Effect of Light Intensity The effect of different light wavelengths was tested in the following experiment. The rate of photosynthesis can be affected depending on the light treatment it receives. With the aid of DPIP acting as NADPH in photosynthesis‚ it was possible to observe the reaction as it took place. Samples were created with dark‚ 24 cm‚ 30 cm‚ and 49 cm light treatments. The absorbance was measured in five-minute intervals for each sample and recorded in an appropriate table. When analyzing

My name is Quinlin Beets‚ and I come to you from John Hopkins University where I study marine archaeology. The legend of Atlantis has been one of the oldest and most spellbinding of all the world’s mysteries. It has puzzled civilizations for many years. Civilization first heard about Atlantis in 330 B.C by Plato. Plato was a Greek philosopher. He wrote stories about Atlantis called “Timaeus” and “Critias”. He lived from about 428 B.C to 348 B.C. For two millennia no one thought about Atlantis.

Light‚ Color and Solutions Effects of Concentration and Cell Path Length on a Solutions Absorbance To examine the relationship between color of a solution and the light it absorbs. When it comes down to it our eyes do a accurate job of depicting and distinguishing colors. The purpose of this experiment is to take that a little farther‚ become more precise. With the use of a spectrophotometer one can determine the wavelength and intensity of the light absorbed. By adding a light source to the

Discussion: 6. The ph solutions that were used were 2‚4‚7‚9 and 10. All of these solutions affected the beetroot‚ but the most acidic solutions were the ones that did the most damage to the membrane. This is because the ph affects the proteins within the phospho lipid bi-layer. The acidic ph breaks the hydrogen bonds therefore denaturing the proteins and allowing beetroot pigment to secrete form the cell. 7. The ethanol solutions that were used were 11%‚ 25% and 50% ethanol. The beetroot cell was almost

Research question : How does the different light intensity affect the rate of photosynthesis in plants? Objective : To investigate the relationship between different light intensity (by having the source of light at different distance to the plant discs which is at; 10cm‚ 15cm‚ 20cm‚ 25cm‚ 30cm‚ and 35cm ) and rate of photosynthesis of plant. Introduction : Photosynthesis is the process where light energy is absorbed by green plants to convert the raw materials (carbon dioxide and water) into

Investigation of the effect of light intensity Equipment: * Data loga * Light sensor * Bulb * Metre ruler X3 Variables: Independent variable – distance of the light sensor from the light source (m) Dependant variable – intensity of light (lux) Control | Why it needs to be controlled? | How will you control it? | Bulb | There are different watts in different bulbs | Use the same bulb‚ but if your one does break half way through the experiment you can use another bulb with the

students of eight respondents‚ 3 males and 5 females‚ completed the task in which they participated in a Stroop Colour-Word Test. The condition is the ability to recognize the colours‚ the performance difference between male and female‚ the performance difference between age‚ the reaction time and the effect of colour word interference in order for the participants to speak out the color ink of the words in each condition. Participants responded slower in the incongruent condition as the word did not match

and Temperature on Beet Cell Membrane Integrity Introduction: • Cell membranes are vital to proper cellular function • Cell membranes consist of a lipid bilayer made up of phospholipids • Phospholipids are amphipathic molecules meaning they have a dual nature in that they show both hydrophilic (water-loving) and hydrophobic (water-fearing) properties • The amphipathic nature of phospholipids causes them to spontaneously form bilayers in water based solutions o The inner

the U.S. is just changing its method for building up U.S. well-disposed governments by advancing low-intensity majority rules system. “Low-intensity conflict is a limited politico-military struggle to achieve political‚ social‚ economic‚ or psychological objectives. It is often protracted and ranges from diplomatic‚ economic‚ and psychosocial pressures through terrorism and insurgency. Low-intensity conflict is generally confined to a geographic area and is often characterized by constraints on the
