Chemical Weapons Chemical weapons use the toxic properties of chemical substances rather than their explosive properties to produce physical or physiological effects on an enemy. Although instances of what might be styled as chemical weapons date to antiquity‚ much of the lore of chemical weapons as viewed today has its origins in World War I. During that conflict "gas" (actually an aerosol or vapor) was used effectively on numerous occasions by both sides to alter the outcome of battles. A significant

Civil engineering is not too hard because you have different position‚ different branches. When you start going to school‚ to take 2 or 3 classes for each branch‚ and when you graduate‚ you can tell which one you enjoy the most‚ but basically with that degree‚ you can do so many things. Engineering is very practical‚ and it’s different every day. At the beginning‚ you will learn‚ but after that‚ it’s all about solving problems. Every day‚ you do something different‚ like different problems‚ different

2 Chemical warfare What is Chemical Warfare: To understand chemical warfare you must first understand what a chemical agent is. A United Nations report from 1969 defines chemical warfare agents as " ... chemical substances‚ whether gaseous‚ liquid or solid‚ which might be employed because of their direct toxic effects on man‚ animals and plants ... ". This means basically that any chemical that is used to directly effect and harm a person‚ plant‚ or animal would be an act of chemical warfare

This method changes the genes‚ in which was passed down from the biological parents. These modified test subjects might not become super objects but they sure are wired and fixed different from the rest of the naturally made things. Techniques allows scientist to determine the charac

GENETIC ENGINEERING GENETIC ENGINEERING GENERAL STEPS What is Genetic Engineering? Genetic Engineering = inserting a foreign gene of interest into a host to transcribe and translate a particular protein. Ex. Inserting the human insulin gene into bacteria to mass produce it. General Steps Obtain the gene of interest (ex. insulin gene) Insert the gene into the host (ex. bacteria) Allow the host to multiply and express the foreign gene get your desired protein! Get lots of cells that can
