Colleen McCracken Mrs. Doll Hon Biology 28 April 2017 Saltwater Biome “Dream big.” “Bigger is better.” One may have heard many phrases about “big” or “bigger.” But why not say “Dream saltwater biome.”? After all, the saltwater biome is the largest biome on Earth and covers roughly 70% of our planet (KDE Santa Barbara 1). A biome is a community of both flora and fauna in a large habitat (Postlethwait and Hopson). The saltwater biome is a community in a saltwater habitat. This group of similar…

Introduction The purpose of this statement is to address the recent changes to the South Carolina Curriculum Standard. Research will be conducted on both Evolutionary theory and Intelligent Design theory to determine if high school biology teachers should teach their students Intelligent Design as a valid alternative to Evolutionary theory. Intelligent Design The Intelligent Design theory argues that the world and all the creatures in it were created not by random mutations and evolution, but…

James Lovelock, fundamentally formulated the theory that our Earth is unique and complex because the Earth is a self-regulating system that replenishes itself for the species, in order to maintain homeostasis, within the system. Lovelock interestingly familiarizes our Earth to the nature of human beings, such as the Earth’s skin are forests that sweat to preserve the cooling of the Earth, while the oceans are rivers of blood that flow through the veins of Earth transporting nutrients and washing…

system, they require certain nutrients to be readily available. Because of this, another mechanism takes place, whether it is the movements of coelomic fluid or the exchange of gases and wastes by each cell being exposed to water. In the case of flatworms, a thin body wall replaces the circulatory system. Diffusion takes…

parasitic worm that can be found in many organism in the Great Barrier Reef, but when it attaches itself to a snail, the snail instead of reproducing snails reproduces parasites instead.(13) Monogenea and Southern Fiddler Ray: Monogenea are parasitic flatworms that are virtually invisible to the human eye, it feeds off the skin of its host and is undetected by other predators.(14) Human impacts on the Great Barrier Reef: Overfishing: Since fishing is now done by using nets attached to boats…

Invasive species are easily comparable to the explorers of the old days. Explorers could be helpful by introducing new supplies, like horses, during the big Columbian Exchange. Explorers could also be largely negative, bringing disease and slavery into the nations they conquered. Explorers sometimes just set up trade relations and left well enough alone. Much like these explorers, invasive species have the propensity to help, hurt, or assimilate into their new surroundings. Experts on invasive…

Kingdom: Animalia Phylum: Porifera Classification information for Poriferans: Poriferans, better known as sponges, consist of 5000 known species, all located primarily in marine and fresh waters (Myers, 2001a). They are multicellular, heterotrophic, invertebrates with an irregular shape and no distinct pattern of symmetry (Myers, 2001a). Overall, they are the simplest of animals; thus, lacking any true tissue and/or germ layers (Myers, 2001a). Furthermore, they are known to be highly sessile,…

1.Definition of Ambiguity Ambiguity, as is defines in the Webster’s Third International Dictionary, is”the condition of admitting of two or more meanings, of being understood in more than one way, or of referring to two of more things at the same time.” In ordinary books on linguistics, the term is generally defined roughly as a linguistic phenomenon that a word, phrase or clause can have more than one possible interpretation. It is thus an attribute of any idea or statement whose intended…

Revolution against the basic evolutionary developmental biology arises with the astounding repair capacity of the planarian robust self assembly system and its automatic repair ability of its body structures. With its complex body plan and nervous system, a planaria possess the ability to flawlessly regenerate any part of their body after a traumatic injury or loss. It is capable of recovering its original structure and function of any damaged or obliterated body part even after being deprived…
