Investiga un uso beneficioso (medicina o industrial) para las bacterias, virus y Hongos microscópicos. Explica brevemente su utilización.
Answer:
- Hongos: antibiótico penicilina
- Bacterias: producción de insulina para uso humano
- Virus: vectores basados en adenovirus para el desarrollo de vacunas
Explanation:
Los microorganismos son fundamentales para el desarrollo de diferentes tipos de aplicaciones industriales y medicinales. Por ejemplo, la penicilina es una sustancia sintetizada por el hongo Penicillium notatum, la cual es ampliamente utilizada como antibiótico debido a sus propiedades antibacterianas. Las penicilinas son antibióticos del grupo de los betalactámicos que tienen como núcleo un anillo central de beta-lactama, las cuales son capaces de destruir una amplia variedad de bacterias. Por otra parte, las bacterias pueden ser usadas para la generación de moléculas orgánicas con fines médicos. Por ejemplo, cepas de Escherichia coli han sido modificadas mediante técnicas de ingeniería genética con el objetivo de producir insulina humana, una hormona central en el metabolismo de la glucosa. Mediante técnicas de recombinación genética, el gen responsable por sintetizar insulina humana ha sido introducido en bacterias. Las cepas de E. coli son relativamente fáciles de cultivar en el laboratorio y por lo tanto permiten obtener grandes cantidades de esta hormona (insulina). Finalmente, existen ciertas tipos de virus inocuos para nuestro organismo los cuales han sido recientemente utilizados como vectores para el desarrollo vacunas. Mediante esta técnica de ingeniería genética, un determinado vector viral (por ejemplo, un virus de la familia de los adenovirus) es modificado genéticamente con el objetivo de insertar un fragmento de un agente infeccioso o 'antígeno' el cual individualmente es incapaz de producir daño. Las vacunas diseñadas a partir de vectores virales son inofensivas para el organismo pero son capaces de desencadenar una respuesta inmune contra el antígeno recombinante, generando de este modo una memoria inmunitaria en contra el agente infeccioso.

Javier investigated what happens when Earth's plates meet. He found that as Earth's plates meet at plate boundaries and interact, they move in three different ways. The ways they interact produce changes on land and on the ocean floor. What are the kinds of boundaries that plates form? Label each plate boundary with the correct type from the choices below.
Answer:
I. Divergent
II. Convergent
III. Transforming
Explanation:
The crust is the outermost layer of the earth. It is divided into many plates that move over the mantle. Nowadays, there are six different bigger plates and twelve that are smaller. These plates are limited by three types of ridges or borders that differ in the movement they produce.
Boundaries types:
I. Divergent: New crust is created by the rising molten materials coming from the mantle. Two plates separate, and the stream of hot material creates a new seabed between them. It occurs an expansion of the sea bottom. As old plates get separated, the new and young crust instantaneously gets formed. The emerging mantle occupies the space left by the separation of the two plates. This process occurs along with an underwater mountain range, known as the mid-oceanic ridge or divergent ridge. An example of this is the ridge located in the middle of the Atlantic Ocean, extending from Greenlander to the southernmost point of South America.
II. Convergent. Collision area between two plates. Two oceanic plates might collide, or one oceanic plate with a continental one. In this last case, the oceanic crust sinks under the continental plate, and magma rises to the surface by crevices. The thicker and older plate subduces under the other plate. The Himalayas and Los Andes are examples of these collisions. Also, collisions create volcanic arches and continental arches.
III. Transforming. The plates slide laterally with each other, and they are usually called faults. It is associated, in general, with the oceanic ridge, although it might also occur in the continental plate. No rocky material is either destroyed or formed. When the plates move and produce a displacement of one transforming limits from side to side, earthquakes occur. The movement breaks the crust and originates pronounced fractures. The San Andrés fault is an example of this plate ridges.
The kinds of boundaries that plates form is the fact that seismic activity takes place at the three known types of plate boundaries called divergent, convergent, and transform.
What happens when Earth's plates meet?If two tectonic plates meet, they create a kind of convergent plate boundary.One converging plates often shift or move below the other, in an act known as subduction.
The new magma (molten rock) tend to increase and may erupt to create volcanoes.

O A. Secondary
O B. Primary
O C. Cyclical
O D. Small
Answer:
This is O D. Small type of disturbance.
Explanation:
Small-scale biological disturbance.
Answer:
O D. small
Explanation:
In ecology a disturbance is an event that causes a change in the environment. There are small-scale disturbances and high-magnitude disturbances. Small-scale disturbances are typically driven by biological processes -for example the fall of a tree- while high magnitude disturbances are typically driven by physical processes -for example, storms-. Small-scale disturbances as single-tree blowdowns are very important to create and maintain diversity and heterogeneity in the forest.

Without knowing the genetic differences of the birds, how can we know that cardinals and finches are likely more closely related to each other than cardinals and finches are to woodpeckers? Cardinals and finches live in more similar habitats. There is no difference in their relatedness; because they are all birds, they all evolved at the same time from a common ancestor. Cardinals and finches have more morphological similarities. Fossil records show that cardinals have been around longer than woodpeckers and sparrows.
Answer:
The correct answer is - Cardinals and finches have more morphological similarities.
Explanation:
To find out the relatedness of the different species or organisms one can use genetic mapping to find precise relatedness, however, if one can not find the genetic differences of the organism one can use the morphological similarities and differences to find out how closely they are related.
Homologous structures and analogous structures are two major morphological characters to find how closely related cardinals and finches are than cardinals and finches are to woodpeckers.

Explain how this mutation will result in competition within the population that is linked to the idea of survival of the fittest.
Answer:
Survival of the fittest, term made famous in the fifth edition (published in 1869) of On the Origin of Species by British naturalist Charles Darwin, which suggested that organisms best adjusted to their environment are the most successful in surviving and reproducing. Darwin borrowed the term from English sociologist and philosopher Herbert Spencer, who first used it in his 1864 book Principles of Biology. (Spencer came up with the phrase only after reading Darwin’s work.)
Herbert Spencer's Principles of Biology (1864) first introduced the expression “survival of the fittest.”
Survival of the fittestQUICK FACTSKEY PEOPLEAlfred Russel WallaceHerbert SpencerRELATED TOPICSAdaptationNatural selectionDarwinian fitnessUse in evolutionary theoryDarwin did not consider the process of evolution as the survival of the fittest; he regarded it as survival of the fitter, because the “struggle for existence” (a term he took from English economist and demographer Thomas Malthus) is relative and thus not absolute. Instead, the winners with respect to species within ecosystems could become losers with a change of circumstances. For example, fossil evidence supports the notion that the mammoth (Mammuthus) was more fit during the most recent ice age (which ended roughly 11,700 years ago), but it became less fit as humans hunted it and the world’s climate warmed; fossil evidence suggests that the mammoth succumbed to extinction a few thousand years later.
Darwin’s theory of evolution by natural selection entailed three crucial elements: variation, reproduction, and heritability. Variations in the physical features of organisms that tend to benefit an individual (or a species) in the struggle for existence are preserved and passed on (or selected), because the individuals (or species) that have them tend to survive. The success or failure of a given variation is not known when it emerges; it is known only retrospectively, after organisms that possess it either grow and mature and pass it to their own offspring or fail to mature and reproduce.
Importantly, Darwin was influenced by the thinking of English physicist and mathematician Isaac Newton, whose system emphasized experimentation, mathematics, and logic over subjective sense experience. During Darwin’s time, his evolutionary theory was an attempt to construct a similar system for the living world, a frontier not yet crossed in the biological sciences.

Some philosophers and scientists have suggested that the notion of survival of the fittest is an example of circular reasoning—that is, a tautology (a statement framed in such a way that it cannot be falsified without inconsistency). In tautologies, any true statements that follow are a matter of definition. Indeed, describing those that survive as the fittest is similar to stating that those that survive survive. British philosopher Karl Popper considered “survival of the fittest” self-evident at first; however, he changed his mind after realizing that Darwin posited variation axiomatically; that is, Darwin noted that all individuals did not start with the same set of characters (or traits). Therefore, the forces affecting survival did not weigh on individuals and species equally; there were always variations, some of which would prove favourable and confer fitness over others.
