Changing earth
All of the vocab , fossil types and facts.
| Term | Definition |
|---|---|
| mold-fossil | when an organism is buried beneath the ground and the flesh and bones decay/deteriorate leaving it a cavity. |
| cast fossil | |
| carbon film | |
| trace fossil | |
| preserved remains | |
| Catastrophism | idea that conditions and organisms on Earth change in quick , violent events. |
| Uniformitarianism | states that geologic processes that occur today are similar to those that have occurred in the past |
| stratigraphy | the branch of geology that studies the order and relative age of rock/soil layers on Earth. |
| law of superposition | states that the youngest layers of Earth are located on the surface and as you go deeper into the Earth, the layers get older. |
| relative age | a comparison to find the age of something rather than actual numbers. |
| index fossil | fossil of an organism that was alive for only a short period of time, were abundant and widespread geographically; scientists can use these to assign dates to rock layers |
| absolute age | the actual age in numbers |
| radiometric age | the process of finding absolute age by breaking down isotopes into other isotopes and particles. |
| halflife | time the isotopes take to decay. |
| Variation | is a slight difference in an inherited trait of individual members of a species |
| Mutations | are random genetic changes that result in new variations |
| Natural Selection | the process by which populations of organisms with variations that help them survive, live longer, compete better and reproduce more than those that do not have those variations. |
| Adaptation | an inherited trait that increases an organism’s chance of surviving and reproducing in its environment |
| Camouflage | an adaptation that enables a species to blend in with its environment |
| Mimicry | an adaptation that imitates the appearance of another species |
| taxonomy | the classification and organization of something, especially organisms. |
| linnaean classification | A way of organizing living things. In biology, plants and animals have traditionally been classified by the structure of their bodies, in a descending hierarchy of categories: kingdom, phylum, class, order, family, genus, and species. |
| facts of Darwin | Charles Darwin : Considered the father of evolution. Origin of species does not say where species came from but where they they may have evolved . |
| Disease | abnormal condition, a disorder of a structure or function, that affects part or all of an organism. |
| Infectious disease | disease caused by a virus, bacterium, fungus or protist that is spread from an infected organism or the environment to another organism |
| Noninfectious disease | diseases that are noncommunicable and cannot be spread, sometimes called chronic diseases because they last a long time |
| Pathogen | disease producing organism |
| Vector | any agent (person, animal, or microorganism) that carries and transmits an infectious pathogen into another living organism. |
| Bacteria | unicellular microorganisms that have cell walls but lack organelles and an organized nucleus |
| Virus | infective agent that typically consists of a nucleic acid molecule in a protein coat, is too small to be seen by light microscopy, and is able to multiply only within the living cells of a host |
| Fungus | eukaryotic organisms that includes unicellular microorganisms such as yeasts and molds, as well as multicellular fungi that produce familiar fruiting forms known as mushrooms |
| Protist | unicellular or multicellular organism that can be plantlike , animal like, or funguslike. |
| Host cell | living cell in which a virus can actively multiply or in which a virus can hide until activated by environmental stimuli. |
| Replication | viruses can copy themselves by attaching to a host cell and using the cell as a factory to copy itself. |
| Mutation | enable viruses to adjust to changes in their host cells and are the reason why viruses such as the flu are different every year |
| Antibody | a protein that can attach to a pathogen and make it useless, if you have the right antibodies you are immune to a virus |
| Antiviral drugs | medicine that prevents a virus from entering a cell, antiviral drugs are only good for one virus and not all viruses have one |
| Vaccine | mixture containing material from one or more deactivated pathogens (usually viruses), helps bodies to form antibodies |
| Antibiotics | some bacteria produce these chemicals that limit the growth of other bacteria |
| Toxins | poisonous substances produced by some bacteria |
| Endospores | thick walled structures that some bacteria produce to survive during hard times |
| Epidemic | a widespread occurrence of an infectious disease in a community at a particular time |
| Pandemic | is an epidemic of infectious disease that has spread through human populations across a large region; for instance multiple continents, or even worldwide. |
| fact about diseases | bacteria are unicellular organisms , viruses are nonliving , fungus is fungi ( they're not plants but not animals ), a protist is an outside creature that causes some sort of a sickness. |
| influenza | virus |
| athletes foot | fungus |
| malaria | protist |
| giardia | bacteria |
| Renewable resource | an energy resource that is replaced as fast as, or faster than, it is used. |
| Nonrenewable resource | an energy source that is available in limited amounts or that is used faster than it is replaced. |
