The Effect of Vitamin C on Plant Growth Aim: To determine the effect of salt/ sugar/ caffeine/ vitamin C on seed germination. Hypothesis: The plant will grow slowly or die due to the Vitamin C. Equipment: * 2 cups * 2 measuring cups * Water * Vitamin C/ orange Juice * Soil * 4 seed (2 for each cup) * A ruler Method: 1. Pour ¾ of soil into each cup 2. Plant 2 seeds into each cup.

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

molecule.(3) The molecules that enzymes help to accelerate is called substrates‚ and when enzyme is combined together with the substrate‚ it is called enzymes- substrate complex‚ and after the enzyme finish catalyzing‚ the substrates before is turned into what we called product. Enzymes‚ just like other catalyst‚ will not be used up as a part reactant through the reaction. So enzymes can be used over and over again. The substrates fit into the enzyme like a key fits into a lock (3). Enzymes have other

larger enzyme molecule. Moreover‚ the molecule that the enzyme acts upon (substrate) fits precisely into the depression and forms an enzyme-substrate complex. The substrate molecule is held into the active site by bonds that temporarily form between certain amino acids of the active site and groups on the substrate molecule. Enzyme-substrate complex: The enzyme-substrate complex formed when the enzyme binds with its substrate lowers the activation energy (minimum amount of energy needed to activate

A2 Practical Investigations Title: The effect of Temperature on the growth of Aspergillus oryzae Develop a Hypothesis This particular investigation is to discover how a range of temperatures effects the growth rate of the fungi Aspergillus oryzae. Most fungi’s tend to survive within the temperature range of 5-35oC‚ with the optimum depending on their normal environmental temperature. The fungi Aspergillus oryzae is heterotrophic which means they taken in their food from dead organic matter and cannot

This is due to the large impact culture and ethnicity has on diet‚ which results in changes in heath. As a result the choices and selections of food that people make‚ in the classes of foods they eat‚ will vary widely. Different cultures may encourage or frown upon consumption of different foods by individuals who belong to their groups. Also the consumption of different

Because growth can come in many ways‚ GNP and GDP are not particularly good measures. More so‚ economic growth can occur from having more people in an economy. If economic growth occurs more slowly than the population growth‚ then there can be economic growth‚ but the average person is less well-off. As economic growth is measured as the annual percent
