1. Decodable Text * There are five levels of decodable text‚ ranging from highly decodable to minimally decodable. Highly decodable books use one-syllable and one-vowel-sound words‚ such as “cat‚” “fun” or “sit.” These might also use some short sight words‚ such as “a‚” “an” and “the.” Very decodable text still uses simple words‚ but those words may now have an extra letter or use blends that the students are learning in class‚ such as “this‚” “such” or “that.” Decodable text adds more of

Charles Darwin published On the Origin of Species by Means of Natural Selection. Darwin’s book drew a cohesive picture of life by connecting what had once seemed a bewildering array of unrelated facts. Darwin made two major points in The Origin of Species: I. Today’s organisms descended from ancestral species that were different from modern species. II. Natural selection provided a mechanism for this evolutionary change. The basic idea of natural selection is that a population can change over

There are many words to describe the 1930s‚ but equality was not one of them. From injustice lynching and kills of blacks to the stock market crash of 1929 that lead the United States into the Great Depression. The 30s plausible could be the worst years in US history. In “To Kill a Mockingbird” by Harper Lee‚ she uncovers all the hardships there were living during that time period. The story takes place in Maycomb a small town in Alabama and is narrated by the main character‚ a little girl named

relatively few species from many different classes of Ascomycota‚ whereas tropical endophyte assemblages are dominated by a small number of classes with a very large number of endophytic species. The most easily cultivated endophytes from tropical plants have wide host ranges‚ but communities are dominated by a large number of rare species whose host range is unclear. Even when only the most easily cultured species are considered‚ leaves of tropical trees represent hotspots of fungal species diversity

Species Interaction * The relationships between two species in an ecosystem. * The interactions between two species need not be through direct contact. Species may affect each other through intermediaries such as shared resources or common enemies. Major factors in evolution and adaptation: * Predation * Competition for scarce resources Terminologies: * Habitat – the actual physical location where a species lives. * Conditions – physical or chemical attributes of the

Endangered Species Endangered species are living things whose population is so reduced that they are threatened with extinction. Thousands of species are included in this category. The International Union for the Conservation of nature and Natural Resources publishes a list of threatened mammals‚ birds‚ reptiles‚ amphibians‚ and (many people do not consider them) plants .CAUSES OF EXTINCTION Millions of years before humans‚ extinction of living things was linked to geological and climate‚ the

( It is a loner animal that doesn’t like to live in groups.)} The strongest (female-male) is the leader of the group. So‚ It leads them for their hunt or fighting. First of all‚ this animal uses different sounds to communicate together. For example‚ It moans to show it is unhappy. It sometimes howls to keep the group together. It usually trumpets when it is frightened or in danger. It also groans to warn its group of danger saying "Danger ahead". It may howl to begin the hunt or to return to

A keystone species is a species that has a disproportionate effect on its environment relative to its abundance. Such an organism plays a role in its ecosystem that is analogous to the role of a keystone in an arch. While the keystone feels the least pressure of any of the stones in an arch‚ the arch still collapses without it. Similarly‚ an ecosystem may experience a dramatic shift if a keystone species is removed‚ even though that species was a small part of the ecosystem by measures of biomass

altered and modified‚ but these tend to happen at a gradual pace. This allows most species to adapt to the changing environment‚ where only a slight impact may take place. However‚ when changes occur at a fast pace‚ there is little or no time for an individual species to react and adjust to the new circumstances. This cause disastrous results‚ and for this reason‚ rapid habitat loss is the primary cause of species becoming endangered. Nearly every region of earth has been affected by human activity
