How can atmospheric nitrogen be converted to ammonium ions or nitrate ions?

Agata [3.3K]

Answer: When a plant or animal dies, or an animal voids waste products, the initial form of nitrogen is organic. Bacteria and fungi in the soil produce enzymes that convert the organic nitrogen back into inorganic ammonium ions (NH4 +). Ammonium is converted to nitrite ions (NO2 -) by soil bacteria like Nitrosomonas

Asi todas las células son muy pequeñas. ¿Qué limitaciones físicas y metabólicas determinan el tamaño celular? ¿ A qué problemas

N76 [4]

Answer:

- Limitación física: la relación superficie volumen es baja para un intercambio eficiente de sustancias con el medio

- Limitación metabólica: en principio no existen limitaciones metabólicas

Explanation:

La membrana celular es una estructura fundamental para el funcionamiento celular, ya que de la membrana celular depende el intercambio de nutrientes y desechos por parte de la célula con su entorno (medio extracelular). En células muy grandes la relación entre la superficie cubierta por la membrana y el volumen celular es muy baja, lo cual dificulta el intercambio de compuestos (tanto nutrientes como desechos) con el medio extracelular. Por otro lado, los mecanismos metabólicos en principio no deberían verse afectados por el tamaño celular. Por ejemplo, los perfiles metabólicos de expresión génica son independientes del tamaño celular y están adaptados a diferentes tipos celulares, desde una célula huevo que es proporcionalmente varias veces más grande que un célula diferenciada la cual sin embargo no ha perdido la capacidad de dividirse, un ejemplo de esto son las células cancerosas derivadas de células epidérmicas diferenciadas las cuales poseen la capacidad de dividirse y de proliferar indiscriminadamente.

What conditions are required for a hurricane to form

andrezito [222]

- The storm must be developing over warm water. The water must be at least 80 degrees Fahrenheit. The warm water provides the energy for increased evaporation of water from the ocean surface.

- The warm water must be at least 200 feet deep

<span>- There should be very little wind shear in the area. Wind shear occurs when there is a difference in wind speed and direction over a short distance. Strong wind shear can stop the formation of hurricane eye walls. </span>

MRNA directs the building of proteins through a sequence of

Ad libitum [116K]

Answer:

The mRNA interacts with a specialized complex called a ribosome, which "reads" the sequence of mRNA bases. Each sequence of three bases, called a codon, usually codes for one particular amino acid. (Amino acids are the building blocks of proteins.)

Nicko: After doing calculations we realize the vehicle did not travel nearly as far as our thought it would when it used the gallon of gasoline.

Teacher: What's your opinion about that Nicko?

Nicko: I claims that the energy could not have been destroyed, but cannot determine what happened to all of the energy.

Bob: It's my turn

Teacher: Nicko, you can go home now.

Nicko: Thank you teacher!
