Coral Bleaching Coral Reefs
1,512 wordsImagine yourself observing one of the most diverse ecosystems on earth. Thousands of species of plants and animals provide a dizzying array of color and motion. Massive structures provide a canopy that shelters hundreds of exotic species in a myriad of microclimate's. As land-based observers, we almost automatically assume that this is a description of the rich ecosystem of a tropical rainforest. However, if we take ourselves off the safety of dry land and immerse ourselves in the ocean, we will...

Flannery O Connor Rises Must Converge
1,525 wordsThe Symbiotic Relationship of Violence and Grace Extending reality outward until it embraced religious mystery, says Gilbert H. Muller (56), is something that Flannery O Connor did with extraordinary finesse. The mystery of grace captivated her and she used violence to shock both her characters and readers into making a decision about grace. O Connor used violence to illustrate the pointlessness of a purely secular world and the indispensable need of God to correct the absurdity of man s conditi...

Amino Acids Fatty Acids
807 wordsToday, weve realised that the very first life on Earth was indeed originated from abiotic surroundings. In fact, organic molecules have been successfully generated from abiotic elements by scientists To understand how this creation of life from abiotic material occured, we have to consider a critical idea. Life originated from its abiotic surroundings. Thus, it is important for us to learn about the physical and chemical environments of the primitive Earth. The atmosphere of primitive Earth cons...

Billion Years Ago 5 Billion
503 wordsHow Changes In The Atmosphere, Eukarotes, And How Changes In The Atmosphere, Eukarotes, And Multicellularity Have Occured And Influenced Life On Earth About 2. 5 billion years ago, oxygen began slowly to accumulate in the atmosphere, as a result of the photosynthetic activity of the cyanobacteria. Those prokaryotes that were able to use oxygen in ATP production gained a strong advantage, and so they began to prosper and increase. Some of these cells may have evolved into modern forms of aerobic ...

Life On Earth Newly Discovered
881 wordsUntil recently, scientists believed that the sole source of energy responsible for life on earth was the sun. In 1977, a group of scientists researching the theory of plate tectonics, traveled to the floor of the equatorial Pacific Ocean and discovered something that could possibly explain how life began on this planet. From the Galapagos Rifts thermal springs, scientists discovered densely populated communities of several species never before observed. Since that time the Federal Government has...
