DNA can illustrate that evolution has occurred since in the process of natural selection advantegeous genes or traits have been selected to pass on through generations and further more evolve as long as the species survies and is successful in reproducing.

Describe a characteristic of both an Emperor Penguin and Galapagos Penguin that evolved differently due to their different envir
nevsk [136]

Answer: The size.

Explanation: On the one hand the Emperor Penguin is bigger reaching up to 48 Inches (120cm) of height and 100 Lb in weight, on the other hand the Galápagos Penguin is much smaller. For example a large adult usually goes up to 21 Inches (53cm) and 5 Lb of weight.

This is directly related to the temperature of the environment in which each one develops, because a body exchanges heat in two dimensions through the surface. So, it's easier for a big creature to maintain core temperature stable.

This is really important in environments like the Arctic where temperature goes below zero and the opposite happen in the Equator where there is a tropical weather all the time.

Estas de acuerdo con la aplicación del principio de la física en ecología:¨la energía no desaparece ni se destruye, solo se tran
saveliy_v [14]

Answer:

Esta afirmación es correcta ya que la ley de conservación de la energía es también aplicable a sistemas vivos  

Explanation:

La ley de la conservación de la energía (la cual es la primera ley de la termodinámica) indica que la energía no se puede crear ni se puede destruir, solamente se transforma, de un tipo a otro. La ley de la conservación de la energía es de vital importancia para entender la existencia del mundo natural. En ecología, la energía fluye de un nivel trófico a otro en forma de biomasa, es decir, dentro de la cadena alimentaria. Esta energía no se puede crear ni destruir sino que es almacenada en los organismos, los cuales representan sistemas abiertos que intercambian materia y energía con el medio. Una vez dentro del organismo, una parte de esta energía es transformada (en plantas, por ejemplo, la energía es convertida en enlaces químicos durante la síntesis de carbohidratos), mientras que otra parte de la energía se elimina al exterior (por ejemplo, se disipa en forma de calor), pero la energía no se crea ni se destruye.
