to us. Another question we could ask from our daily life is that how come we can hear? What is it that we hear? Why do we hear it and deaf people don’t? How do we receive any sound? People use sound all the time. We rely on sounds to communicate. Unexpected noises may warn us of danger. The sounds we hear tell us a lot about our surroundings. Many animals also use sound. Even animals that live in water. Since only the very top of the ocean receives light from the sun‚ animals have difficulty using

Part I. Question 1 Aristotle uses two methods to prove light cannot travel. Besides his empirical explanation‚ where he observes that for the supposed motion of light to go “unnoticed from where the sun rises to where it sets is asking too much” (418b26)‚ he also provides an argument that is understood through the “light of reason.” (418b24) To understand his contention we must refer to his definitions of light and the transparent. The transparent is‚ for Aristotle‚ the medium of sight; it is “what

LIGHT IN PHOTOSYNTHESIS Theory: Leaf discs float normally. When the air spaces are infiltrated with the solution the overall density of the leaf disc increases and the disc sinks. The infiltration solution includes a small amount of sodium bicarbonate. The bicarbonate ions serve as the carbon source for photosynthesis. As photosynthesis proceeds oxygen is released into the interior of the leaf which changes the buoyancy – causing the discs to rise. Since cellular respiration is taking place

Aim In this assignment I am going to carry out a practical examination on a plant (onion) and an animal (cheek) cell under a light microscope. The stain methods I am going to use are iodine for my onion cell and methylene blue for my cheek cell. Introduction All animals and plants are made up of cells. Animal and plant cells are made from millions of tiny cells‚ so small that we are unable to see them with our naked eye. Animals and plants have many features in common within a cell such

Electric Light-Bulb The modern world is an electrified world. The light bulb‚ which was probably one of the greatest inventions of all time‚ profoundly changed humans life by illuminating the night and making it hospitable to a wide range of human activity. Until the light bulb and electricity were invented‚ people could see at night only with candles‚ fires‚ gaslights‚ or oil lamps. The electric light bulb provided brighter light so people were better able to read‚ sew‚ and do other things that

Automatic Street Light [pic] Submitted By: Introduction Automatic Streetlight needs no manual operation for switching ON and OFF when there is need of light. It detects itself weather there is need for light or not. When darkness rises to a certain value then automatically streetlight is switched ON and when there is other source of light i.e. day time‚ the street light gets OFF. The sensitiveness of the street light canal so be adjusted

his future murder comes to Macbeth only at night when no light can bring him back to goodness. Banquo’s murder also happens in the dark. Such evil deeds could only be done in the dark. Then during Lady Macbeth’s sleep walking‚ the only source of light comes from the candle that she keeps by her at night. In fact‚ Lady Macbeth is very afraid of darkness because it makes her remember of all the deeds that happened during the night. (Here‚ light has a positive reassuring role.) In this scene‚ she reveals

of organic compounds such as glucose from inorganic carbon dioxide and water using light as an energy source. This is also known as photoautotrophic nutrition. Carbon dioxide is an energy poor compound which is reduced during photosynthesis There are two main stages: 1. The light dependent reactions that occur on the granal membranes. Pigments are required to absorb and transduce the light energy. Membrane proteins act as electron carriers. 2. The light independent reactions that occur in the
