Rate Of Reaction Bunsen Burner
1,230 wordsInvestigate A Factor Which Affects the Rate Of Fermentation Of Yeast This experiment is investigating one of the factors which affects the rate of fermentation of yeast. Several factors affect the rate of reaction: &# 61656; Increasing the concentration. (See the lock and key theory. ) If the substrate (glucose) is increased, then there would be more keys for the locks, therefore an increase in reactant concentration leads to an increase in reaction rate. &# 61656; The surface area, the bigger t...

Rate Of Reaction Carbon Dioxide
1,229 words... onward sources, from a textbook, encyclopedia, and preliminary work that I have done in class. I have shown my results on a bar chart and a line graph. On the line graph, I have drawn a curve of best-fit. There were no anomalous results. From my results, and my graph, I have found out that as the temperature of the enzymes (yeast in this case) is increased, the rate of reaction speeds up. However, when the temperature reached a certain point, (about 40 degrees Celsius), the enzymes became de...

Invasion Of Molesta Kariba Weed
1,104 words... the traditional transplanted method to direct seeding method was taking place particularly at Must rice granary area. The increased usage of fertilizers resulted in the leaching of a certain amount of nutrients into the aquatic ecosystems. A fertilizer that is generally rich in phosphate and nitrate plays an important role in triggering the tremendous growth of floating weeds (Caffrey et. al 1996). A noticeable feature of rice fields that depend heavily on the use of fertilizer is the occurr...

Greenhouse Gas Emissions Problem Of Global Warming
1,385 wordsHow can the nations of the world work together multilaterally to successfully address the problem of global warming? The numbers are striking. No region of the world will be unaffected if Global Warming continues to increasingly grow. Yet day after day people take actions that can change the earth and its climate in significant ways. Many people just stand motionless as the wave of climate change becomes more apparent. The IPCC predicts that during the next century, the average rate of warming w...

2,167 wordsAlternative Fuel Vehicles You Can Buy Today From the earliest days of the automotive industry alternative fuels have always competed with petroleum for powering vehicles. Nicholas Cugnot made the first self-powered road vehicle in 1769 with a steam engine, and the first gasoline automobile didn't appear until over 100 years later from Karl Benz. Through the late 19 th and early 20 th century steam and electric power remained strong contenders. The invention of the self-starter for gasoline engin...

Degrees Celsius Atomic Mass
318 wordsAn American Chemist named Glenn T. Seaborg discovered plutonium in 1941 at Berkeley University in California. The discovery of Plutonium was not announced until 1946 because America was at war with Japan and Germany. Plutonium was named after the planet Pluto, after the planet Neptune in the solar system and Neptune gave its name to Neptunium. Plutonium is a silvery metal that turns yellow when exposed to air. It is warm to the touch due to the releasing radioactive energy from it. The atomic nu...

Food And Shelter Coral Reefs
682 wordsCorals and Adaptations Coral reefs are among the most diverse and productive communities on Earth. They are found in the warm, clear, shallow waters of tropical oceans worldwide. Reefs have functions ranging from providing food and shelter to fish and invertebrates, to protecting the shore from erosion. Although many corals resemble plants, they are actually members of the animal phylum Cnidaria. Most corals are colonial, which means that each coral is made up of many individual polyps connected...

Earth Surface Stop Global Warming
980 wordsIn the last century, the earth? s surface temperature has increased 0. 45 - 0. 60 degrees celsius. Although some scientists believe global warming is not a problem, many scientists believe that global warming is a serious problem, and can not be ignored. Global warming, as the term implies, is the increasing temperature of earth. A factor that is believed to play a part in this is the greenhouse effect, which is the effect in which greenhouse gasses, such as carbon dioxide allow incoming solar r...

Thermo Regulating Indoor Cabinets Plants
598 wordsIt is hard to believe that some plants produce as much heat for their weight as birds do, which are the greatest heat producers of all. It is even harder to believe that some are able to thermo regulate, which means that they actually alter their heat production to keep their temperature constant in fluctuating air temperatures. This is similar to what mammals do. The article I am reviewing tells about few a plants that do this, and how they do it. There are only three plants which have yet been...
