Solar energy is defined as the energy produced by the sun and is the major

source of energy on earth. It is beneficial to plants in the ecosystem.

The solar energy is absorbed by the atmosphere through compounds such

as:

These substances absorb about 71 percent of the solar energy which is

approximately equivalent to  three-fourths of it.

Explanation:

Answer:

The answer choices were:

Explanation:

A. Genetic testing could cause harmful mutations.

B. Genetic testing could improve the diagnosis of disease.

C. Genetic testing could cause job discrimination by revealing health risks.  

D. Genetic testing could cause ecosystem damage by accelerating evolution.

Answer:

Anolis is involved in the two green and brown species of anole speciation processes. Speciation is the process caused by evolution that results in the development of collective genetic changes during a period of time due to adaption or geological or environmental conditions.

The evolution of these two species is due to the difference of the niche or geological difference likewise here the niches of both green and brown Anoles among species in relative size as well as color and pattern.

Answer: The correct answers are "ionizing radiation", "codon errors" and "failure of repair by ligase"

Explanation:

Some agents of mutation that can affect the genes of humans are ionizing radiation and codon errors as well as failure of repair by ligase.

Genetics has been known as the study of the heredity as well as the variation of the inherited the characters and the genetic properties and the organism's feature and the characteristics. It has been also known as the branch of biology that has to deal with the study of genetic variation, genes, and the heredity in the organisms.

The main function of the DNA has to carry the information from one generation to the another generation this has been the reason due to which DNA has been also known information molecule.

The main function of mRNA has to work as the immedieter between the protein and DNA which has been utilised by ribosome for the process of direct synthesis of protein, and the function of tRNA has to carry the accurate amino acid to the proteins synthesis site which takes place in ribosome.

Therefore, Some agents of mutation that can affect the genes of humans are ionizing radiation and codon errors as well as failure of repair by ligase.

The form correct pairs can be matched with the parts of fruits as;

The epicarp, which is the outermost layer, the mesocarp, which is the middle layer, and the endocarp, which is the inner layer enclosing the ovaries or the seeds, are the three separate layers that make up the pericarp in fleshy fruits.

The fruit's exterior surface is made up of the exocarp, the fruit's top layer. The tissue between the exocarp and endocarp is called the mesocarp. The innermost layer, called the endocarp, is situated just outside the seed coat.

Answer:

El fósforo (P) es esencial en todas las formas de vida conocidas, dado que constituye un elemento clave en muchos procesos fisiológicos y bioquímicos. Se trata de un componente presente en todas las células de todos los organismos vivos. El fósforo aparece en estructuras complejas de ADN y ARN que, al contener y codificar la información genética, controlan todos los procesos biológicos en las plantas. Además, el fósforo es un componente fundamental del sistema de transporte de energía en todas las células.

El fósforo no aparece aislado en la naturaleza, sino que se encuentra siempre combinado con otros elementos con los que forma los fosfatos que pueden ser muy complejos y presentarse bajo distintas formas en los suelos, el agua, las plantas, los animales y el hombre. Por tanto, se utilizará la palabra “fósforo” de forma genérica en lugar de identificar el fosfato concreto, aunque en la mayoría de los casos, se ofrecerán valores numéricos como P2O5 .

Hasta una época relativamente reciente, el crecimiento de las plantas y de los animales, y por extensión, la productividad de la agricultura, se veían limitados por la falta de fósforo, ya que anualmente solo se disponía de unas pequeñas cantidades de las rocas y de los minerales del suelo gracias a la acción erosiva de los elementos. Cuando los agricultores comenzaron a utilizar fertilizantes en el siglo XIX, los niveles de fósforo disponible para las plantas en muchos suelos eran todavía muy bajos. Por eso, hasta que no se comenzó a aplicar fósforo, la respuesta a otros nutrientes, especialmente al nitrógeno, era muy pequeña, es decir, que el fósforo era el nutriente limitante del crecimiento de las cosechas.

El fósforo desempeña un papel fundamental en la fotosíntesis, proceso por el que las plantas absorben la energía del sol para sintetizar moléculas de carbohidratos, es decir, de azúcares, que son transportados a los órganos de almacenamiento de las plantas. Este proceso es esencial para todas las formas de vida y constituye el primer paso en la cadena para producir alimentos, piensos y fibras.

Las raíces de las plantas absorben el fósforo del agua presente en el suelo y que se denomina solución acuosa del suelo.

Sin embargo, los compuestos de fósforo no son muy solubles y, como consecuencia, la cantidad de fósforo que la planta puede tomar de la solución acuosa del suelo tiende a ser mucho menor de la que necesita, especialmente cuando la planta se encuentra en un periodo de fuerte crecimiento. Por eso, el fósforo de la solución acuosa del suelo debería reponerse con una frecuencia de diez veces al día en esos periodos.

En un día, una cosecha de rápido crecimiento puede absorber el equivalente a cerca de 2,5 kg de P2O5 por hectárea (una hectárea equivale a 10.000 m2 ). De esto se deduce, por tanto, que es necesario que existan reservas adecuadas de fósforo en el suelo y que esas reservas puedan estar disponibles con facilidad. La mayoría de los suelos no abonados contienen una cantidad demasiado pequeña de fósforo, fácilmente aprovechable, para dar respuesta a la gran demanda de las cosechas, en especial durante ciertos periodos del ciclo de crecimiento. De ahí, que se imponga la necesidad de aplicar fertilizantes que contengan fósforo.

La carencia de fósforo afecta no solo al crecimiento de la planta y al desarrollo y rendimiento de la cosecha, sino también a la calidad del fruto y a la formación de las semillas. Asimismo, la carencia de fósforo puede retrasar la maduración de las cosechas, con lo que se retrasa la recolección y se pone en riesgo la calidad del producto.

Answer:

Top to bottom: 5, 3, 2, 4, 1

Explanation:

I'll take a shot! Here I go!

5 (Sun) = top; we get all our energy from the sun

Then 3 (plants); plants can convert sunlight into food for themselves via photosynthesis

Then 2; we're talking about herbivores that eat plants, right?

Then 4; these are probably~ carnivores

Then 1; when a living thing dies, these guys consume the corpse and return the energy to the ecosystem

Have a great day!

Answer:

Sun

Primary Producers

Primary Consumers

Secondary Consumers

Decomposers

Explanation:

Energy coming from the sun is converted into chemical energy (or glucose) by plants. Primary consumers (herbivores) eat those plants and gain the energy they produced. Secondary consumers (carnivores probably) eat the primary consumers and gain that energy. Then they die and decomposers (fungi) return their energy into the soil.
