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

Patterns of Wealth and Poverty Throughout history there have always been those who have it‚ and those that don’t. Yet how do we distinguish between the two groups? There has been a number of ways thought up‚ such as if a families total earnings are sufficient to obtain the minimum necessity’s to live without extra spending. Another theory is that instead of defining the poor as those who income is too low‚ they are poor if their incomes are considered too far removed from the rest of the

Explain the sequence and rate of development from birth to 19 years:- Emotional and social development Emotional development is the expected pattern of a Childs ability to feel and express and increa vsing range of emotions. Social and behavioural development is the expected growth pattern of a child’s ability to relate to the world around them. There are various theories and models that show the different aspects of the development stages. I have combined these

of wind turbines to a bigger blade that have a slower motion so that it is less likely for the migrating birds to nest on the turbines or collide with the fast moving blades. Patterns of migration of birds have been spotted around Point Pelee National Park but the wind turbine project management will not take migration patterns into account. This article also states that the number of birds killed by cats‚ cars‚ and buildings are bigger than the numbers killed by the wind turbines‚ but still is a big

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
