Biology Class Xi Chapter free essay sample

The description of living organisms including human beings began much later in human history. Societies which indulged in anthropocentric view of biology could register limited progress in biological knowledge. Systematic and monumental description of life forms brought in, out of necessity, detailed systems of identification, nomenclature and classification. The biggest spin off of such studies was the recognition of the sharing of similarities among living organisms both horizontally and vertically.That all present day living organisms are related to each other and also to all organisms that ever lived on this earth, was a revelation which humbled man and led to cultural movements for conservation of biodiversity. In the following chapters of this unit, you will get a description, including classification, of animals and plants from a taxonomist’s perspective.

Eating Dsiorders essays

Eating Dsiorders essays Located forty minutes west of Cincinnati is Miami University. Only 16,000 students reside at Miami University, yet we boasts two professional basketball players (Wally Szerbiac and Ron Harper), a top twenty hokey team, two consecutive synchronized ice-skating national championships, and who can forget the second most beautiful girls in the nation (according to playboy magazine). However, what we should be rated for is our percentage of students with eating disorders. Every afternoon one may bear witness to dozens of girls, already abnormally thin, running all over campus. If you visit Miamis recreational center, the amount of girls multiplies. While visiting the recreational center one will see countless girls running on the indoor track while on the endless waiting list to use a treadmill. Once finished these women do grab a bite to eat, a piece of fruit, a fat free yogurt, and, if they feel like pigging out, a salad. And even when students return to their dorm they still cant avoid the disorders. While walking through a female corridor one will find room after room with Billy Blanks on the television and Buns or Abs of Steel at work. Unfortunately it doesnt end with this. In the worst cases you may hear awful noises of girls vomiting coming from the restroom. Is this the picture of college life depicted in movies or recommended to us by our high school counselors? It should, because this is Miami University. Although few admit it, this campus has one of the most distorted views of body image of any college. I interviewed fifty females from my dorm concerning their feelings toward their bodies. 80% revealed that they thought they were fat. When in actuality, only ten percent qualify as clinically overweight. 72% informed me that they exercised 4 or more times a week. When asked why, most responded, to control my weight. 54% take it a step further and limit their food intake in addition to exercising. ...

What does it mean to be free What is Individual Freedom Essay

What does it mean to be free What is Individual Freedom - Essay Example There are some people who feel obliged to take accountability of family members and communal affairs. People should pursue their dreams regardless of what others perceive about it in order to realize full joy in life. Individual autonomy has different meaning to different people. What a person thinks is fine, may be perceived differently by other people. People should pursue their own decency regardless of other people’s opinion. For example, in Bellah (3), Brian believes that personal autonomy is attained when a person is able to accomplish individual dreams. For example, those who want to pursue success in trade, their joy becomes absolute the moment they are able to achieve that vision. Relatives or communal commitment should not hinder a person from achieving his or her life happiness. For example Brian had to put extra effort after he got married in order to sustain his family. He used to burn the midnight oil so that his family could have a decent living. According to hi m, family commitments made him sacrifice his personal independence. However, autonomy means doing what one desires without limitations (Bellah, 167). Without money Brian could not be able to enjoy nice trips or meet successful people in life. However, Brian later came to realize that he could not achieve full joy in life without family affection. Being able to provide for the family and achieve other essential things in life is a great victory. Regardless of the means used to acquire wealth, being able to provide for the family, such as paying school fees for the children and providing magnificent building, amounts to personal independence. With material possessions, people can do what they want at their own will (Bellah, 21). The dilemma occurs when it comes to gauging the level of achievement attained in a particular moment, and in appraising it with previous success or relating to what others have achieved. However, there is no need to contrast your victory with others, but the m ost essential consideration is your ability to achieve what you purposed to achieve in life. People should put effort towards helping their families and the society. The success of the community in which individual comes from also determines their victory (Bellah, 8).This is because, individuals and the society are reliant on each other. A person should contribute towards success of the society. In the same way, the community will also influence individual’s victory in one way or the other. Also, taking care of the family makes the person feel esteemed. Similarly, an individual draws happiness from the family and the society. For example, Joe engaged in activities of the society and his pleasure was in helping the public (Bellah, 54). Those organizations which are interested in satisfying the public will always ensure they give back to the community. They will design community activities and ensure they succeed. People who come from successful families or societies feel conte nted, and such contentment is what makes a person free. However, it is difficult to compare different communities or families to determine which family or society provides better satisfaction than the others. What matters are not comparing oneself with others but to be contented with own situation and work towards improving existing conditions. Those who find fulfillment in their own victory rather than communal tends to be deceitful. They can deprive the community of its resources to enrich themselves (Bellah, 63).
