I will be showing you how Cheetahs have been negatively affected by Human activity. Throughout time Cheetahs have had many impacts on the world. It has impacted the ecosystem‚ for example Cheetahs feed all types of other animals like‚ beatles‚ vultures and other scavengers. The Cheetah leaves the remaining of the carcass so it

Carbon is the fourth most abundant element found on Earth‚ and is essential to all life as we know it. It is found in all living substances‚ and is essentially the key element for life. Because the carbon atom has the ability to form bonds with up to four other atoms‚ it can help form solid minerals (such “ limestone)‚ ‘squishy’ organisms (such as plants and animals)‚ and it can be dissolved in water. Carbon is also present in rocks‚ dissolved in rivers‚ lakes and oceans‚ and is in the atmosphere

Considerable evidence exists that most of this warming has been caused by human activities... that’s to say we have altered the chemical composition of the atmosphere through a buildup of greenhouse gases – primarily carbon dioxide‚ methane‚ and nitrous oxide. this is what the carbon footprints calls for CARBON FOOTPRINTS A carbon footprint is a measure of the impact our activities have on the environment‚ and in particular climate change. It relates to the amount of

THE IMPACTS OF HUMAN TRAFFICKING THAT AFFECT ETHNIC RELATION Firstly‚ the worst impact is on the health of the human trafficking victim. This is happened when the trafficked person are mostly women and children that are sexually exploited‚ abused or force into prostitution (Pokharna‚ 2011). The victims are usually transported from one country to the other country and this risky journey expose trafficked victims to injury and even death‚ while overcrowded‚ unsanitary conditions‚ shortages of food

The increasing population within the world has had an impact on the lithosphere and consequently as led to the deterioration of this essential component of the biophysical environment. Land degradation has become one of the primary issues of concern arising from the human interaction with the lithosphere. It encompasses soil degradation and the deterioration of natural landscapes and vegetation. It includes

Unsaturated organic compounds : Organic compounds in which a double or a triple bond exists between two carbon atoms in a carbon chain‚ are called unsaturated organic compounds. 10. Hydrocarbons : Organic compounds which contain only carbon and hydrogen atoms are called hydrocarbons. 11. Straight chain hydrocarbons : Hydrocarbons‚ in which all the carbon atoms are linked to one another in a straight chain

Yet it is the one thing we think about the least but we have a huge impact on it. We waster lots of water every day and let nasty chemical get into the rivers and streams from which we get our water.

zero (-459 degrees Fahrenheit‚ 0 degrees Kelvin‚ -273 degrees Celsius) to liquid nitrogen temperatures (-321 F‚ 77 K‚ -196 C)‚ they have no electrical resistance. The temperature at which electrical resistance is zero is called the critical temperature (Tc) and varies with the individual material. For practical purposes‚ critical temperatures are achieved by cooling materials with either liquid helium or liquid nitrogen. The following table shows the critical temperatures of various superconductors:
