main factor that leads to the damage of optic nerve is elevated pressure in the eye. The optic nerve is the main visual nerve of the eye. It transmits the images we see back to the brain for interpretation. The shape and tone of the eye is maintained by a pressure within the eye‚ which ranges between 8 mm and 22 mm of mercury. When this pressure is too low‚ the eye becomes softer‚ while an elevated pressure causes the eye to become harder. The optic nerve is the most susceptible part of the eye to high

Cell Membrane Structure Phospholipids are arranged in to layers‚ called the bilayer. They only have 2 fatty acids‚ this is because the third fatty acid is replaced by a negatively charged phosphate group. The phosphate heads are polar‚ in other words attracted to water‚ therefore they are hydrophilic. The lipid tails are non-popular as they’re not attracted to water and therefore known as hydrophobic. When phospholipids are added to the water‚ they rearrange themselves so that the hydrophilic heads

Impulse and Momentum Lab Part I: As the first lab of the Physics 2 curriculum‚ our class completed a lab experiment that introduced us students to a new concept that would be a foundation to the future topics that we learn in this class. In this lab activity‚ we used a lab cart on a flat track to compare the collision of the cart with a force sensor with and without the plunger during different trials. The materials that we would need for this activity are a lab cart on a flat track‚ a timer

LAB REPORT 1 - LAB 7 CELL MEMBRANE FUNCTION Marisela Camacho Legarreta June 30‚ 2013 ACTIVITY 1 INTRODUCTION Be aware that all molecules have kinetic energy‚ which means that is an active energy that is always in motion. Molecules move in all different ways and this create an evenly distributed movement which is best known as diffusion. Diffusion is the movement of molecules from a region of their higher concentration to a lower concentration. METHODS Check the reaction of different

Internet Censorship Internet is one of the most powerful means of communication in the history of humankind. It brings people together and has potential sources of information as well as entertainment. Besides‚ it has a lot of dangers and harms for the users (especially for children). In Australia‚ the idea of ‘internet censorship’ began since 2003 by the Australia’s prominent think tank when researched about online habit of Australian teenagers and the dangers related to internet.
