effects the marine environment in many ways‚ dredging has a big impact on marine eco systems dredging wrecks reefs and destroys the homes for manor many organisms. When this happens the dirt from the bottom dirties the water up and it makes it harder for fish to see and hunt for their food. Artificial reefs are a positive impact humans have on the marine environment. Doing this builds homes for fish and organisms. It has a big impact on the food chain for fish also. Little fish gather around the reefs

INTRODUCTION Since carbon dioxide concentration in the atmosphere is accumulating rapidly because of burning fossil fuel‚ coal‚ oil and natural gas for power generation‚ transportation‚ industrial and domestic uses‚ our earth has been facing global warming‚ sea level rising‚ flooding and other adverse changes which damage to our ecosystem. To address this challenge‚ we need to find out other alternative ways that do not produce carbon dioxide or that reduce the release of enormous amount of carbon dioxide gases

Discuss how theories of human growth and development can help understand human behaviour. Human growth and development is studied and researched with differing perspectives. There are many ways human growth and development can be looked at. Certain disciplines‚ such as‚ biology‚ psychology and sociology all have opposing viewpoints on the subject. The psychological viewpoint concentrates on the different processes of the mind‚ whereas‚ the biological approach is centred on genetics and environmental

"A carbon fiber is a long‚ thin strand of material about 0.005-0.010 mm in diameter and composed mostly of carbon atoms. The carbon atoms are bonded together in microscopic crystals that are more or less aligned parallel to the long axis of the fiber. The crystal alignment makes the fiber incredibly strong for its size. Several thousand carbon fibers are twisted together to form a yarn‚ which may be used by itself or woven into a fabric. The yarn or fabric is combined with epoxy and wound or molded

Carbon-14 Dating: An Invaluable Yardstick in the Chronology of Humans Archaeologists utilize several methods to analyze data from the past. One scientific tool helps to analyze the radioactive decay of chemical elements found in plant and animal remains‚ pottery‚ and even rocks. Radiocarbon dating‚ also known as carbon-14 dating‚ has developed into one of the most important radioisotope dating methods archaeologists employ. This scientific tool‚ first developed by Willard F. Libby in the late

Chapter 5 1. Discuss when you would use discriminant analysis instead of multiple regression analysis. Explain the difference between metric and nonmetric variables. (This is also discussed in Chapter 1.) Chapter 5 100 word minimum In choosing an appropriate analytical technique‚ we sometimes encounter a problem that involves a categorical dependent variable and several metric independent variables. Recall that the single dependent variables in regression are the appropriate statistical techniques

Activated Carbon Activated Carbon is the best general use adsorbent to remove/reduce a lot of organic and some inorganic contaminants found in different liquid and gas products. Activated carbon has the unique ability to adsorb a wide range of compounds from both the liquid and gas phase. This adsorptive feature is responsible for removing contaminants from water and other substances where the adsorbent material is added. Activated Carbon features a highly crystalline form with a wide surface

Introduction Every human in the world has a significant impact on the water cycle‚ as well me. Every day I use resources and have a major impact in into this cycle. We often use resources without thinking much about it. It is simply normal to us‚ that’s enough of these resources are available for the people. Water is just always available for us. In every day that I take a shower‚ take a bath‚ cook with water or just go swimming in a sea I have an important influence on our water cycle. Water which I
