The African Americans in the roaring 20s were treated unfairly and badly. Slavery was a problem in the 20s and African Americans were kicked out of their homes and lost jobs. Many African Americans worked on plantations and were living in harsh conditions. Immigrants also worked on plantations and were refused many jobs due to their background. Many immigrants had a hard time finding jobs and being able to support their family. The stock market crash made it harder for immigrants and African Americans to live. More people were kicked out of their homes due to the stock market crash and many people lost their lives because they were poor and did not have the funds to support their families.

b. This is in the attachment
c. From the calculated opportunity costs, India has been shown to have the comparative advantage in peanuts so they have to specialize here.
The US on the other hand has to specialize in pecans because they have the comparative advantage in it.
d) The PPC for each country is a diagram

Answer:
b) the effects of local evolution or migration on an exosystem
Explanation:
a) false; symbiosis is the relationship between two species with either a mutual benefit to both creatures, one benefiting and the other remaining neutral, or one being negatively affected while the other benefits. There is no relationship between the two groups of blackcaps to a is false.
b) true; the effects of local evolution or migration on an ecosystem. Local evolution has not occured yet but migration has. The effect that scientists believe may happen to the ecosystem because of the migration is the creation of a new species, which would definitely effect an ecosystem
c) false; biotic factors are the living parts of an environment, such as plants, animals, and insects. The difference in the two groups of blackcaps isn't what biotic factors they use but when their mating season is. Biotic factors have no effect whatsover.
d) false; there are no given alterations in the ecosystem. Migration patterns do not just change because of something as small as a shift in bug population. Migration habits are largely genetic, such as is the case of monarch butterflys migrating from north to south and back across the continent. If a group of blackcaps are migrating somewhere different, it has been ocurring for a while, so it isn't fault of the ecosystem that suddenly made blackcaps switch migration course.

Soil salinity can be reversed, but it takes time and is expensive. Solutions include improving the efficiency of irrigation channels, capturing and treating salty drainage water, setting up desalting plants, and increasing the amount of water that gets into aquifers. Mulches to save water can also be applied to crops.
