A population of mosquitoes has an average wingspan of 6.5 mm. Following an especially wet summer, the local bird community experiences a population surge, resulting in more mosquito predators. Small size enables greater chances of survival facing these predators. As a result, the next year, the average wingspan of the mosquito population is 4.1 mm. This is an example of:

c. directional selection.

Explanation:

Directional selection is considered a force in nature that allows for a specie to evolve towards one end of a trait spectrum. When that happens overtime, the selected traits (shorter wingspan of 4.1mm) will be permanently more than the traits opposed (longer wingspan of 6.5mm).

idk but found this on google

"the kansas-nebraska act allowed each territory to decide the issue of slavery on the basis of popular sovereignty. kansas with slavery would violate the missouri compromise, which had kept the union from falling apart for the last thirty-four years. the missouri compromise had prevented this from happening since 1820."

overview:

this is a technology-dependent lesson that students can guide at their own pace of exploration and learning. students share what they learn through the use of twitter (or alternative classroom sharing medium like todaysmeet). the use of a social sharing platform like twitter gives students a place for sharing with a wider audience, for more effective means of communication with each other, for incorporating viewpoints from all students in the classroom, and a means to reference thinking and learning by the use of a hashtag at a later time. students will understand the role the allied air forces played in the normandy invasion. teachers can use this as a stand-alone lesson or offer more structure by guiding students through each source, one by one. teachers may learn more about the eighth air force by accessing the abmc’s strategic bombing campaign interactive.
