Advanced Placement (AP)

Answer:

In order to express the results as a percent, divide the nutrient content (which is expressed in ppm) by 10,000. For example, if the reported value for P2O5 is 2,690 ppm, the calculation to convert to percent would be: 2,690 ppm ÷ 10,000 = 0.269%.

Two heads are better than one. Two is company, three is a crowd. These two sentences are... similar in meaning opposite in meani
Andrew [12]

Answer:

Neither the same nor the opposite

Explanation:

<em>Two heads are better than one</em> is an idiom meaning that it's easier to solve a problem or come up with an idea with the help of another person than alone.

<em>Two is company, three is a crowd </em>is an idiom usually associated with a romantic context. It's used to say that a third person should leave when two people (e.g. lovers) want to be together on their own.

So, when we compare these explanations, we can't say that these two sentences mean the same, nor the opposite.

Explain three ways that agriculture has changed mankind's social structure.
Brut [27]

Answer:

Humans were nomads. Their wandering was mainly in search of food and shelter. When they found that certain places had an abundance of food – plant food or animals for hunting, they stayed on. They observed the plants, their growth and when these food sources diminished, they grew plants themselves, from the seeds they collected. This is how agriculture came about.

When humans stopped their nomadic ways and stayed together, it paved the way for formation of the human social structure. Hierarchies were established in due course.
