This is possible because when a star dies, it basically expands to its maximum (explodes). Therefore, the materials of the exploded star mix with the primeval hydrogen of the Universe. Later, other stars are formed out of this mixture. Thats also how the sun was formed. :)

Answer:
The best example of environmental influence that would most likely result in natural selection is that a food resource disappears in a pond, and some frogs in a population can eat the remaining food resource, while others cannot.
Explanation:
Among the environmental factors that can influence natural selection at a given time is the availability of food. Natural selection, from the point of view of evolution, is influenced by adverse environmental conditions, being food shortage one of them.
In conditions of food shortage in a pond, as in the example of the frog population, only the most apt will be able to take advantage of nutritional resources, while the less apt will not be able to survive. The ability to survive with little food available becomes an inherited trait that will be passed on to future generations.
In any case, tolerance to adverse conditions becomes adaptation, which translates into survival and reproductive success.
