They expect the Universe to continue expanding. Right now, the evidence is that the expansion is speeding up. They also expect entropy to continue increasing, so in the distant future, there will not be any free energy left to support life, for example.
Im sorry really dont know the answer
<span> Son organismos que pertenecen al Nivel de Organización Protoplasmático. Son UNICELULARES y se distinguen por no poseer un Núcleo bien organizado. Son PROCARIOTAS porque el material genético (ADN o Cromosomas) al no tener Carioteca o Membrana Nuclear, se encuentran dispersos en el Citoplasma. Comprenden a las Cianofíceas y Bacterias. Las Cianofíceas o Algas verde azuladas son Autótrofos, ya que realizan la Fotosíntesis y algunas Bacterias se nutren por Absorción, ya sea descomponiendo a sustratos orgánicos como las Saprófitas, o infectando a un organismo vivo y viviendo a expensas de él como las Parásitas y otras son Heterótrofas y Autótrofas. Poseen un Sistema de Nutrición AUTÓTROFA, HETERÓTROFA y por ABSORCIÓN. Las Bacterias son Células muy pequeñas, que tienen Reproducción Asexual por Fisión Binaria. Tienen Pared Celular porosa. Presentan diferentes Formas (Cocos, Bacilos, Espirilos, Vibriones). Producen Enfermedades (Tuberculosis, Lepra, Sífilis, Neumonia, etc.) Hay Bacterias Beneficiosas (Producción de alcohol y vinagre, quesos, yogurth, etc.). Las CIANOBACTERIAS poseen CLOROFILA y un Pigmento azul llamado FICOCIANINA. Pueden estar libres o en colonias. </span>
Answer:
It is the minimum amount of analyte that produces a signal which can be measured with reasonable accuracy - LOQ
The concentration is equal to three times the standard deviation of the signal from the blank divided by the slope of the calibration curve - LOD
The concentration is equal to 10 times the standard deviation of the signal from the blank divided by the slope of the calibration curve - LOQ
It is the minimum amount of analyte that produces a signal that is significantly different from the blank - LOD
Explanation:
We define the limit of detection has the lowest amount of analyte that produces a signal that is significantly different from a blank solution ( the absence of the substance). It is calculated as three times the standard deviation of the signal from the blank divided by the slope of the calibration curve.
The limit of quantitation (LOQ) is defined as the minimum amount of analyte that produces a signal which can be measured with reasonable accuracy. It is measured as 10 times the standard deviation of the signal from the blank divided by the slope of the calibration curve.
A conversion factor is a ratio (or fraction) which represents the relationship between two different units :)
