The Organism Chlamydia Trachomatis - The Organism Chlamydia Trachomatis Chlamydia trachomatis is a small bacterium that cannot grow outside a living cell. In this respect it resembles a virus, but it is actually a very sophisticated organism. There are two other related organisms: Chlamydia psittaci is widespread in animals and can be transmitted to humans. This organism in humans is an uncommon cause of severe pneumonia particularly when acquired from infected birds of the parrot (Psittacine) family, and occasionally of abortion following contact with infected sheep....   [tags: Papers] 675 words

My Favorite Microbe: Naegleria Fowleri - ... Contrastingly, the cyst is the alternative form of the microbe that cannot be found within the brain tissue. The trophozoite tranforms into the seven to fifteen micrometer cyst when the organism’s food source becomes scarce and the environmental conditions are not conducive to its growth due to cold weather, or other ensuing factors. As reported by Visvera, Moura and Schuster, “cysts are environmentally resistant in order to increase the chances of survival until better environmental conditions occur” (CDC, 2013)....   [tags: Biology, Organism]

In mariculture, microalgae either directly support all growth stages of bivalves, and larval stages of crustaceans and fish or indirectly are fed to artemia or rotifers, which are then fed on to later larval/ juveniles stages of crustacean and fish larvae through providing essential nutrients and other growth promoting factors (Cho and et al., 1999).Therefore, the nutritional property of microalgae offered to feed aquatic animals is crucial especially during the larval stages as well as their rapid growth rate and having an appropriate size for ingestion (Brown, et al., 1997)....   [tags: microalgae, aquatic organisms, animals, ] 633 words

Scientific Classification in Biology - Scientific Classification in Biology Classification in biology, is the identification, naming, and grouping of organisms into a formal system. The vast numbers of living forms are named and arranged in an orderly manner so that biologists all over the world can be sure they know the exact organism that is being examined and discussed. Groups of organisms must be defined by the selection of important characteristics, or shared traits, that make the members of each group similar to one another and unlike members of other groups....   [tags: Papers Biological Classifying Organisms Essays]

Benefits of Genetically Modified Organisms - Even though we may not know it, GMO’s are everywhere. From the trees in a lumberyard, the pets we own, and most common, the food on our plates. GMO’s are genetically modified organisms. They have even been called “part of the fabric of American life” (Lambrecht 3). New controversies have risen up to fight these “deadly” foods. Do we really know what we are eating. Does it even matter. Biotechnologies and altering the characteristics of food have been around for many centuries. These uses were put into use to create useful products such as wine and bread and more recently to create resistant crops and antidotes in the medical field....   [tags: Genetic Engineering ]

The Roles of Water in Living Organisms and as an Environment for the Organisms - The Roles of Water in Living Organisms and as an Environment for the Organisms Without water there would be no life on Earth; this is why water is the most important biochemical of all. In "Human Biology" by J.M Orten and O.W. Nevhans, it is suggested that 70% of all body weight is water, most of which is found in three major compartments: 70% intracellular fluid, 20% interstitial fluid (lymph) and 7% blood plasma, and only 3% in other compartments. By volume, nearly a half of each of our organs consist of water; amounting to approximately 10 gallons of water, of which most is in our cells....   [tags: Biology Essays] 539 words

The Role of Water in the Lives of Organisms - Water is essential to life itself; without water life on earth would not exist. Water is a major component of cells, typically forming between 70% and 95% of the mass of the cell. This means that we are made from approximately 80% water by mass and some soft bodied creatures such as jellyfish are made of up to 96% water. Water also provides an environment for organisms to live in, 75% of the earth is covered in water. The properties of water are essential for organisms to live in for a variety of reasons....   [tags: Papers] 1056 words

The Role of Water in Living Organisms - The Role of Water in Living Organisms Water is one of the most abundant molecules on planet earth; it is found in vast amounts not only in earthly enviroments (oceans, lakes and rivers), but is also present in the atmosphere, and as solid ice in the two poles. Consequently it is rather logical that water plays an important role in biological life: the origins of life occurred in water and life itself wouldn't be able to continue in it's absence .

The Importance of Diffusion to Living Organisms - The Importance of Diffusion to Living Organisms Diffusion is basically the movement of chemical species (ions or molecules) under the influence of concentration difference. The species will move from the high concentration area to the low concentration area till the concentration is consistent in the whole system. Diffusion mostly occurs in gases and liquids as these can move freely. The main features of an efficient diffusion system would be that it has a large surface area, thin membrane and a continuous supply of substances....   [tags: Papers] 733 words

The Biological Importance of Water as a Solvent and as a Medium for Living Organisms - The Biological Importance of Water as a Solvent and as a Medium for Living Organisms Water is possibly the most important substance life as we know it, as we need in order to survive; it also provides an environment for many species. All cells contain a minimum of 85% of water, with most fluids inside and outside of the cell likely to have at least 90% water. Both transportation of molecules and chemical reactions take place in dissolved water. In chemical terms, the water molecule is strongly dipolar, this property makes water a very effective solvent, particularly for crystalline salts .So, water is the solvent of the body & it regulates all functions, including the activity of everything it dissolves & circulates....   [tags: Biology Essays] 452 words

Dichotomous Key - Dichotomous Key Prior to evolutionary theory, scientists relied on similarity of physical characteristics to classify organisms. An 18th century naturalist, Carolus Linneas, developed a taxonomic classification system. This hierarchical system divides organisms into 5 kingdoms. Organisms visible to the unaided human eye fall into the plant, animal, or fungi kingdom. Kingdoms are then divided into phylum. This division is based body type and skeletal organization. Phylum are then divided into subphylum....   [tags: Papers] 542 words
