During the nineteenth century, women in the United States organized and participated in a

large number of reform movement, including movements to reorganize the prison system,

improve education, ban the sale of alcohol, and most, importantly, to free the slaves. Some

women saw similarities in the social status of women and slaves. Women like Elizabeth Cady

Stanton and Lucy Stone were feminists and abolitionists who supported the rights of both

women and blacks. A number of male abolitionists, including William Lloyd Garrison and

Wendell Philips, also supported the rights of women to speak and participate equally with men

in antislavery activities. Probably more than any other movement, abolitionism offered women

previously denied entry into politics. They became involved primarily in order to better their

living conditions and the conditions of others.

When the Civil War ended in 1865, the Fourteenth and Fifteenth Amendments to the

Constitution adopted, in 1868 and 1870 granted citizenship and suffrage to blacks but not to

women. Discouraged but resolved, feminists influenced more and more women to demand the

right to vote. In 1869^6 Wyoming Territory had yielded to demands by feminists, but eastern

states resisted more stubbornly than before. A women's suffrage bill had been presented to every

Congress since 1878 but it continually failed to pass until 1920, when the Nineteenth

Amendment granted women the right to vote.

Polar bear are adapted to life in the polar region, around the North Pole. Their bodies have

special features that work particularly well in the polar seas. For instance, they have sharp and

powerful claws for catching their food, which is mainly seals. In their own environment, they are

excellent hunter; but if they had to live on the birds and squirrels in other places, they would die.

The science that studies the way that different forms of life are adapted to their particular

environment is called ecology.

The first lesson of ecology is that all life in an environment depends on other forms of life.

Polar bears depend on seals, which can live only where they do because they depend on particular

kinds of fish which are found in the Arctic seas.

There are certain important cycles in nature that show plants and animals depend on each

other: for example, the nitrogen cycles. Plants take nitrogen compounds from the soil and turn

them into protein. Animals eat these proteins and return some of them to the soil as waste products

and the rest when they die. Another cycle is the oxygen cycle. When we breathe, we take in

oxygen, and give out carbon dioxide. Plants absorb it to make sugar compounds, and in the

process oxygen is produced and released to the atmosphere.

An ideal ecological system, living things exist in balance. However, particularly where man

interferes, a species may become too successful and abundant, and the balance is destroyed. For

instance, the use of pesticides to kill a particular plan pest may also kill predatory insects and

even birds, and thus other pests are allowed to increase. Therefore, great care is needed in the use

of pesticides.

Through ecology we try to restore the balance in the ecological system, and thus save the

world from devastation.

In total, the plant has need of at least 16 elements, of which the most important are carbon,

hydrogen, oxygen, nitrogen, phosphorus, sulfur, potassium, calcium, and magnesium.

The plant obtains carbon and hydrogen dioxide from the atmosphere; other nutrients are

taken up from the soil. Although the plant contains sodium, iodine, and cobalt, these are

apparently not essential. This is also true of silicon and aluminum

Overall chemical analyses indicate that the total supply of nutrients in soils is usually high

in comparison with the requirements of crop plants. Much of this potential supply, however, is

bound tightly in forms that are not released to crops fast enough to give satisfactory growth.

Because of this, the farmer is interested in measuring the available nutrient supply as contrasted

to the total quantities.
