biology and subsequently adopted in the considerations developed in ecology. Subsequently, the term was extended including the human and the concept of human habitat that has evolved in its meaning since the 70s emerged. Of its assimilation as human settlements and more specifically as housing, it became related to the urban problems of cities and even to be a concept defined as a spatiality of society, until today it is already seen in a more comprehensive way. Now the habitat is understood not only from its physical dimension, but also from its political, economic, social and environmental dimension, and even as a condition to create a citizenship that makes possible a more democratic city. The...

biology, this is known as sexual dimorphism. The dorsal fin is also an indicative to distinguish some specimens from others. Some experts, based on morphological and molecular studies, have come to determine that there are different types or ‘species’ of orcs, and each of them corresponds to a concrete morphology of dorsal fin. Well, related to this dorsal fin, a worrying phenomenon has been observed: the orcs in captivity have lost the rigidity of their dorsal fin. Why is the dorsal fin folded in orcas in captivity? The proliferation of aquatic parks has revealed this abnormal fact. Although it has also been observed in Orcas in freedom, more and more orcs are observed in captivity with the...

biology. So that the genetic information contained in the DNA is maintained through its replication capacity. The information contained in the DNA is expressed giving rise to proteins, through the transcription processes, step by which the information is transferred to a messenger RNA molecule (RNA-M) and, through the translation process the message transported byRNA-M translates into protein. DNA replication is given as the two strands of the original DNA molecule, the nucleotides of each strand attract free complementary nucleotides. Once they have totally unwound, they will have created two DNA molecules, each identical to the first, it is important to mention that the replication does not always...
Biology, 2016). The previously raised definitions make it clear that bioengineering and biotechnology work jointly to the benefit of the human being and its environment, this environment formed not only by its peers but also by nature with its biotic and abiotic agents. The most obvious way to explain the relationship of the environment with the human being is through examples, if we remember some years ago the farmers used large amounts of pesticides and insecticides to improve their crops, these were gradually deteriorating the layer of the layer ofOzone and currently this destruction causes countless diseases in human beings, thanks to biotechnology and bioengineering agriculture has had a...

biology, medicine, material and electronics. The science of materials here is involved nanotechnology because now the nanoparticles give new properties (within these they make them more resistant to scratch, corrosion, etc.) and reinforce the materials. Example today, there are already some nanotechnological products around us, such as more resistant and light tennis rackets thanks to the use of carbon nanotubes, cosmetics with nanoparticles that facilitate their absorption and coatings that thanks to nanoparticles prevent the deposition of dirt. Nanomaterials and nanotechnology stand out enough in the new advances in modern medicine since thanks to this science you can obtain miniaturized...

biology of stem cells is the non -standardized cultivation protocol, translating into different cell preparations (different derivation techniques);If a standard methodology is not established, research can lead to a dead point, since there is no comparison that can be made when it is not coming from the same germinal line. A solution to this problem is an internationally coordinated work where some derivation and cultivation protocols were established developing regulatory frameworks that guide the activities, on the other hand, the creation of an “Embryonic stem stem cell international bank” would be doubly beneficial: Guarantees homogeneity. · The researcher would have more time to...
