Rom4ik [11]

Answer:

Es probable que a través del tiempo la población de piojos también se vuelva resistente al segundo pijojicida. Los piojos resistentes se generan por un proceso de selección natural  

Explanation:

La evolución es el proceso mediante el cual los organismos cambian (evolucionan) con el tiempo con el fin de adaptarse a sus condiciones ambientales. La selección natural opera seleccionando aquellos individuos mejor adaptados al ambiente en el cual cada individuo se desarrolla. Los individuos adaptativamente superiores poseen más chances de sobrevivir y de reproducirse, trasmitiendo de este modo sus genes a la descendencia. Las mutaciones representan la fuente principal de variabilidad genética en la forma de nuevos alelos y genes. Las mutaciones que son beneficiosas y confieren una ventaja adaptativa son seleccionadas por selección natural. En este caso, la resistencia al primer piojicida se debió a la aparición de una o más mutaciones las cuales confirieron resistencia al primer compuesto. Con el tiempo, la frecuencia de los individuos portadores de mutaciones beneficiosas en la población de piojos fue incrementándose paulatinamente (como resultado del proceso de selección natural). Es muy probable que este proceso evolutivo también se repita con el segundo piojicida.
