Morphological Development (Development of multicellular organism, characterization and change)
Morphological development starts with a single cell which able to divide or die. The cells are joined by springs and formed the morphological individuals. One of the studies had done in India to determine the morphological characterization of Echinococcus from food producing animals. Cystic echinoccosis is a common infecting in food producing animals. In this research 21,861 animals had been examined and found the highest prevalence of hydatid cysts (5.10 %) followed by buffaloes (3.81%), pig (0.87%) and sheep (0.075%). (Pednekar, 2009,
Schramm, 2011). Another article had study on morphological development and characterization of aromatase and estrogen receptors alpha and beta in fetal ovaries of cattle. In this study the aim was to understand the role of estradiol-17β in fetal ovarian development, presence an localization of cytochrome p450 aromates (P450arom) and estrogen receptors alpha and beta proteins characterized in fetal ovaries of cattle. In the day of 110 of the experiment ovarian structures within different lobes appeared to be different morphological development stages. At the end of this experiment morphological development had analyzed that in granulosa cell growing of oocytes of follicles. Also both ERα and ERβ protein was observed in overigerous cords and granulosa cells and oocytes of follicles. (Burkart, 2009) Similar research had done by Celine Ferre, was “comparison of early morphological and molecular changes induced by 17-alpha-methytestosterone and estradiol benzoate in rat ovary.”(Ferre, 2013) The goal of this experiment was to identify early events and linked to morphological change in the ovary by exposure t...

...ent.” (Burkhart, 2010) After Ferre, studied the molecular and morphological changes induced by 17MT (an androgenic compound) and EB (estrogenic compound) on the rat ovary, scientist stated that “Our work indicated that the detection of early key hormonal markers in short term studies can help to predict the adverse long term effects on target” (Ferre,2013) End of the TGFα scientist concluded his experiment that “TGFα overexpression alone does not lead to tumor formation or epithelial hyperplasia in the mouse urogenital organs even though TGFα overexpression elicits bladder outlet obstruction.” (Yoshio, 2010) Morphological changes based on environmental factors, O’Regan stated that “focal palatine erosion” (FPE) can be developed by soft diet chetahs. Moreover, in several cases, this can lead to sinuses developing between oral and nasal cavities. (Yoshio, 2010)
Abstract: The objectives of this lab was to identify the internal and external anatomy of the fetal pig. The experiment was conducted by dissecting a fetal pig and actively seeing the external anatomy, Oral Cavity, Digestive System, Circulatory System, Respiratory System, Urogenital System, and Nervous System.

Estrus synchronization is the practice of regulating when one or many mares will be in estrus. Breeders can follow certain protocol in order to cause synchronization in the cycle. According to Samper (2009), there are three methods of inducing estrus. These are induction of luteolysis, prevention of estrus using progestins and progesterone with estradiol which allow natural luteolysis to occur and are almost always combined with a treatment for ovulation induction, and follicular ablation. This paper with examine and explore the hormones, methods, doses and protocols used to synchronize estrus in the mare.
Most people appreciate their hair as the most valuable assets especially for women. However, there are so many problems related to this precious thing nowadays such as hair loss (alopecia), dandruffs and premature greying and balding. The researcher’s team headed by Professor Markus Nothen from University of Bonn and Dr. Roland Kruse from Dusseldorf University in 2005 discovered that the main cause of alocepia is hereditary factors which either because of high androgen receptor formed or variant receptor which develops as a result of genetic change. In addition according to Hoffman (2002), “The most common form of alopecia in men is believed to be due excessive activity of androgens on the scalp where the hairs become miniaturized and pigment production is stopped.” Hamilton (1951); Hoffman (2002); Price (2003); Severi et al., (2003) claimed that conversion towards more potent testosterone is due to elevation level of 5-alpha reductase lead to common baldness. For the genetically derived phenomenon, it supposed to be totally about the hereditary cause and the other exogenous factors will be excluded. However, there are also views from proponents saying that some natural food involves in solving these hair—related problems for example emblica officinalis or amla.
Today’s article will take an objective look at the Echinacea plant and why some people take supplements, believing it will help them fight the germs.
When researching diseases that affect animals, I chose to research one that deals with cattle. This disease would be a reproductive venereal disease called vibriosis. Vibriosis can affect all breeds of cattle, male or female, and is the most important cause of infertility in female cattle along with occasional abortions. This disease is caused by bacteria that live in the crevices of a bull’s prepuce, of a bull aged four years or older (Hansen, 1914). Age is a factor because the foreskin of a bull does not develop until then. The disease is spread from an infected bull to a cow during breeding. A bull might be clean, but then infected by a cow who was infected by a bull before him. Many bulls can go years without showing any signs of this disease, whereas female cattle may lose a calf to an abortion the next coming calving season.

During recent years, numerous newspaper and magazine articles have suggested that humans may be at risk because small amounts of well known environmental contaminants, such as dioxin, PCBs and DDT, can affect hormone levels. Hormones are produced by the endocrine system as regulators of biological function in target organs. Because hormones play a critical role in early development, toxicological effects on the endocrine system often have an impact on the reproductive system. The term endocrine disruptor is used to describe chemicals that can mimic hormones and may either enhance or counteract their effects. It has been suggested that these hormone changes can, in turn, lead to a variety of health problems including cancer, decreased fertility, and abnormalities in newborns.
The chosen language for this paper is French. Morphology 1. Information on the language family it belongs to Language families are groups of languages that are related to each other because they come from a common older language. French comes from the Indo-European language family and is a part of the Romance family along with Italian and Spanish which was spoken a long time ago. 2.
Every woman when pregnant has a 3-5% chance of having a baby born with a birth defect, and these chances increase when the developing fetus/ embryos are exposed to teratogens, whether it’s intentional or unintentional (Bethesda (MD), 2006). Teratogens can cause severe birth defects, malformations, or terminate the pregnancy altogether (Jancárková, & Gregor, 2000). The placenta is known as an effective barrier from any detrimental pathogen that can potentially hurt the fetus. The timing of exposure of any teratogen is critical to the impact of prenatal development (Bethesda (MD), 2006). The most vulnerable time of the fetus for severe damage is during early pregnancy when all the major organ and central nervous system (CNS) are developing. Miscarriages have an important role in keeping a pregnancy from evolving when there is something serious going on with the developing fetus/embryo. Miscarriages are more common than we think and are the most familiar type of pregnancy loss (Bethesda (MD), 2006).
OSCC initiates in a multi-step process in which normal cells are transformed into preneoplastic cells and then to cancer9. During this process a sequential accumulation of genetic and molecular changes occur10. The majority of oral cancers are preceded by visible changes of the oral mucosa. Within the oral cavity lesions such as leukoplakia, erythroplakia, lichen planus and submucous fibrosis have a propensity for malignancy11. Oral potentially malignant disorders (OPMD) transform to oral cancers through various histopathological stages from hyperkeratosis/hyperplasia, to various degrees of dysplasia (categorized by mild, moderate, or severe according to the presence and severity of cell atypia and other structural aspects of the epithelium), to carcinoma in situ (CIS), and finally to invasive cancer12. Histopathological assessment for the grade of epithelial dysplasia is the most common method to determine malignant potential of patients with oral pre-cancerous lesion...
Language, like anything else, is in a state of continuous change. Language change takes place when a generation of speakers produces linguistic expressions that differ from previous generations of speakers. With every generation, words are borrowed from other languages, new words are invented, meanings of words change, and pronunciation of some words is altered. The process of language change might be slow or fast. However, as changes accumulate over time, the old and new language will extremely vary. For instance, symple, an old English word, is changed to simple. Also, speche is changed into speech. Language change is classified into typologies, like semantic change, sound change, lexical change, spelling change, syntactic change and other changes that play a role in the change of language overtime.

Morphology is a tool for a broad linguistic description and an analysis of words. The English morphology, as well as a morphology of any other language, may cause issues to the users of a language other than English to a certain extend. Since morphology covers units such as roots of words, affixes, prefixes, intonations and others it might be a challenge for users that do not come in touch with these numerous units. Such differences could be spotted by French speaking individuals. French language is an Indo-European language and is a part of the Romance family that includes Italian and Spanish. It is spoken throughout the world including Europe, America and Africa. Interestingly, English was influenced by the French language introduction to Britain which did result in similar grammatical features. These similarities don’t necessarily mean that both of these nations are capable of picking up the features of the other language. This is hardly ever the case.
