  3. Ecosystems: Photosynthesis

    If it is green, then it photosynthesises. Some examples of these types of plants include the beach grass, shrubs, and maritime forest plants found on Plum Island. There is a huge range of plants that can photosynthesise, whether it be microscopic bacteria or extremely large trees. In every ecosystem, there are always active producers that photosynthesise. AIM The aim of this experiment will be to test the rate of photosynthesis using Gardenia Augusta Magnifica in a warmer environment against a cooler environment. HYPOTHESIS The rate of photosynthesis in a warmer environment will be faster than the rate of photosynthesis in a cooler environment.

  5. IB GR4 Project / Global Warming

    Also, if air dries, the minerals precipitate, the water becomes harder. Carbon dioxide, which is dissolved in the ocean water reacts with water carbonic acid. The pH decreases, acidity also acts upon lives of organisms, in the ocean and on land, by the acid rains. The use of coal, oil, and natural gases increases the amount of carbon dioxide present in the Earth's atmosphere. A certain amount of carbon dioxide is needed for especially photosynthesis and plant growth. If there is more carbon dioxide than needed, plants start to loose less water and begin to grow under drier conditions.

  6. Group 4 Chemistry - Amylase

    It is possible to predict as the concentration of salivary amylase is increased we will see an increased rate of reaction as this is constant with all enzymes. We should see an increase in reaction rate as the concentration of the enzyme is increased. However to predict the effect of pH and temperature on the rate of reaction we observe the following: 1. Salivary amylase is found within the mouth, the temperature of the human body is around 37�C. We can therefore predict that the optimum temperature for salivary amylase is around the same temperature and that temperature changes in

  9. Comparing the depiction of Indian women in the paintings of RAJA RAVI VARMA during the colonial period and in the works of FRANCIS NEWTON SOUZA during the postcolonial period

    It is not unusual to say that women have stolen the show in the hands of the painters and the portrayal of women has undergone a massive change with the passage of time. If Ravi Varma?s Sita, Draupadi, Damyanti and Shakuntala are the representatives of the rich legacy of Indian Painting, Jatin Souza?s nude paintings, such as ?the nude Indian woman with mirror? and ?standing nude? are a mirror that shows the transformation of the stereotyped image of the women over the years.

  10. Non-Renewable and Renewable Solutions to Australias Future Electrical Energy Needs

    If this problem is not addressed, millions of Australians will be affected, in addition to businesses, as costs for basic electricity will rise and our methods to extract electricity from non-renewable resources will also affect the environment, as the emission of greenhouse gases will continue to grow. For us to solve the problem of electricity going into the future, we will have to find alternate sourced of electricity that can address the issue involving the diminishment of current non-renewable sources.

  11. Research Report Time management strategies among HKU SPACE Community College students".

    Time management is important should be a true statement, however, from the research, only few respondents suggested that time management was not important.

For those who had planning habit, only 7 interviewees thought that having a plan was very helpful to their daily performance.

  12. Determine the presence of reducing sugar, protein and starch in the food products by using Benedict test, Biuret test and Iodine test,

    Benedict test[2] Benedict test is used to determine the presence of reducing sugar which is monosaccharide and some disaccharides. However, non-reducing sugars such as sucrose won?t have Benedict reaction. In order to have the result with Benedict test, the non-reducing sugars first would have to be transformed into reducing sugars. This can be done by adding hydrochloric acid (HCl) and hydrolyzing them. Here is the purpose of HCl/Benedict test.[3] So basically, Hcl/Benedict test is used for determination of sucrose.

  13. Group 4 Journal. Our process was an industrial one called Aquaponics. Aquaponics is basically the combination of aquaculture (raising fish in a tank) and hydroponics (cultivating plants in water).

    The submersible pump pumps the water throughout the system in which the physics lab would be conducted to investigate the behaviour of water. Next, we started to build the system and bought the fish in a separate container. When we were done building the system, the fish were introduced. Then we integrated the plants into the system and did a Chemistry lab to test the chemistry of water. After these tasks were done, we discussed poster ideas. The poster would involve our data collection and processing of our labs conducted and pictures of our system and its components.

    Although he had been through his share of racial discrimination he instilled in us love for all people regardless of color. He gave us an everyday example of how we were to be treated as well as how we were to treat others. I remember watching the images of violence on the television as young black people marched for their rights in the streets, I remember walking down the streets and being called "Niger" by a car filled with white passengers, I even remember that certain part of town that I was not suppose to be in because I would get beat up by the white people.
