answers to the pictures.\nDiscussion:\nA. Was the key helpful in identifying the invertebrates? Why?\nB. Write the characteristics of each animal pictured, its phylum, and common name.\nC. Would you change the identification key? How?\nActivity #1 - Using a Dichotomous Key for Invertebrate Phyla\nTaxonomic Key to the Major Invertebrate Phyla\nMost taxonomic keys are “dichotomous,” (two branches), which is to say they are written with a series of\ntwo choices to be made about the anatomy of an animal (or photograph of an animal) you are looking at.\nKeys are not made to be read from start to finish like a book or a poem. In each numbered series you should\nread both choices, determine which choice best applies to the specimen you are looking at, then go where\nthe key tells you to go, often skipping other steps in between that don’t apply.\n1. Radial symmetry or asymmetry…………………………………………….……………2\nBilateral symmetry………………………………………….……………………………4\n2.

Here is a great website for that sort of research. It has a taxonomic chart with hyperlinks to information, pictures, sounds, and specimens. There are more than a dozen phylums of 'worms' represented with many photos to help with identification. \n\nhttp://animaldiversity.ummz.umich.edu/site/accounts/classification/Animalia.html

This doesn't really belong in Earth Sciences.  Biology or Botany are more specific categories for questions about living matter.  However, I'm in a good mood because it's Friday.  Check the link.
