The Effect of Light Intensity on the Rate of Photosynthesis of Elodea in the Aquarium Aim The aim of this experiment was to investigate the relation between the light intensity and photosynthesis rate of Elodea in an aquarium using a simulator. Background Photosynthesis is metabolic pathway in which plants use carbon dioxide and water to produce glucose by the aid of light energy from the sun. Light energy is usually absorbed by chlorophyll; a green pigment in plants. The equation of…

The Aurora Borealis (Northern Lights) along with the aurora australis have always fascinated people, (Northeren Lights or Aurora Borealis Explained) “so much even that some people travel thousands of miles just to see them.” These lights occur when super charged electrons from the solar wind combine with the elements within the Earth’s atmosphere. The electrons will begin to move upward towards the earth’s atmosphere and on their way up they will encounter atoms of oxygen and nitrogen when they…

bright days and dark nights. But today when nightfall, we quick to switch on lights, spoiling the benefit of natural darkness. By showing that Paul experience both artificial light and natural darkness, Paul shows that his point of view might be insightful. In the third , Paul uses an anecdote to allude to the health problems caused by artificial lights. He sites that the World Health Organization has voiced that “light pollution reduction efforts and glare reduction efforts at both the…

chloroplasts because it allows the process of light reactions to take place. Photosystem l, makes NADPH from chlorophyll and is responsible for the transfer of electrons with high energy levels to additional molecules. Whereas, photosystem II produces ATP with the usage of an electron from light. Moreover, the thylakoid space is beneficial for the function of photosynthesis due to the reason being that it helps generate the concentration gradient of protons and absorb light in photosynthesis.…

of millimeter and submilímetro (submillimeter light has slightly shorter wavelengths than millimeters light, whose wavelengths are measured in millimeters). These ranges fall along the boundary between bands for radio and microwave electromagnetic spectrum, and have longer wavelengths than optical light. This band of light allows astronomers to probe the dark cores of gas clouds to study the formation of stars and planet, and see a very distant light that was shifted to the red end of the…

‘Deepavali’ is what Diwali was known as, it is derived from two words, deep as in a candle (light); avali means a row. Hence, the meaning of Deepavali is a row of lights; this has an ancient story behind it. Over a billion people celebrate Diwali making it the most observed holiday in India. On this day lanterns, electric lights and fireworks illuminate the night to celebrate the victory of good over evil, light over dark and knowledge over ignorance. From snow covered mountain tops to the…

but they share a common purpose, and it’s important to know how they work. Light passes through the cornea of the eye, which has the job of protecting the eye and refracting the light so some of it can enter the pupil. The pupil is surrounded by the iris, which may come in different colors, has the ability how much light can enter the pupil through the process of shrinking or dilating itself, acting like camera. Once light enters the…

darkness around him, he sees her as a light. When he talks to her on the steps, he remembers it like this, "The light from the lamp opposite our door caught the white curve of her neck, lit up her hair that rested there and, falling, lit up the hand upon the railing". This light is his childhood thought about love. He has now moved passed this into a darker realty of realistic expectations. The narrator who is recalling this childhood memory as an adult uses light and dark elements to show a…

Our every decision and its probable outcomes manifest. Perhaps, not here, but somewhere... This means the most improbable scenarios are bound to run their course in a distant universe extremely different or remarkably unrecognisable from our own. Light creates space, wherein it indirectly generates time. On a universal scale, our the sum of thoughts, words and actions churn the wheel of Karma. (The Moral Principle and/or Spectrum of Cause & Effect) Time progresses in accordance with the forms,…

In experiment 1 there were five cuvettes of decreasing concentrations from the initial 0.01 mg/ml concentration of Fast Green solution (cuvette 1). The diluted concentration of cuvettes #2 through #5 were calculated using the dilution formula, C1V1 = C2V2 ; the calculations for the dilute concentrations are in Results section. The concentration for each tube were as follows: 0.015 mg/ml for tube 1, 0.0075 mg/ml for tube 2, 0.00375 mg/ml for tube 3, 0.001875 mg/ml for tube 4, and 0.000935 mg/ml…
