If the original length and width are x and y, the original area is xy. If each was reduced by 20%, you would have .8x and .8y , multiply those and the area is .64xy, which means that the area is reduced by 36%

PLZ HELP as a result of the change in the migratory pattern, the two groups of blackcaps(those that migrate to England vs those
9966 [12]

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.

Ipatiy [6.2K]

The claim of the author in "Why public libraries matter is to call the attention of the government to the fact that public libraries should be funded.

<h3>How to depict the information?</h3>

Would you usually expect GDP as measured by what is demanded to be greater than GDP measured by what is supplied, or the reverse
Akimi4 [234]

The correct answer is - GDP by what is supplied.

The best way to measure a GDP is by what is supplied on the market. Basically this means that the GDP should be measured by what and how much the economy is producing. The produced goods and services may be only for the country's market, or also for export, but those are the ones that bring in the money in the economy.

If the GDP was measured by what is demanded than we will have a very unrealistic picture. The reason is that the demand for numerous things can be there on the market, bu the financial power of the people may not actually correspond with it, nor the strength of the economy. A perfect example for something like this is Greece.
