Effect of Clay in Soil on Plant Growth INTRODUCTION: In this experiment‚ the relationship between the amount of clay in the soil and plant growth was measured over a two week time period. The manipulated variable in the experiment was the amount of clay in the soil‚ specifically one hundred and twenty grams of clay mixed with eighty grams of soil‚ and the responding variable was the plant growth. Although clay in soil can be beneficial for plant growth in the sense that is provides good moisture

Population growth was still relatively slow and steady for the majority of human existence‚ until the last 200 years‚ which managed to increase numbers by 700% in less than 0.00005% of our time on earth. This insane rate of growth has highlighted many problems clearly‚ which include our need for greater amounts of limited resources‚ as well as the health and environmental

Environment ’s effect on Growth of Bread Molds I. INTRODUCTION A. BACKGROUND OF THE STUDY Molds are species of fungi. There are many different kinds of molds‚ some of which are specially adapted to grow in particular environments or on particular surfaces. Unlike plants‚ molds cannot produce their own food‚ so they need an external source of energy and nutrients. Molds (and mildew) are fungi. Fungi are neither plant nor animal but‚ since 1969‚ have their own kingdom. The fungi kingdom

Hypothesis The optimum temperatures of Alcalase and Savinase will be different. Above and below their optimum temperatures activity will decrease. Biological explanation This investigation is designed to look at the effect of temperature on the activity of the proteases Alcalase and Savinase. By the end of it I hope to know the optimum temperature of both proteases. The substrate I am going to use during the experiments is the protein gelatin‚ which is a translucent‚ colourless‚ brittle solid

Effect of Substrate Choice On Growth Of Mealworms Abstract: The experiment is designed to show which substrate A or B will better nourish a mealworm. A mealworm was placed in each substrate for a period of seven days and the change in mass from Day 1 to Day 7 was compared. The data was compiled and statistically analyzed. The experiment failed to reject the null hypotheses that there would be no difference in the two substrates regarding meal worm growth

Effects of Human Activities on the Lake Ecosystem I. Introduction On the first exercise of the Environmental Biology class‚ the students have learned what an ecosystem is and what its significance to the survival of the living and non-living are through analysis of forest and agro-ecosystems. The ecosystem as the basic unit for ecological study (Evans‚ 1956) consists of the complex of interacting organisms inhabiting a region with all the non-living physical factors that make up their environment

Effects of pH on fungal amylase activity BI 211 November 25‚ 2011 Introduction In recent years‚ the uses of microorganisms have become a huge importance to industry and sparked a large interest into the exploration of enzyme activity in microorganisms. Amylase is one of the most widely used enzyme required for the preparation of fermented foods. Apart from food and starch industries‚ in which demand for them is increasing continuously‚ amylase is also used in

IB Biology Sheran Gu Meghan Lena Nov. 15th Influence of pH on Enzyme Activities How does the pH of solution influence the speed of enzyme activities? Enzymes are protein catalysts and chemical that speed up chemical reaction without being involved in the reaction. They are involved in the human digestive system to help people digest food more efficient. Food are substrates to be break down and absorb through the digestive system in the body. Substrate is a molecule that bond with the active site
