medicines is a long and costly process. It usually takes up to 12 years and costs more than $200 million. 1. First the drug must be isolated or synthetized. 2. The drug is tested on animals. LD50 and ED50 are determined. 3. The drug moves to Clinical Trials a. Human Pharmacology – testing on small group of healthy volunteers for safety b. Therapeutic Exploratory – evaluates drug’s efficiency and side effects c. Confirmatory Stage – large-scale testing of drug 4. A

Evaluate the strategies used to reduce the impact of tectonic hazards. Tectonic hazards are comprised of earthquakes and volcanoes; they are named ‘tectonic hazards’ as it is ultimately the movement of tectonic plates that cause these events. These hazards have the potential to kill thousands and devastate the region it strikes. Although the main hazard causes destruction‚ events that follow can be equally‚ if not more‚ devastating‚ for example an earthquake can often trigger a tsunami. Many strategies

The San Andreas Fault and its role in Plate Tectonics and Earthquake Prediction The San Andreas Fault is one of the most widely studied faults in the world. Scientists use an array of methods in collecting data and providing analysis of fault characteristics both past and present. Presently there are many differing hypothesis and models used to describe crustal movements and deformation within the Pacific and North American plate boundary. Historical earthquakes along this fault have proven to be

Structure of the Earth and Plate Tectonics Structure of the Earth Mantle • The Earth is made up of 3 main layers: Outer core Inner core – Core – Mantle – Crust Crust The Crust • This is where we live! • The Earth’s crust is made of: Continental Crust Oceanic Crust - thick (10-70km) - buoyant (less dense than oceanic crust) - mostly old - thin (~7 km) - dense (sinks under continental crust) - young How do we know what the Earth is made of? • Geophysical surveys: seismic‚ gravity‚ magnetics‚

“Volcanic and seismic events are major pieces of evidence towards proving that the plate tectonics theory is valid” Discuss the extent to which you agree with this statement (40m) The theory of plate tectonics explains the structure and motion of the Earth’s lithosphere. The theory states that the Earth’s crust is split into large sections called tectonic plates‚ and these move relative to one another creating boundaries at which the plates converge‚ diverge or move past each other. These plates

Melanie Brooke Yeakley 1. What is the myth from which volcanoes get their name? •It comes from the little island of Vulcano in the Mediterranean Sea off Sicily. Centuries ago‚ the people living in this area believed that Vulcano was the chimney of the forge of Vulcan--the blacksmith of the Roman gods. They thought that the hot lava fragments and clouds of dust erupting from Vulcano came from Vulcan’s forge as he beat out thunderbolts for Jupiter‚ king of the gods‚ and weapons for Mars‚ the god

What is Volcanic Eruption? A volcano can be simply defined as a rupture or an opening on the crust of a planet like earth. This opening allows hot ash‚ molten rock and gases to blow off from the underground spaces. Volcanoes generally acquire shape of a mountain. Volcanoes are usually found at places where tectonic plates get converged or diverged. But there existence at a particular place depends upon many environmental and geological factors. Volcanoes can also occur at a place because of

Abstract Energy is an important part of our everyday lives. Energy can come in many different types‚ and forms it can be used for many different purposes. Energy has many different usages and can be converted from one form of usage to another form of usage depending on what the need is. One form of energy conversion is the use of food to supply people’s bodies with energy. Another form of energy is how coal is converted into electricity. Fuel is another form of energy that can be used
