The Division

Formation of the primitive heart Source: p contractions of the primitive heart start between the twentieth and twentieth first day. Contact information is here: MacroGenics. These movements occur for peristlticas waves that if they initiate in the venoso seio and they force the blood through the tubular heart, this blood if form in the wall of the vitelino bag during the third week of intrauterine life, passes for the venoso seio of the heart through vitelinas veins and crion for the umbilicais veins. The blood of the primitive heart is distributed for the brachial arcs come of the aortic arcs. Later that they liberate the oxygen and nutrients for fabrics and agencies in development of the embryo and it receives the dioxide from carbon and its products of excreo the blood returns mainly to the heart for the cardinal veins. The blood that passes to primitive placenta (crion) liberates its products of excreo for the maternal blood and from it receives the oxygen and nutrients, this well oxigenado blood returns to the heart for the umbilicais veins.

The primitive heart only possesss a forecourt and one ventricle. The division to atrioventricular starts for return of the completed half of the fourth week being to the end of the fifth week, these processes had occurred of simultaneous form suggested then events as the division of the canal primitive ventricular forecourt, primitive ventricle that if divides in right and left ventricle in the end of the fourth week if it communicates with the right ventricle and aorta with the left ventricle. Division of the arterioso bulb and arterioso trunk In the fourth week, if form tumefaes in the wall of the arterioso bulb call of Christians bulbares that they are involved for mesnquimais cells. The arterioso bulb is incorporated gradually for the walls of the ventricles, and in the adult right ventricle it is represented by the arterioso cone that if he originates from the pulmonary trunk.

Multiplicar Product

Four activities had been necessary to have repetition of numbers. Four stages correspond the 4 points. This game can be applied from 5 year of Basic Ensino. RULES OF the GAME 1) Each pupil chooses by lot a numeral of 6 numbers for the colleague. 2) Who gains the play to get more points, that is, what to carry through greater number of activities until a number is repeated. 3) Each pupil confers the work of the colleague. VARIATIONS the pupils choose by lot successively numeral formed of 5 numbers, 4 numbers, 3 numbers, 2 numbers. Another interesting game for bigger pupils is ‘ ‘ Guessing the age of one pessoa’ ‘ We can guess the age of a person asking for to it that it carries through the following calculations: 1 Escrever a number of two numbers.

2 Multiplicar the number written for two. 3 Somar five units to the gotten product. 4 Multiplicar this addition for fifty 5 Somar to the product number 1750. 6 Subtrair the year from the birth. The result that if it gets is a number of four numbers abcd. The two numbers of the right, that correspond to the sets of ten and the units, indicate the age of the person and, the two numbers of the left, that they correspond to the hundreds and to the thousands, they indicate the number that the person had thought.


Sin (b) and on the sin? What to say of the sin that, seeming not to have plus any meaning, if became, in saying of Mr. upports this article. Dawkins, a little healthful concern, one preocupaozinha boat for our lives. How to explain this so great practical insignificncia for the sin, ahead of the theoretical importance, so raised, that the Writing attributes it? As we learn, the sin meant the fall of the man and this has been an inheritance that deformed in some way all the descendants it first couple, men and women. Without little considering the probable transmission throughout the masculine ancestry, it is the question: if we are born imperfect, for the inheritance of a sin, of that type would be this defect – organic or moral? If he will be organic, we must find it where part of the body? E, being thus, as could be treated or be corrected? Or then, one will be moral or ethical, as it could be transmitted, infallibly, for as many generations, in all the times and places? It can be that it has sin, is clearly, when a person adulterates or when, in a homicide, it is taken off life of another person; or, until, who knows, when we antagonize the world where we live – poluindo the environment, what, in fact, it can bring illnesses and death. But, before this, it will be that the proper world in them has not been hostile? When we arrive at the world already we find to our wait pain, the illness, the oldness and the death. He will be that he would be correct to affirm that the man ruined the made world, at the beginning, very good for the creator? Would have the man the capacity to invent the illness and the death? The death, by the way, appears as proper necessity of the existence, essential to the life, therefore, as food the man kills animals; as food, animals kill animals and, also, as food, viruses and bacteria kill men and animals.


Bubbles From this image we can visualize as arrows indicated (Figure 10) the sprouting of bubbles in the material, formed during the process of manufacture of the iron carbon, where the rupture of the material occurs with more easiness. If the socket presented a graphite when sandpapered it would leave one black risk, in the studied steel did not have this graphite composition: the bubble only blew up. Figure 15? Bubbles? Incrustation Cementita Ferrite? Iron? Risks From this figure we can observe the ferrite presence brown color, cementita green color, incrustation/porosity black point, iron white color, risks in the horizontal line and diagonal line caused in the burnishing process, and bubbles formed in the manufacture of the steel carbon (it binds binary). 8 – CONCLUSION Therefore, from the presented data, the main conclusions of this work of which we carry through the assay is the study of metallurgic products, making possible to the determination of its constituent and its texture, generally carried through in previously polishing surfaces e, in general, attacked for an adequate reagent as in our assay. One notices that metallography is considered an analysis of great importance to also guarantee the quality of the materials in the process of manufacture and for the accomplishment of studies in the formation of new leagues of materials. This practical if becomes very complex and at the same time necessary, therefore the materials present different morphologies depending on the thermal treatments that had been applied it and also of the chemical composition employee, having to be analyzed before its application. Through the metalogrfica analysis of the steel it is possible to not only determine the classification of the steel, as well as, its physical, chemical composition and mechanics.

Biological Evolution

It had been analyzed the factors facilitadores and dificultadores. In accordance with the results were verified that the factors that intervene with the education of the Biological Evolution and that they are facilitadores leave of the interest that the pupil possesss in relation to the subject and of the curiosity in understanding as the beings had appeared livings creature, already the factors dificultadores is the ones that mainly involve religious questions and previous concepts of the pupils that do not accept or not ‘ ‘ acreditam’ ‘ in the Evolution for already arriving to the classroom with its opinion ‘ ‘ formada’ ‘. In view of such notes one becomes necessary, therefore to think about the education of the Biological Evolution not from doxa, but from questions properly of the scientific field, a time that in the classroom what pupil searchs in the dialectic/professor is knowledge scientifically proven. Word-key: Education; Biological evolution; Professors of Biology. The Biological Evolution can be defined as the responsible process for the changes of hereditary characteristics as group of organisms, populations and species throughout generations (FUTUYAMA, 2002). The Biological Evolution if presents as unifying element, through which, many factors as, the anatomical and physiological similarities between the species, the embryology and the diversity of the beings can be explained (GAYON, 2001). For Tidon and Lewontion (2004), the study of the Evolution it is capable to integrate Sciences Biological with other areas of the knowledge as Sociology, Mathematics, Computer sciences, Geology, History and Philosophy.
