A bird that preys on moths is introduced to the habitat with moths and trees like the ones shown below.

A white moth and a black moth are shown.

What will most likely happen to the population of moths in this habitat?
The population of moths will eventually become extinct.
The population of light moths will increase due to a selective pressure.
The dark colored moths will experience disruptive selection.
The alleles that determine light and dark color in moths will equalize.

C. The dark colored moths will experience disruptive selection.

Explanation:

When A bird species is introduced in the habitat with white and black moth, the moths in black or dark color will experience disruptive selection as The tree or habitat is favoring white moth and black moth will be easily noticed by predators or birds.

Disruptive selection is a type of natural selection in which genetics of population is changes by favoring traits with extreme over intermediate values.

Due to increase in pressure of predators the dark moth will try to find the  advantages from light shoot trees (as shown in figure) for survival and leads to speciation with two or more different species forming, and the moth with middle traits will be wiped out.

Hence, the correct option is C.

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.

the question isn't complete here so i can't right an answer '_'
