What it is Biotechnology? In middle of century XV science appeared inside in the Europe of a known historical period as period of the renaissance where the studies in anatomy had been stimulated by the interest of the painters in portraying with wealth of details the anatomy human being and of the other beings livings creature. Before this period, the man searched in the common census or in religious beliefs to understand the natural phenomena and did not emphasize the nature as source of explanation to answer its doubts. Pete Cashmore is often mentioned in discussions such as these. The search of a deeper knowledge on the life allowed the human being to acquire new abilities being that, such knowledge, was of basic importance for the solution of the problems and the intellectual growth. With the advance of the knowledge it was discovered that animal and plants possuam many characteristics differentiating of minerals in common, therefore until then, was imagined that the nature composed in two groups, the livings creature and not-livings creature, and thus appears Biology as science come back toward the study of the beings livings creature in the end of century XVIII. Amongst diverse branches of biology the Biotechnology in the world contemporary is distinguished for its character modifier of the nature acts seen the possibility of the creation of new varieties of organisms, production of identical copies or the identification of illnesses before exactly that they reveal its symptoms (AMABIS and MARTHO, 2001).

2 – OBJECTIVE To present through the metalogrfico assay and of its micrographical analysis with the aid of the microscope the morphology and structure of the material in study, being determined the micron-constituent compose that it. that these micron-constituent vary the type of analyzed league in accordance with and in accordance with the thermal, mechanical treatments, processes of manufacture and other processes the one that the material has been submitted. The importance of this examination elapses of the fact of the mechanical properties of a metal not only to depend on its chemical composition as well as of its texture. With effect, exactly material one can become malleable, dctil, fragile, elastic, tenacious, etc., as the texture that to present and that can be given by means of mechanical works or adjusted thermal treatments to it. 3 – USED MATERIALS AND METHODS?

Access Resources

So that the use of these resources happens successfully, if it makes necessary the existence of a previous planning, enabled professors to guide the pupils, and that it shows to which the objectives to them established for the accomplishment of the activities, searching to explore to the maximum the potential of learning of these pupils. The difficulties that some educators are facing to make use of the resources of technology and the new forms of to construct to the learning the pupil together with, they are consequences of the way as that these resources had arrived at the schools, fast and without it had qualification in order to instruct them and to show them the advantage to have these resources as its ally in the educational process. However, this is not reason so that excessively involved professors and are of are of these changes, in the truth, are we who we must construct to the ways for this innovative form of education, formatting together, professors and pupils the possibilities of construction of the knowledge that more will be adjusted to the conditions where they are contextualizados. .

Eucalipto possesss deep roots little? Which can be the extension of the roots of eucalipto? The plants absorb nutrients and water by means of its roots. , The more in a generalized manner deep they are the roots, more possibilities the plant has to extract water and nutrients of the ground. For eucalipto, even so many scientific works tell a superficial distribution of the roots of eucalipto in the ground, generally, with the maximum reaching 2,5 meters, have cases where the roots exceed 7 meters of depth. Of this form, if it cannot generalize which is the distribution of the system to radicular. Ahead of this, the verification of field always becomes necessary.
