Trichomonas Vaginalis
T. vaginalis is a pear-shaped organism that moves itself with four whip-like flagellas that protrude from its front end. A fifth flagellum attached to a flowing membrane that extends rearward. T. vaginalis is a non civilized eukaryotic organism that is in most respects similar to other eukaryotes, but its energy metabolism bears a stronger resemblance to that of anaerobic bacteria. Trichomoniasis is a very common sexually transmitted disease (STD) that is caused by infection with the protozoan parasite called Trichomonas vaginalis. Even though the symptoms of trich varies from host to host , most people who have STI parasite can't tell they are infected. The scientific name is Trichomonas Vaginalis. More common names are trich, vaginitis, ureitis. Trichomonas vaginalis is one of the common sexually transmitted microorganisms in the world, with an estimated 170 million cases occurring each year. The disease is still poorly understood, and some practitioners continue to question its value. However, there is growing evidence that shows that T vaginalis is an important pathogen, in its own right due to the “immediate” morbidity associated with the disease, and more importantly for its role in the promotion of premature rupture of membranes, premature labor, and low birth weight and the likely capability of getting HIV. While a slightly increased risk for HIV (Bowen,2000) transmission may have minor significance for an individual, it may be of considerable value at the community level. T vaginalis was first discovered by Alfred Donne in 1836, when he notice the presence of motile microorganisms in women with frothy vaginal discharge and pruritus. (Beigi,2012) Decades later In the United States, the number of T. vaginalis infections among sexually active women was measured 2 to 3 million symptomatic infection annually.(Beigi,2012) it may survive in the host for 2+ years and symptoms several weeks after exposure; The parasite does not survive well in external environments. Trichomonas vaginalis live in the female lower genital tract and the male urethra and prostate, where it duplicates, it may live in the host for 2+ years and symptoms usually appear in women within 5 to 28 days of exposure, The parasite does not survive well in the outside surroundings. Trichomonas vaginalis are transmitted ONLY by humans, which is...

An Watermarked Blackbox? : There is more to human organism than an invisible blackbox

1495 words - 6 pages of behaviors. Whereas behaviorism concerns primarily with the direct S-R associations, social cognitive theory concerns considerably with the indirect personal factors of why and how such S-R associations are made in terms of awareness or expectations of the consequences of behaviors. Thus learning in social cognitive theory acknowledges that learning has something to do with mental process, viewing human organism as a watermarked blackbox—which means that human mind is still black box but somewhat visible (i.e., considerably influences on learning).

It will be argued that all different theoretical models of society can be useful, but that the model ‘society as an organism’, which emphasises symbolic interactionism, is often more useful than structural functionalism on its own. My analysis will start with a look a critique of

Organism reproduction with an emphasis on meiotic cell disivion

897 words - 4 pages Organisms can reproduce by two processes, asexual and sexual reproduction. Asexual reproduction is the production of offspring by a single parent. Offspring produced asexually inherit their DNA from only one parent and are genetically identical to that parent. Reproductive processes that involve obtaining genetic information from two parents that involve the union of a sperm and an egg is called sexual reproduction. A sperm and egg individually
