The Weather
Weather describes the condition of the atmosphere. The condition of the atmosphere may be hot or cold, wet or dry, calm or stormy, clear or cloudy. The layer of gases surrounding the planet Earth is called the Earth's atmosphere. The atmosphere is made up of different gases and acts as a shield protecting life and it also helps maintain a safe temperature on Earth.
The temperature is the degree of hotness or coldness in the air, sometimes called air temperature. A thermometer is the instrument used to measure the temperature of the air or any other substance. The temperature based on the motion of the energy in the air. If the gas molecules in the air move faster, the air temperature will increase.
Humidity is the measurement of water vapor, or the invisible water in the air. Air pressure is the weight of the atmosphere pressing down on the Earth. Air pressure is also called atmospheric pressure. A barometer is used to measure atmospheric or air pressure. It is used by scientists, called meteorologists, who study the weather to forecast changes in the weather.
The change in air pressure has an effect on weather. Air moves from higher pressure to lower pressure, so if there's high and a low nearby, it can be windy as air rushes between the two. High pressure situations are generally associated with fair, sunny weather. Low pressure areas are generally cloudy/rainy areas; strong areas of low pressure bring the stormiest weather.
In higher altitude places, the air pressure decreases because the air is less dense here. However, in lower altitude places, the air pressure increases because the air is denser at lower sea levels.
Wind is caused by air flowing from high pressure areas to low pressure areas. The differences in the pressure is caused by the uneven heating of the Earth's surface by the sun. Some areas of the Earth receive more heat from the sun than other areas. This also results in various wind speeds. A difference between high and low pressure will cause wind, but the greater the difference the stronger the wind.
The rotation of the Earth also has an effect on the direction of the wind. If the Earth did not rotate, the wind would blow in a straight direction. Since the Earth rotates, the wind is deflected from the straight path.
Local winds are created as a result of mountains, vegetation, bodies of water, and other similar natural bodies. This is why local winds may change often, from mild breezes to strong winds in just hours. Local winds cover short distances.
There are several variables that affect the type of weather on the Earth, one is location. Coastal areas may have different weather patterns than mountainous areas. Weather also depends on a place's distance from the equator.
In summary, the Earth's weather can be warm, cold, windy, dry, rainy, snowy, and different combinations of each. Temperature affects air pressure, wind has an effect on temperatures, and there are other variables affecting the type of weather occurring throughout the world.
Factory Life in the 1800's
The Industrial Revolution occurred in the late 1800's. Machines began to take the place of what several humans could do. Many people were employed in factories where items were manufactured. Conditions in these factories were very poor.
Children went to work as early as the age of seven. Wages were very low. Since there was no regulation by any area of government, workplaces were often unsafe and unhealthy. If a worker was injured or died at a factory, the company offered no help to the family. By 1900, deaths in factories amounted to 35,000 a year. Injuries affected 500,000 people. When an incident occurred in one location where a great number of factory workers died, people noticed these poor working conditions.
Women and children were hired to save money for the company. They were paid much less than an adult male would have been paid. Some women even worked in heavy labor as machinists or railroad workers.
The number of working children under the age of sixteen grew to 1.6 million by 1900. They worked long hours for little pay. Some states passed child labor laws which limited the children to working ten hours per day. All companies did not obey these laws. Many children were killed or injured.
Some workers quit these poor factory conditions. Some remained and lowered their rate of production or tried to break the machines. Some began to organize labor unions to fight for better pay and conditions. Many just endured the poor situations. Although thousands joined labor unions in the late 1800's, many workers were still not organized into the 1900's.
Business owners argued that higher wages would bring about higher prices for the consumers. In the 1890's, the government called the unions organizations operating 'in restraint of trade.' The government used the Sherman Antitrust Act against unions instead of against businesses.
Between 1890 and 1920, a period called the Progressive Era, many groups were organized to fight low wages, child labor and long hours for factory workers. Several states passed laws to provide minimum wages for women, do away with child labor, and provide funds for workers hurt on the job. Workers' compensation is the phrase describing financial help for those workers injured at work.
The unions did not want these problems to be handled by laws. They wanted to use the power of the labor unions to bargain with employers. Businesses persuaded unions to accept workers' compensation deals which were not as good as the workers wanted. Businesses did not want to include certain types of workers in the plans. They just wanted to protect themselves from having to pay large sums of money which might be demanded by the courts in case of an injury.
In 1904, the National Child Labor Committee was formed to convince states to pass laws ending the employment of young children. The committee was not effective because states were hesitant to pass laws which were too tough on businesses in case the laws would drive a business to another state which did not have such harsh laws.
In 1912, the Department of Commerce and Labor began a Children's Bureau to investigate 'all matters pertaining to children.' Efforts to pass laws against child Labor continually failed. Finally, Congress passed the Fair Labor Standards Act in 1938.
Thanksgiving
Thanksgiving has a long history, the earliest known records going back to the 16thcentury. Most people don't know that the actual activity of giving thanks while holding a feast is from long before the British came and settled America. The Spanish and the French both conducted thanksgiving at this time, and it wouldn't become a regular activity for British colonies until 1607 in the Commonwealth of Virginia.
The first official town to hold a thanksgiving celebration was Jamestown, Virginia, which held it in 1610. The most famous celebration that most Americans view as the original thanksgiving was the Plymouth Plantation, located in Plymouth, Massachusetts, where the people who lived there had a feast every time they had a good harvest. It would continue as an event of religious purposes in the autumn or early winter, then became a tradition.
There was a Patuxet Native American from the Wampanoag tribe that taught the Pilgrims (early European settlers in Plymouth, Massachusetts) to catch eel as well as grow corn. His name was Squanto, and he learned English while enslaved in England. The leader of his tribe, Massasoit, gave the settlers supplies such as food during their first winter when they had run out.
The Pilgrims of Plymouth would celebrate for three days in 1621 shortly after their first harvest in 1621. While people aren't sure of the precise time, James Baker narrowed it down to between September 21st and November 11th, more likely near Michelmas (September 29th, the Feast of Saint Michaels, Gabriel, Uriel and Raphael). It included 50 people from the Mayflower, as well as 90 Native Americans. All the food was prepared by Pilgrim women, their young daughters, as well their servants.
By 1623, the event was noted by governmental authorities, making it the first 'true' Thanksgiving. Governor Bradford would be the one to officially give praise and notice to the event, and the feast was followed by members of the plantation fasting, and a 14-day rain followed. This rain followed a terrible drought, and Bradford wrote: 'And afterwards the Lord sent them such seasonable showers, with interchange of fair warm weather as, through His blessing, caused a fruitful and liberal harvest, to their no small comfort and rejoicing.'
Thanksgiving under the Continental-Confederation Congress, which governed the United States from 1774 until 1789, would declare several 'national days of prayer, humiliation, and thanksgiving'. This was continued by President George Washington and John Adams, and this would manifest itself into what we know as Thanksgiving in the United States of America today.
It wouldn't be until Abraham Lincoln became President, would a day be chosen for Thanksgiving. He would declare that the last Thursday of November would be a national Thanksgiving, and since 1863 it has been celebrated every year since. It is a staple of the United States now, and encompasses many different events including the feast, giving thanks, prayer, and American football.
Antibodies
A vital ingredient that is a part of every person's immune system is its antibodies. They are large y-shaped proteins, also called immunoglobulins, found in the blood or other body fluids of humans and other vertebrates, animals with backbones. They are the key element in the immune system.
As the immune system works to keep the body healthy, an antibody will recognize unique parts of foreign invaders called antigens. The tip of the 'Y' of an antibody includes a structure that matches one specific key-like structure of an antigen, which binds the two structures together.
The mechanism then tags a microbe or an infected cell for an attack using the other parts of the immune system, or it can neutralize the target directly without assistance. The production of the antibodies is the main function of the immune system.
The body contains a wide variety of antibodies and each one is different, and they are all designed to take only one kind of antigen, which is usually a virus or bacteria. For example, an antibody that targets and destroys an antigen related to smallpox is unable to attack an antigen for the common cold.
The structure of all antibodies is generally the same, the small region of the tips of the protein is extremely variable. This allows millions of antibodies with different tip structures to exist in the body. Each can then bind to a different antigen when necessary. The diversity of the antibodies allows the immune system to recognize the wide variety of antigens it must constantly attack.
A huge variety of different antibodies is made in a single person, the number of genes available to make the proteins is limited by the size of the genome, which is the sum of all the DNA in an organism.
Vertebrates need millions of different antibodies because there are a large number of microbe strains. Humans generate about 10 billion different antibodies and each is capable of binding a distinct antigen site. However, this must be done with a much smaller number of genes, since the total human genome has only about 20,000 genes.
Genetic mechanisms have evolved that are complex, but they allow vertebrate B cells to generate a huge pool of antibodies from a small number of antibody genes. This occurs by combining segments from a pool of genes in many different ways. Hyper-mutations then occur in the binding site area of the antibody gene creating more diversity.
The terms antibodies and immunoglobulin are often used interchangeably and are typically made of basic structural units. They each have two large heavy chains and two small light chains. There are several different types of antibody heavy chains and several different kinds of antibodies. They are grouped together into different isotypes (causes the production of antibodies) based on which heavy chain they possess. There are five different antibody isotypes known in mammals which help direct the appropriate immune response for each different type of foreign object encountered.
The region where variants can bind to a different antigen is known as the hypervariableregion. It is here where the enormous diversity of antibodies allows the immune system to recognize an equally wide variety of antigens. Antibody genes can also reorganize in a process called class switching allowing a single antibody to be used by several different parts of the immune system.
In summary, the immune system helps keep an organism healthy, but it would not be possible without the large number of antibodies that can attack antigens which can lead to a virus or bacteria causing the body to become unhealthy.
