by the damages of UV-rays has altered skin color and left a lasting effect on the skin. If one examines the effects of the sun on skin color‚ one will notice that those individuals who live the closes to the equator have the darkest pigmentation and those that live further from the equator have lighter pigmentation. All these facts do not explain that any ethnic group is different in their anatomy. As evident as these facts tell us that race is a social construction‚ theses ideas still stain

the moment at the exact center of your life of as you crossed the equator at night in a boat.”(Collins 51) The motif of the passing of time is represented as a simile by comparing the center of your life to an equator. Passing one day of your life or one year may be nothing but all those days and years combined together can create a lifetime. Half of your life can pass by right before your eyes just like passing across the equator can occur at a fraction of a second. Billy Collins in the book

Mendelian inheritance Mendelian inheritance (or Mendelian genetics or Mendelism or Monogenetic inheritance) is a scientific theory of how hereditary characteristics are passed from parent organisms to their offspring; it underlies much of genetics. This theoretical framework was initially derived from the work of Gregor Johann Mendel published in 1865 and 1866 which was re-discovered in 1900; it was initially very controversial. When Mendel’s theories were integrated with the chromosome theory of

solar energy that is being concentrated on the earth. Thus‚ the summer in Ohio is warmer than the winter. In the Northern Hemisphere the vernal equinox‚ spring‚ is on March 20. During the vernal equinox‚ the sun moves across the celestial equator going north. With the tilt of the earth’s axis and the position of the sun the hours of daylight and night are almost equal. The sun moves to the North. On June 22‚ the summer solstice‚ is the longest day of the year. Due to the position of the

What is DNA? DNA‚ or deoxyribonucleic acid‚ is the hereditary material in humans and almost all other organisms. Most DNA is located in the cell nucleus (called nuclear DNA)‚ but a small amount of

and as a result they all shared similar climates. Australia was near the equator so it was hot and dry with infrequent rains. Some parts of Australia were flooded as sea water levels increased because of the absence of polar ice caps. Jurassic period (200-145mya): During this period Australia was drifting south of the equator and had a warm and wet climate which had cooled down as a result of drifting away from the equator and made way for plant life to flourish. The dry plains of the north and
