Enzymes and their importance in plants and animals (25 marks) Enzymes are biological catalysts‚ which accelerate the speed of chemical reactions in the body without being used up or changed in the process. Animals and plants contain enzymes which help break down fats‚ carbohydrates and proteins into smaller molecules the cells can use to get energy and carry out the processes that allow the plant or animal to survive. Without enzymes‚ most physiological processes would not take place. Hundreds of

industrial organizations in Canada are synonymous with the branch plant economy phenomenon. In general‚ "the term branch plant economy refers to a convenient shorthand term to describe a regional economy where a large proportion of the employees are in establishments owned by firms whose head office lies outside the region" (Watts 1). In Canada‚ branch plant economies are subsidiaries of companies based abroad‚ mostly in the U.S. A branch plant economy is a strategic tool used by transnational corporations

organic materials which are used for cellular function (Wikipedia). Plants are an example of this kind of organism. A current scientific topic in regard to photoautotrophs is the topic of non-native invasive plants. When a plant is non-native‚ or exotic‚ it means that it is not originally from the United States. They are often brought to an area by accident‚ possibly for agricultural or horticultural purposes. An invasive plant is one that is established‚ then expand and reproduce on their own

which is used to heat water to create steam. This steam turns turbines which produces electricity. In a standard fossil fuel electricity station the same thing occurs except the burning of the fossil fuel heats the water to create steam. Nuclear power plants can produce more energy using less fuel and thus they are seen as a more environmental friendly source of power. What are the Disadvantages of Nuclear Power? Due to many countries looking to find more environmentally friendly ways of producing

of fertilizers on plant growth | | | Year 11 Biology Year 11 Biology Abstract An investigation was carried out to compare the effect between inorganic and organic fertilizers on plant growth. Tomato seedlings were used‚ which were divided into 3 groups - the inorganic fertilizer group‚ the organic fertilizer group and the control group. Besides using different fertilizers‚ all of the seedlings were planted in the same condition. The result has shown that the plants using organic fertilizer

Nuclear Power Plants and Safety Since the humans use energy sources such as wood‚ coal‚ and oil to produce electricity‚ people want to use better energy sources to produce electricity more. By the mid twentieth century‚ scientists found the method of making incredible energy by using uranium as nuclear fission. Today there are about 400 nuclear power plants around the world and more than 100 nuclear power plants in United States (Howstuffworks). In addition‚ nuclear reactors produced a lot of

spp. have deleterious effects on other plant species. In the study of Bughio et al.‚ using the eucalyptus camaldunlensis as allelopathy agent against Acasia nilotica‚ The Eucalyptus leaf litter and leaf litter extract also caused significant reduction in seedling vigour index of Acacia nilotica. Based on the results of their study it is concluded that allelopathy is a concentration-dependent phenomenon‚ as the concentration of the E. camaldulensis treatments increases‚ its effect increases.
