Answer:
Hay infusion refers to an amalgamation that can be formed by taking samples from different sources like rivers, lakes, ponds, and others. It is one of the best procedures that can elevate the density of the bacteria cell at any specific time interval.
In the given case, even after boiling hay infusion for one hour, growth was observed in the flask after one day. It can be due to certain factors like the hay infusion may have been comprising some endospore, which is resistant to heat or may comprise some kinds of bacteria that can withstand high temperatures.
Because of which, even after heating the infusion for one hour, it did not get influenced by the heat and got the chance to grow when it got optimum temperature again at the time when the sample was left as such.
'Red shift' is a key concept for astronomers. The term can be understood literally - the wavelength of the light is stretched, so the light is seen as 'shifted' towards the red part of the spectrum.
Hope this helps.

Answer:
No, se debe a la capacidad de evolucion genetica que tengan los seres vivos frente a los cambios amientales.
Explanation:
Algunos animales frente a cambios ambientales buscan desarrollar mutaciones geneticas que le confieran una cualidad fenotipica que los beneficie en ese medio, es decir como por ejemplo: picos mas largos, plumajes de diferentes cualidades, patas o dedos mas cortos, etc.
Si esta modificacion genetica es capaz de transmitirse a travez de los progenitores de la especie entonces se puede deducir que la especie evoluciono, por ende tiene una adaptacion exitosa y no depende de sus celulas sino del codigo genetico que estas contengan y si son capaces de transmitir dichos genes para poder asi heredar otras generaciones las cualidades fenotipicas ideales.
