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.
A small piece of black paper was folded in half and used to cover part of the top and bottom portions of a leaf on a living geranium plant. After the plant was kept in sunlight for several days, the paper was removed. The leaf was then boiled in alcohol to remove the chlorophyll and placed in Lugol's iodine solution. Only the part of the leaf that had not been covered turned blue black. This investigation was most likely testing the hypothesis that
Answer: Light is necesarry for photosynthesis to occur
Explanation:
Based on the information given in the question, the investigation was most likely testing the hypothesis that light is necesarry for photosynthesis to occur.
Photosynthesis, simply means the process by which green plants transform light energy into chemical energy. It should be noted that during photosynthesis, light energy is captured which is then used in the convertion of carbon dioxide and water, into oxygen and energy which comes in form of sugar.
Answer: This investigation was most likely testing the hypothesis that SUNLIGHT is necessary for photosynthesis
Explanation:
Photosynthesis can be defined as the process by which plants (green plants) use inorganic compounds such as carbondioxide and water to manufacture their own food. This process is not only important to plants but also to animals which depends on plants for food. The main features of photosynthesis include:
--> it takes place in chlorophyll of plant cells
--> Raw materials needed for this process are inorganic compounds such as carbondioxide and water
--> Final products are organic compounds such as sugar and oxygen as by product.
--> Energy needed for this process is gotten from SUNLIGHT which is absorbed by the chlorophyll.
To show that sunlight is necessary for photosynthesis, an experiment is performed as stated in the question above. Only the part of the leaf that had NOT BEEN covered turned blue black because the exposed part has been actively photosynthesizing due to the presence of SUNLIGHT. While the covered part didn't undergo any photosynthesis as it tested negative for starch when placed in Lugol's iodine solution.

O daltonismo é um distúrbio moderado ligado ao cromossomo X que se caracteriza pela cegueira para as cores verde e vermelha. Considerando-se o cruzamento de uma muher carreadora do alelo para o daltonismo ao se casar com um homem de visão normal, cuais as chances de as filhas desse casal serem carreadoras é de ?
Answer:
50%
Explanation:
Olá. Primeiramente é necessário informar que perguntas em português devem ser postadas no campo "world Languagens". Isso porque esse não é o servidor basileiro e sim o servidor americano. Caso contrario, a sua pergunta pode nunca ser respondida e até mesmo excluida do site.
Em segundo lugar, para que seja possivel que você repsonda a essa pergunta você precisará preencher um Quadrado de Punnett, como mostra a figura abaixo.
Como você sabe, as mulheres possuem os cromossomos XX e os homens XY. Como a mulher apresentada na pergunta acima possui o alelo para o daltonismo, mas não apresenta daltonismo, podemos considerar que apenas um dos cromossomos dela possuem esse alelo. O alelo para o daltonismo é recessivo, sendo assim, podemos considerar que essa mulher possui os alelos XDXd. Homem com quem essa mulher se casa, não possui daltonismo, logo os alelos dele são XDY, como mostrado na figura.
Ao preencher o quadrado de Punnett, você verá que existe a possibilidade desse casal possuir duas filhas, uma delas pode possuir os alelos XDXd, igual a mãe e, portanto, ser carreadora do alelo para o daltonismo.
Sendo existe uma chance, em duas filhas desse casal ter uma filha carreadora de daltonismo. Isso é igual a 1/2, que resulta em 0,5, ou 50% de chances de ter uma filha carreadora de daltonismo.
An oak tree falls in a forest. It kills some ants and stops grass from growing
below it. What type of disturbance is this?
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.

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.

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.
