A population of frogs with
slightly different coloring is an example of microevolution. Microevolution is
the changes in the gene pool of a population that can be measured and observed in
short periods of time within a population. Microevolution can take place in
several ways such as gene flow, genetic drift, mutation and selection.
The ultimate source is mutation.It is the only way that new alleles and genes are created.
La cantidad de agua que se va contaminando es irrenovable y se va almacenando con el tiempo en los océanos, las cantidades de agua se abastecen con el flujo de los nevados pero el cambio climatico hace que este ciclo sea aun más rapido con el derretimiento de los nevados más rapido, aumentando la velocidad del ciclo.
El oceano tambien es afectado, varias cantidades de agua se contaminan con el contacto de estas.

More than 150 years ago, inventors began working on a bright idea that would have a dramatic impact on how we use energy in our homes and offices. This invention changed the way we design buildings, increased the length of the average workday and jumpstarted new businesses. It also led to new energy breakthroughs -- from power plants and electric transmission lines to home appliances and electric motors.
Like all great inventions, the light bulb can’t be credited to one inventor. It was a series of small improvements on the ideas of previous inventors that have led to the light bulbs we use in our homes today.
