Gracias a una investigación internacional se ha averiguado que las actividades humanas causan estragos en los bosques tropicales al alterar el ciclo de nitrógeno normal. Los descubrimientos, publicados en Science, proporcionaron las primeras pruebas de efectos a largo plazo por contaminación de nitrógeno en árboles tropicales. Los científicos, de Austria, Canadá, Alemania y Panamá, trabajaron en dos emplazamientos remotos del Observatorio Terrestre Global del Instituto Smithsonian en Panamá y Tailandia. «La contaminación atmosférica fertiliza los bosques con uno de los nutrientes más importantes para el crecimiento», afirmó S. Joseph Wright del Instituto Smithsonian de Investigación Tropical en Panamá. «Comparamos el nitrógeno que contenían hojas de especímenes secos recogidas en 1968 con el de muestras de hojas de 2007. La concentración de nitrógeno foliar y la proporción de isótopos de nitrógeno tanto pesados ​​como ligeros ha aumentado en los últimos 40 años del mismo modo a como lo hicieron en un experimento anterior en el que se abonó el suelo del bosque. » El nitrógeno se origina en el interior de las estrellas gracias a temperatura y presión elevadas. En condiciones normales es incoloro, insípido e inodoro, y poco propenso a reaccionar con otras sustancias. En la atmósfera flota más del 75% del nitrógeno, que además es un componente esencial de las proteínas. Uno de los cambios que «activan» el nitrógeno viene producido por ciertas bacterias colonizadoras de raíces vegetales que extraen nitrógeno de la atmósfera y lo que significa o fijan en una forma útil para el crecimiento vegetal. Cuando las bacterias ya no necesitan el nitrógeno la planta lo absorbe, para luego pasar a los animales. La fijación del nitrógeno se define mediante el proceso de Haber, que convierte el proceso de nitrógeno gaseoso en amoníaco, un ingrediente común en los abonos. La fijación de nitrógeno por medios artificiales ha aumentado la cantidad de emisiones de nitrógeno reactivo en un 100%. Según los investigadores, el nitrógeno presenta dos formas o isótopos, átomos con la misma

Jobisdone [24]

Answer:

Option A

Explanation:

Renewable resources of energy are clean source of energy. They are sustainable as they are readily available, can be used again and again and do not produce any pollution neither during production stage nor during usage stage by an individual.  

There are very nations in the world which are oil rich and country itself has no oil reserve. In such scenarios, the dependency of nation on other countries increases. But in lieu to in-house renewable energy resources, country will not import oil from other nations  

Hence, option A is correct.

List some ways a DNA strand is similar to a ladder
ruslelena [56]
A DNA molecule is like a ladder because there are two sides (the sugar-phosphate backbones of the two strands) and rungs (each rung being a pair of complementary bases). Twisted, because the molecule is twined in a coil called a helix - or rather, a double helix because there are two strands.

Simora [160]

Answer:

The question lacks options, the options are:

A) 1 out of 16

B) 3 out of 16

C) 6 out of 16

D) 9 out of 16

The answer is 1 out of 16

Explanation:

This is a DIHYBRID cross because it involves two different genes coding for distinct traits. One of the traits will be dominant while the other recessive. Hence, parents that are purebred for opposite forms of the trait means that one parent is homozygous dominant while the other is homozygous recessive. When these two parents cross, they produce F1 offsprings that all possess the dominant trait but heterozygous/hybrids.

When these hybrids are self-crossed, they produce four different combinations of gametes which when crossed using a punnet square will result in F2 offsprings with a 9:3:3:1 phenotypic ratio according to Mendel's observation.

9 represents offsprings that are dominant for both traits

The two 3's represents offsprings that are recessive for one trait and dominant for the other respectively.

1 represents offsprings that are homozygous recessive for both traits.

Hence, 1 out of 16 offsprings will be homozygous recessive for both traits.

In place of thymine, what does RNA use as a base <br><br> Please help
11111nata11111 [884]
The first three are the same as those found in DNA, but in RNA thymine is replaced by uracil as the base complementary to adenine. This base is also a pyrimidine and is very similar to thymine. Uracil is energetically less expensive to produce than thymine, which may account for its use in RNA.
