Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations. Charles Darwin popularised the term "natural selection", contrasting it with artificial selection, which in his view is intentional, whereas natural selection is not.

nika2105 [10]

Answer:

Group 4

Explanation:

The control group in this case would be those students in group 4.

<u>The control group during an experiment is a group that does not receive the treatment administered to other groups and as such used as a standard for measuring the effects of the treatment on other groups. </u>Whatever differences that exist between the control group and the various treatment groups is attributed to be as a result of the treatment administered to the groups.

Usualmente la recesiones provocan
Over [174]

Answer:

La recesión provoca un aumento en el gasto público del gobierno para hacer que la economía flote hasta que haya estabilidad. Esta es una característica común en la economía y, como tal, ayuda a amortiguar el efecto de una recesión. Se perderán muchos empleos, aumentando así los niveles de desempleo. Por lo tanto, el gobierno tiene que gastar más para ayudar a los afectados a sobrevivir.

Explanation:

Una alta tasa de desempleo y las malas condiciones económicas llevan al gobierno a un mayor gasto durante el tiempo de recesión. El propósito es ayudar a estimular la economía y ayudarla a sobrevivir las dificultades económicas. Un ejemplo típico es el paquete de estímulo de Obama en los Estados Unidos de América en 2009 en respuesta a la gran recesión.
