Learning evolution huh? Good question there. Natural selection alters the gene frequency in a gene pool, changing the population.
Natural selection tends to promote adaptation by maintaining favorable adaptations in a constant environment (stabilizing selection) or improving adaptation in a direction appropriate to environmental changes (directional selection).

Yahoo natural selection question
Answer:
systems help identify parts and simplify solutions.
Explanation:
Systems are very important in science because they are made up of many parts and can help simplify solutions better.
A system is made up of several parts that are interacting together as a whole. They are very important in solving scientific problems and looking introspectively into a problem.
The parts that makes up the system are equally important as the whole. Systems are typified by what transpires at the level of their parts. Viewing a problem from a system wide angle helps scientists have better knowledge and can be vital in solving scientific problems.
