<u>Answer:</u>

The most appropriate answer option is A. inform her teacher and use a different beaker

<u>Explanation:</u>

According to the safety standards specified to perform experiments in a laboratory, Stacey should inform her teacher and try to use a different beaker if she sees a crack on hers.

This is to ensure maximum safety which in no case should be compromised. Because the beaker still might break in the middle of an experiment, even if it was not leaking before or she covered it with a tape, thus causing harm to her.

Las bacterias están presentes en todos los alimentos ¿Qué ocurrirá con su metabolismo si refrigeramos o congelamos el alimento?
kozerog [31]

Answer:

Si refrigeramos o congelamos el alimento, las bacterias presentes en ellos tendrán un metabolismo más lento, incluso llegando al punto de la muerte por encima de temperaturas a las cuales no les es posible vivir. Es importante mantener la cadena de frío para que las bacterias no tengan lugar a su reproducción.

Explanation:

Las distintas bacterias que pueden estar presentes en los alimentos tienen distintos parámetros que hacen que sea posible su vida y reproducción. En cuanto a la temperatura, es un factor muy importante ya que podemos encontrar bacterias termolábiles o termoresistentes según puedan vivir en las variaciones de temperatura. La mayoría de ellas no resiste temperaturas frías de refrigeramiento o congelamiento, motivo por el cual los alimentos se conservan así. De esta forma reducimos el riesgo de padecer Enfermedades de Transmisión Alimentaria. La cadena de frío por su parte permite que esa temperatura sea constante a lo largo de todo el procesamiento, transporte y disposición de los alimentos.

Write a list of easy starter pets for kids. (yes this is a real question I have an extracurricular class)
mart [117]

Answer:

Any pet that isn't dangerous (ex: snake isn't the best idea) and can be taken care of by a child. So, a fish would be good because it doesn't need to be walked and doesn't need much attention, just to be fed, which the child can do safely. So just make a list of other easy pets like that :)

Explanation:

Hope this helps!
