Pond Water Paper DIRECTIONS STYLE TENSE: In all sections of the paper‚ present tense should be used to report background that is already established. For example‚ "The cell membrane is the barrier which separates the inside of the cell from the outside." Use future tense for work that you will do. For example‚ "This experiment will test the hypothesis that some anti-microbial agents can permeate the cell membrane during division to inhibit growth." Use past tense to describe the methods (what

Stratosphere Space Shuttle Endeavour appears to straddle the stratosphere and mesosphere in this photo. "The orange layer is the troposphere‚ where all of the weather and clouds which we typically watch and experience are generated and contained. This orange layer gives way to the whitish Stratosphere and then into the Mesosphere."[1] Atmosphere diagram showing stratosphere. The layers are to scale: from Earth’s surface to the top of the stratosphere (50km) is just under 1% of Earth’s radius

While it has been controversial and subject to much debate (well maybe not that much debate) in the political sphere‚ global warming is a phenomenon that 97% of scientists believe is derived primarily from human activity. Many choose to sweep the rising global temperature under the rug because they don’t foresee the negative effects it could have on humankind if it persists at the same rate. However‚ with increases in atmospheric heat‚ the Arabian/Persian Gulf was inflicted with coral bleaching (caused

SALT WATER Introduction: Salt water refers to water that contains dissolved salts‚ known as saline water or seawater‚ water from oceans or seas. It is a home to varieties of aquatic animals‚ for example‚ fishes and snails. Some of these animals find it difficult to live in fresh water. If salt water animals go to live in fresh water they can not adapt the environment led to die to them. This essay aims to discuss the importance of salt water and the sub- types namely ocean‚ sea‚ and coral reefs

Natural Resources and Energy in the Rainforests The beauty‚ majesty‚ and timelessness of a primary rainforest is indescribable. It is impossible to capture on film‚ to describe in words‚ or to explain to those who have never had the awe-inspiring experience of standing in the heart of a primary rainforest. Rainforests have evolved over millions of years to turn into the incredibly complex environments they are today. Rainforests represent a store of living and breathing renewable natural resources
