The ozone layer has begun to become 'thin.' It is often referred to as the 'hole in the ozone layer.' This problem has been created by human activities and specific chemicals that have been released.
The chemicals released into the atmosphere are known as CFC's. ...
The latest technological developments in the field of bio engineering has allowed specialist to proceed with the successful cloning of organisms. Bioengineering has certainly opened doors to science that people have never considered before but this has also come with attached controversy. There are many ethical issues of cloning that are being disc...

Purpose: In this lab we will observe the products of of potassium perchlorate (KClO4). We will then predict from our results the correct chemical reaction equation. Procedure: 1. Weigh out about 4.0g of KClO4 in a test tube. Record the accurate weight below. Product Weight Before Weight After Mass of Test tube + KClO4 41.5g 39.8g Mass of Test t...
Surface Area to Volume Ratios in Plants (Arid vs. Moist Environments) The ability of plants to survive in certain environments depends on many abiotic factors such as the amount of water or light available. It is important to look at how these factors affect the growth and survival of plants in order to determine their future success. In today's...
Consciousness is understood in a variety of ways. In one belief, a person is conscious when awake, but unconscious when sleeping or comatose. Yet people also do things requiring perception and thought unconsciously even when they are awake. A person can be conscious of their physical surroundings, pain and even a wish or fantasy.

After the recent discovery of single-cell life forms from mars were discovered contained in meteorite that crashed to the earth 12 YEARS AGO. I have many doubts to believe that it is the case. There is still no proof after all these years that the sightings of flying sources moving across the sky at tremendous speeds do really exist in the first pl...
During the nineteenth century, two prominent writers, Herman Mellville and Charles Darwin both voyaged to the Galapagos islands off the coast of Ecuador. Both of these individuals wrote descriptive passages about the physical attributes and atmosphere of the Galapagos Islands. The passages vary in specific content due to the intentions and inter...
According to the American Association of Premature Infants (AAPI), over 400,000 babies are born prematurely or at a low birth weight. As a result of being born early they are more likely to require high-technology intensive and specialized care in the hospital and follow-up care as infants and children. As a result, many have chronic medical proble...
There is currently much debate on the desirability of landfilling particular wastes, the practicability of alternatives such as waste minimisation or pre- treatment, the extent of waste pre-treatment required, and of the most appropriate landfilling strategies for the final residues. This debate is likely to stimulate significant developments in la...
Period 3 Grade 8 is a mineral. it is not a plant or a animal. is a metallic metal. It can never be broken down into differnet substances by normal chemical means. was one of the first metals known to humans. People liked it because in it's native condition, it could easily be beaten into weapons or tools. has been one of the most useful metals...
Salinity in both the rivers and on the land is one of the main and most costly results of overclearing and irrigation. Salinity is caused by changes in the delicate balance between surface water and groundwater systems. A small increase in the infiltration of water from the topsoil to the groundwater, due to rainfall or irrigation, can result in a...
Write an essay on intermolecular bonding. Explain how each type of bond arises and the evidence for the existence of each. Comment on their strengths in relation to the types of atoms involved; the covalent bond and relative to each other. Use the concepts of different types and strengths of intermolecular bonds to explain the following: There exi...
