Answer:

Los parámetros son: magnitud, extensión, persistencia, reversibilidad, recuperación, persistencia, sinergia, probabilidad de ocurrencia, relación causa y efecto

Explanation:

La evaluación de un impacto ambiental debe tener en cuenta los siguientes parámetros principales:

- Magnitud. La magnitud se refiere al hecho que un impacto ambiental puede afectar al ecosistema en diferentes niveles.

- Extensión. Este término se refiere a la superficie (por ejemplo, en metros cuadrados) del ecosistema el cual ha sufrido el impacto.

-Reversibilidad. La reversibilidad indica la probabilidad de que el ecosistema una vez que ha sufrido el impacto pueda regresar a su estado inicial.

- Recuperación. La recuperación es el grado de restauración al que puede llegar el medioambiente una vez sufrido el impacto.

- Persistencia. La persistencia indica la duración (cuantificable en tiempo) del impacto ambiental.

- Sinergia. La sinergia se refiere al hecho de que dos o más impactos ambientales poseen un efecto mayor sobre el ecosistema que el producido mediante varios impactos ambientales por separado.

- Probabilidad de ocurrencia. La probabilidad de ocurrencia expresa la posibilidad de que un impacto ambiental se produzca en un ecosistema durante un determinado período de tiempo.

- Relación causa y efecto. La relación causa y efecto clasifica a los impactos ambientales en directos (causados por el impacto) e indirectos (causados por las consecuencias derivadas del impacto).

Which enzyme(s) involved in fatty acid synthesis utilize ATP? Select all that apply.

GREYUIT [131]

Answer:

a. Acetyl CoA carboxylase

Explanation:

Much of the fatty acids used by the body is supplied by the diet, excessive amounts of carbohydrates and protein obtained from the diet can be converted to fatty acids and stored as triglycerides. Fatty acid synthesis occurs mainly in the liver and mammary glands, and to a lesser extent in adipose tissue and kidney, the process incorporates acetyl CoA carbons into the forming fatty acid chain using ATP and NADPH.

The acetyl portion of acetyl CoA is transported to cytosol as citrate, produced by condensation of oxaloacetate and acetyl CoA, the first reaction of the citric acid cycle, this occurs when the concentration of mitochondrial citrate is high, observed when there is a high concentration of ATP and isocitrate dehydrogenase is inhibited. The increase of citrate and ATP favors the synthesis of fatty acids, since this pathway needs both. Acetyl CoA should be converted to malonyl CoA. Carboxylation is catalyzed by acetyl CoA carboxylase and requires ATP, this reaction is the regulated step in fatty acid synthesis: it is inactivated by products, malonyl CoA and palmitoyl CoA, and activated by citrate, another regulatory mechanism is reversible phosphorylation of enzyme, which makes it inactive due to the presence of adrenaline / glucagon

Which of the following is the most likely result of converting farmland to urban development? A. People learn to live off less f

goldenfox [79]

The right option is; D. The amount of land available for growing crops decreases.

Urban development involves converting an area to an urban state in different dimensions such as physical, geographical, economic, and societal through population, and land use change. The conversion of farmland to urban development has many effects in terms of food security, reduced agricultural productivity, and agricultural labors. Urban development reduces the amount of land available for growing crops, and can increase food costs in the affected area.
