Ocean acidification occurs when excess carbon dioxide in the atmosphere causes the oceans to become acidic. Burning fossil fuels has led to an increase in carbon dioxide in the atmosphere. This carbon dioxide is then absorbed by the oceans, which lowers the pH of the water. Ocean acidification can kill corals and shellfish. It may also cause marine organisms to reproduce less, which could harm other organisms in the food chain. As a result, there also may be fewer marine organisms for humans to consume. Many years ago there was a beach Called Coast Brigs where many coral and other life lived. A refinery that burned coal was built nearby and over time the water nearby became very acidic. The coral and marine life died because of this but a few miles north on another beach named Greendale the same creatures are surviving just fine. Which area will you see more marine life. Greendale Beach or Coast Brigs?

Answer: Coast Brigs

Regions on the Earth's surface (or in its atmosphere) that are high above mean sea level are referred to as high altitude. High altitude is sometimes defined to begin at 2,400 meters (8,000 ft) above sea level.[5][6][7] At high altitude, atmospheric pressure is lower than that at sea level. This is due to two competing physical effects: gravity, which causes the air to be as close as possible to the ground; and the heat content of the air, which causes the molecules to bounce off each other and expand.[8] There were two villages: Berg village situated at 3000 ft, at the base of the mountain, and Steep village, situated at 8500 feet. People visiting the area always stop in Berg village and feel great, but they feel bad and winded once they get to Steep village. Which village has more people getting sick from altitude sickness?

Answer: Steep

While people have been able to prevent certain viral diseases by vaccinations for many hundreds of years, the development of antiviral drugs to treat viral diseases is a relatively recent development. Antiviral drugs are medications used specifically for treating the symptoms of viral infections. The first antiviral drug was interferon , a substance that is naturally produced by certain immune cells when an infection is detected. Over the past twenty years the development of antiretroviral drugs (also known as antiretroviral therapy, or ART) has increased rapidly. This has been driven by the AIDS epidemic. Two friends had different diseases. Nigel was more prone to viral infections, so one day he got infected with the HIV virus. Manny had contracted some sort of bacterial infection. Which friend received fewer antiretroviral drugs?
