Abird that preys on moths is introduced to the habitat with moths and trees like the one shown above.
what will most likely happen to the population of moths in this habitat?
a. the population of moths will eventually become extinct.
b. the moths will evolve due to a selective pressure.
c. the dark colored moths will experience disruptive selection.
d. the alleles that determine light and dark colors in moths will equalize.

When a bird that preys on the moths is introduced into a habitat that contain two types of moths (dark-colored and light-colored) and light tree barks, the population of the dark-colored moths will decrease rapidly as they will experience disruptive selection. The dark-colored moths will be easier to spot on the light-colored tree barks. Disruptive selection can be defined as the natural selection in which the highly adapted organisms are selected over the average ones.

Hence, the correct answer is 'option C - the dark colored moths will experience disruptive selection'.

americans began to notice growing differences between the northern and southern sections of the country. there were more people living in cities in the north, which made it more urban. more people lived on farms in the south, which made it more rural. while many people were farmers in the northern states, there were now other ways to make a living, such as working in mechanical cotton gins factories manufacturing cloth, tools and other goods. people in the north supported high tariffs on goods imported from europe because the extra cost encouraged people to “buy american” instead. in the southern states, planters did not like tariffs because they sold most of their production to europe and bought their tools from there as well. southerners believed the protective tariff was something that only northern factory owners keep their profits high. so the southern politicians came up with an idea. they would opt out. they would simply ignore the protective tariff. it was ‘null and void’ in south carolina. the state would not collect the taxes on goods imported into south carolina, no matter what the president said they had to do. this decision led to the nullification crisis.
