A population of pigs lives on an island together with burrowing termites. Pigs that have the longest snouts tend to survive better. Over time, most of the pig population is made up of individuals that have very long snouts. This is an example of which type of selection?
a directional selection

Directional selection

Explanation:

According to the theory of the evolution, natural selection is the mechanism of evolution that is nature selects the trait which increases the survival rate of the organisms.

The natural selection takes place at the level of population and population can be selected in one of the three-ways: directional, stabilising and the disruptive selection.

In the given question, the pigs with the longest snout are favoured which could help them eat the termites and increase the survival rate. This is an example of the directional selection as the extreme phenotype of the snout is favoured over the other phenotype and the population with long snouts are selected by nature to increase the survival rate.

Thus, Directional selection is correct.

mientras se trata la anorexia o la bulimia, es importante buscar ayuda antes que nada. un profesional de la salud mental será el más útil para aquellos que sufren anorexia o bulimia. este es un buen lugar para comenzar, sin embargo, ver a otros profesionales como dietistas registrados, especialistas médicos y dentistas podría ayudar a alguien a recuperarse de un trastorno alimentario. después de la ayuda profesional, o si la ayuda profesional no es una opción, alguien que se recupere de la anorexia o la bulimia debe rodearse de compañeros de apoyo, padres u otros miembros de la familia que también estén comprometidos con el proceso de recuperación.

hope this you! : )
