In the animals that present direct development the individuals are, then from the birth, very similar to the adult state. After the fecundao, the eggs ranks for the female are presented constituted of: (1) egg yolk or vitelo, that it supplies the necessary nutrients the cellular divisions and the formation of the embryo; (2) embryo, that is restricted to the region of cicatrcula; (3) albmen or clear, that protects the embryo, cushioning the vibrations and the movements; (4) rind, of limy nature, whose membranes are permeveis, allowing the gaseous exchanges; (5) calaza, lace of albmen that insurance the egg yolk so that this can oscillate, any that is the position of the egg. With the progression of the embryonic development it is verified that the constitution of the egg if goes modifying, presenting in the end some embryonic annexes: crion, the allantois, the amniotic stock market or mnios and the vitelino bag. Throughout the embryonic development embryo goes suffering modifications. The birds try to always look a hotter place to aconchegar the egg.
STATE UNIVERSITY OF PIAUI-UESPI SUZANA ALINE DAYS YOU WOULD MAKE INTRODUCTION To deal with the pertinent subjects the biotechnology is being of great importance in the present time; therefore, the medias have divulged innumerable discovered attributed to the use of advanced technologies to the biotechnology. The boarding cell-trunk, for example, is a subject that if becomes current in TV reporters, periodicals, magazines, books. This subject must be boarded in classroom in order to guide, to enable and to inform to the pupils on these questions that if become controversies for society and is of utmost importance. In recent years the subject ' ' cells-tronco' ' he has been very debated, and it is object frequently displayed in the media. As the majority of the great new features, this area is being overestimated.
However, it does not have doubts of that its potentialities are enormous. In the truth, what if it has today are a series of perspectives and the results gotten in the experiences in animals of small transport, not being able still to be surpassed for the species human being. Therefore, it was decided to elaborate a Project of Biotechnology focusing one of its more varied subjects as the CLULAS-TRONCO, that it aims in recent years to inform the pupils on the advances of this subject. This will present to the pupils the advances of the biotechnology from the study of the cell-trunk. Recently, the Supreme Federal Court decided in favor of the research with these cells. A good information is essential and the school can give a great step, aiming at to make possible and to guarantee an action that helps the pupils of average education to more have an extended critical vision and on subjects of the daily one.
This project will be developed in the groups of 3 year of average education in the period of 23e 24 of November of 2010, in the Pertaining to school Unit Solange Viana hosted in the Promorar quarter in the Transversal Avenue of quarter S/N. GENERAL OBJECTIVE: To present the pupils of average education, simple form and descomplicada, concepts, ethical applications, potentialities and questions involving the cell-trunk study thus despertando a critical and brought up to date vision of the reality where they live. SPECIFIC OBJECTIVES? To approach basic concepts on cells and cell-trunk arguing some topics: classification, development and localization of the cell-trunk, as well as the main interests (use and study) and involved ethical questions with the subject. To present, through mini-courses, lessons and lectures on the cell-trunk. To debate with groups of pupils the subject argued with questionings, analysis criticizes and attainment of results. DEVELOPMENT the subject will be given through the accomplishment of lectures in form of mini-courses, expositivas lessons, research in informative periodical texts, magazines, visualization of videos in DVD or dates show. EVALUATION the evaluation will be made by means of the participation and interest of the pupil in the debates, reading and commentaries of texts and summaries of the presented videos. MATERIAL RESOURCES Date show, DVD, books, magazines, periodicals, research of Internet, acrylic picture. CRONOGRAMA OF APPLICATION the project will be executed in days 23 and 24 of November of 2010, through two lessons, being: 45 minutes of mini-course and 45 minutes of lecture with the participation and commentaries of the pupils.
This development, in turn, must enable the pupils to take decisions conscientious (Corazza-Nunes, 2006; Pedrancini et al, 2008; Pedrancini et. al, 2007; Rock and To sound, 2005). Therefore, the school must approach the Science of sistmica form, transdisciplinar and contextualizada, promoting an education that on the basis of makes possible to the citizens the appropriation of the knowledge which they can take decisions conscientious and clarified (Pedrancini et. al, 2007). If you are not convinced, visit Ali Partovi. The Biotechnology engloba some concepts and knowledge of processes such as organisms genetically modified, industry of milk, cheese and of the beer, products of fermentation, among others. The knowledge acquired from the concepts and of the processes allow the development of abilities of the associated pupils to a brought up to date vision of world, relating its processes and its chemical transformations (Serralheiro and Freire, 2002; Rota and Izquierdo, 2003). Taking by referring the education of chemistry, recent research discloses problems in the learning in the area of Sciences, is disclosed for the difficulties of the pupils in emitting opinions related to the scientific and biotechnological advances (Pedrancini et al, 2007). The pupils also keep alternative and confused ideas in relation to the contents treated in different levels of complexity. Add to your understanding with Ali Partovi.
The confused ideas and concepts on biological processes are associates the previous conceptions of the pupils and the valuation of the memorization of fragmented contents and the reproduction mechanics of the knowledge. Therefore he is allowed to infer that the education of Sciences nor always allows that the students apprehend the scientific knowledge in order to understand them, to question them and to use them to construct arguments or applies them in situations of the real life (Pedrancini et. al 2007, Rota and Izquierdo, 2003). The construction of knowledge in classroom depends on a shared process of teach-learning in which the meanings and the language of the professor must be adjusted to the characteristics and contexts of the pupils (Schnetzler, 2002).
The goals to reach the sustainable development using residues in the civil construction, must contemplate the recycling and the P& methodology; D (Research and Development), being basic for the effective market of the residues. 2. Development the support in the civil construction today is a subject of extreme importance, since the industry of the construction provokes a great ambient impact throughout all its productive chain. This includes land occupation, raw material extration, production and transport of materials, being that, the industry of the construction is one of the great collaborators of the partner-economic development. How much to the amount of materials, used for the construction of a building, they are expenses around a ton of materials, for a square meter, using great amounts of cement, sand, brita, etc. Even so, residues are generated due to the losses or wastefulnesses in this process; exactly that if it improves the quality of the process, will always have losses. The solid residues are responsible for a great ambient impact, that frequently in clandestine way, is deposited in strips of land, public areas and aterros, having its wasted potentiality.
Although this practical still to be present in the majority of the urban centers, can be said that in recent years it has diminished, in result mainly of the advance of the politics of management of solid residues. With the creation of the Resolution n. 307 of the National Advice of the Environment (CONAMA, 2002), that it determines lines of direction for an effective reduction of ambient impacts provoked by these materials, establishing that the generators are the responsible ones for the produced residue and that with priority objective must be not the generation and in case that is not possible must establish the reduction, reutilizao recycling establishing lines of direction, criteria and procedures for the management of these residues, classifying them in four different classrooms: , B, C and D Classroom? residues you reused or you recycle as aggregate (brick, concrete, etc); Classroom B? residues you reused/you recycle for other industries (plastic, paper, etc); Classroom C? residues for which viable technologies had not been developed that allow its recycling (plaster and others); Classroom D? residues dangerous (inks, solvent, etc), or contaminated (of radiological clinics, industrial installations and others).
