atmosphere of Earth is a layer of gases surrounding the planet Earth that is retained by Earth’s gravity. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation. A. Nitrogen - 78% - Dilutes oxygen and prevents rapid burning at the earth’s surface. Living things need it to make proteins. Nitrogen cannot be used directly from the air. The Nitrogen Cycle is nature’s way of supplying the needed nitrogen for living things. B. Oxygen - 21% - Used by all living things. Essential

Apartheid was bad for non-whites because they had passbooks‚ most families had a lot of separation‚ and non-white people’s salaries were lowered a lot‚ which led to people’s resources being limited. There was so much suffering and most whites didn’t even care‚ they wanted them to be treated even worse. These people knew how it felt like and soon you will too. Black South Africans were held in a form of imprisonment and could do little to fight back‚ causing Apartheid to be one of the darkest periods

Araby Even under the best of circumstances the transition from childhood into adulthood is a long and dreary journey that all young men must encounter in life. A road that involves many hardships and sacrifices along the way; and when that road is a lonely one‚ with only oneself to rely upon‚ the hardship intensifies to become destructive to those involved. This is particularly true in the story "Araby‚" where James Joyce portrays the trials and tribulations of a young boy’s initiation into adulthood

Apocalypto My favorite part of the movie Apocalypto is when Jaguar Paw stops being afraid and beings to fight back. I believe he realized that the Aztec’s wouldn’t have stopped chasing him‚ until he was dead. Also he wouldn’t have fulfilled his name jaguars are strong and brave‚ and they never show any fear‚ also he wouldn’t have made his father proud of him. So he began to take them out by getting poison from poisons frogs with a stick and shooting it at them. Another thing he did was set a

1. How do you define the concept of attention? • Attention occurs when a person is mentally focused on someone or something and channels other distractions out. In my opinion‚ a person pays attention by active listening and intensively observing. For instance‚ a couple on a date in a crowded restaurant gives one another their attention by keeping eye contact and actively listening to everything one another says. I believe it is imperative to show someone you are giving him or her undivided attention

Alcohol and heavy drinking throughout Canada plays a distinctive role in instigating other key addictions. Drinking and consumption abuse can be linked strongly to the abuse of illicit drugs. Binge drinking should be seen as a gateway or portal to the development of poly-drug users. As the gateway drug theory suggests‚ routine use of less harmful drugs‚ in this case alcohol‚ will lead to risk of abusing more serious drugs. Alcohol is so readily available and like any other psychoactive drug it can

Writing:topic 1 Athletes behavior 21/1/10 No one can deny that most people admire athletes for their achievements at sports or their skills. Many famous athletes are considered as bad-tempered while they were not at the beginning of their career. It seems clear to me that the most basic reason for this change in their character is money and sudden fame. A young person usually starts a sport as a hobby or because he wants to escape from the daily routine and his problems. When he or his
