Por qué el melanismo industrial es un tipo de selección direccional

Answers

El melanismo industrial es el fenómeno genético por el cual lepidópteros que viven en zonas industriales tienen un color oscuro. Este fenómeno se debe a que la selección natural favorece un determinado genotipo.

La selección natural es el principal mecanismo por el cual las especies y los organismos evolucionan (cambian) para adaptarse a su ambiente.

La selección natural se define como la supervivencia y reproducción diferencial de los individuos mejor adaptados a su ambiente.

Este proceso (selección natural) tiende a modificar las frecuencias de génicas (alélicas) y genotípicas las cuales determinan los rasgos adaptativos a lo largo de las generaciones.

La selección direccional es un tipo de selección natural que tiende a favorecer a un sólo alelo a lo largo del tiempo.

En el melanismo industrial, los lepidópteros (polillas) que expresan el alelo que codifica para el rasgo fenotípico 'color oscuro' se ven favorecidos porque esta característica les permite mimetizarse en un entrono ambiental oscuro causado por la polución ambiental de zonas industriales.

How can Earth’s layers be defined? Select the two correct answers.(1 point)

by their chemical compositions

by their physical properties

by their proximities to the core

by their amounts of land area

by their asthenospheres

Answers

Answer:

By their chemical composition

By their asthenospheres

Explanation:

The earth's layers can be defined with the help of the following facts:

By their chemical compositions. By their physical properties.

Thus, the correct options for this question are A and B.

What are the different layers of the earth?

The structure of the earth is generally categorized into four major layers. They are as follows:

The crust.The mantle.The outer core.The inner core.

Each of the above-mentioned layers has unique chemical composition. Apart from chemical composition, the physical state is also important when describing the different layers of the earth. The concentration of iron is found to be the highest in the core regions along with a little bit of nickel.

Therefore, chemical composition and physical properties are the two parameters that are used to define the different layers of the earth. Thus, the correct options for this question are A and B.

Answer:

Einsteins Theory of Relativity can be

supported with evidence of light doing

what around the sun?

In 1919 observation of a solar eclipse confirmed Einstein's prediction that light is bent in the presence of mass. This experimental support for his general theory of relativity garnered him instant worldwide acclaim. ... This has been measured directly and also through the gravitational redshift of light.

Answer:

The Earth moves around the Sun, due to the Sun's gravity. ... According to Newton's theory, the Earth should know immediately that the Sun had disappeared. But Einstein said that couldn't be right. Because, according to him, nothing can travel faster than the speed of light — not even the effects of gravity.

Explanation:

Albert Einstein, in his theory of special relativity, determined that the laws of physics are the same

for all non-accelerating observers, and he showed that the speed of light within a vacuum is the same no matter the speed at which an observer travels, according to Wired.

•Essentially, Einstein thought space and time were intertwined in an infinite “fabric,” like an outstretched blanket. A massive object such as the Sun bends

which molecule do indole positive bacteria cleave to form indole

Answers

In indole-positive bacteria, Tryptophan is used to form indole. This reaction is catalyzed by a tryptophanase enzyme.

Tryptophanase or tryptophan indole-lyase is an enzyme that catalyzes the reversible beta-elimination of Tryptophan to form indole.

Tryptophanase is present in many Gram-negative bacteria.

The indole-positive bacteria include Escherichia coli, Haemophilus influenzae, Aeromonas hydrophila, A. punctata, Bacillus alvei, Klebsiella oxytoca, etc.

On the other hand, the indole test is a test used to determine the ability of bacteria to convert tryptophan into indole.

Moisture hung in the air so thick you could almost see it sparkling in the dim sunlight. There were days, early in the summer like this one, where it seemed there was more water in the air than in the bay. We had beached the boat and stepped out on the recently cleared spit of land. The ground had a light dusting of white sand over an under layer of dried black mud. It looked like a recently frosted chocolate cake, though the frosting was spread a bit thin for my taste. The ground was solid, but we knew from experience that it was full of fiddler crab holes, and would be underwater at the first super-high tide. Mysteriously, to us anyway, someone wanted to build a house there.We often came to these spots to look for artifacts. Our beach, our summer home, had been a fishing camp for as long as anyone living could remember. The oldest stories told of travelers coming down to the edge of the sea, lining up to fill their wagon beds with salted fish to take back home. Old decaying cabins still lined the beach. Rotting nets, hung out to dry in the last century, decorated their weathered walls. Their broken faces spun stories in our minds. The fishermen who, tanned and wrinkled from sun and salt, hauled their nets full of splashing mullet in to cheers from the waiting crowds. The bounty of the sea lightened everyone's hearts, and the smell of roasting fish filled the damp air. Women fanned themselves from wagon seats. Children splashed in the shallow edges of the bay.
