Biology- Change in pH Aim: To investigate the affect that change in pH levels has on a particular enzyme‚ in this case amylase. Hypothesis: In this investigation I expect as the pH reaches the optimum level‚ the rate of reaction will be fastest‚ compared to other pH levels. It is also suspected that after the enzyme has reached optimum level the enzyme activity will decrease. Through further study of the optimum level of amylase I found that the enzyme usually has an optima pH of 8. It is known

Essay Question 1 Explain how changes in habitat can lead to habitat fragmentation. How does this affect the population of animals in that area? Species lose their habitats when those habitats are destroyed outright‚ but habitat loss also occurs when habitats are altered through more subtle processes‚ including fragmentation and other forms of degradation. The sudden and complete elimination of habitat is uncommon at large scales; instead‚ what we usually witness is gradual‚ piecemeal degradation

Introduction Last week‚ my Biology class and I went down to the Port Kembla Rock Platform. While we were there we surveyed five different sectors about the rock platform and recorded them‚ these included: 1. Surveying the abiotic characteristics of the rock platform 2. Observing the abundance and distribution of the Black Periwinkle (Nerita Atramentosa) 3. Observing the feeding relationships and food webs of the organisms 4. Finding the adaption’s of organisms 5. And Observing the human impacts
