Effect of light on Silver Halide Salts Aim: To investigate the effect of sunlight and UV light on silver salts and to identify an application of this reaction. Hypothesis: The compounds exposed to sunlight (which already contains UV light) will decompose. The compounds which are not exposed to light (put in a dark place) will not decompose. Theory: Equipment: * 4 x petri dishes * 1 x glass stirring rod * 0.1 mol/L silver nitrate in a dropper bottle * 0.1 mol/L Sodium chloride

think of weight training intensity does someone yelling phrases like those come to mind? Well if it does then you are partly correct‚ but what does weight training intensity actually mean? Following the thread of the last two articles ive done dealing with creating your own workout plan and defining training volume‚ today we’ll look at what training intensity is and how to apply it. WHAT IS INTENSITY IN WEIGHT TRAINING From my research ive found that training intensity meaning is actually

Problem: Dows light intensity and wavelength affect Photosynthesis? Introduction: Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct. It produces sugar and other organic compounds such as lipids and proteins. The sugars are then used to provide energy for the organism. Light reaction is the series

Introduction: Photosynthesis is a process to which some autotrophs such as plants produce their own food. It has two stages or reactions light-dependent and light-dependent reactions. The light dependent reactions are the first stage‚ where energy from sunlight is captures in Photosystem 2 and then 1‚ the electrons generated in Photosystem 1 then moves along the electron transport chain. The moving of electrons causes a hydrogen ion gradient that is used in the final step to produce ATP‚ by the

Planning Exercise Aim To investigate the effect of phosphate on cell division in root tips. Background knowledge Phosphate ions (macronutrients) are needed large amounts by plants. They are required for root growth. For the root tips cells to divide‚ mitosis has to occur. Phosphate is needed for production of ATP which provides energy for mitosis to occur. DNA replication occurs during interphase of the cell cycle. DNA is made up of nitrogen containing base‚ pentose sugar and phosphate group

I can model Photosynthesis with The Law of Conservation Of matter and The Law of Conservation of energy. I know this because of the articles i’ve read the articles are Discovering the secrets of Photosynthesis‚ Joseph Priestley‚ Discoverer of Oxygen and Photosynthesis: Yucky chemistry Details. Photosynthesis is a good example of the Law of conservation of Energy because in the process of Photosynthesis the radiant energy is absorbed by the plant. The radiant energy is then turned into chemical

Effect of Exercise on Heart Rate. Aim: The aim of this experiment is to find out how different intensities of exercise effect the heart rate I will measure it in beats per minute using a polar heart rate monitor. Hypothesis: I predict that as I increase the intensity of the exercise I do‚ that my heart rate will increase. This is because as I exercise more intensely I will need more blood to my muscles to supply oxygen and take away carbon dioxide; therefore my heart is going to have to beat

Lab: Cellular Respiration in Yeast Lab Report Form Your Name: Katlin Moore “What do you think? – What do you know?” Questions: In this lab‚ we will investigate the effect of sucrose concentration on the rate of cellular respiration in yeast. Under specific conditions‚ yeast will convert sucrose into glucose and then use this glucose in cellular respiration. Yeasts have been used by humans in the development of civilization for millennia. What is yeast? How have humans used yeasts?

The Effect of Distance from Light Source on the Rate of Photosynthesis Introduction: The effect of distance from the light source on the rate of photosynthesis was tested in this experiment. This was tested to find ways to accelerate the rate of photosynthesis. If plants are placed closer to a source of light‚ then their rate of photosynthesis will be higher because they are receiving more light. Experimental Design: The independent variable is the distance of the beaker from the light source
