Cow’s eye dissection AIM ~ To locate and distinguish specific parts to an eye of a cow‚ in particular‚ its lens. OBSERVATIONS ~ Before actually beginning the dissection of the cow’s eye‚ we were about to sketch a fairly relative picture of our observing’s of the exterior body of the eye. The eye‚ having almost completely being sheltered in fat and muscle‚ was quite firm and only the cornea and optic nerve was identified. By further cutting down the fat‚ we were able to spot a rather tough pinkie

The Eye is the organ of sight. Eyes enable people to perform daily tasks and to learn about the world that surrounds them. Sight‚ or vision‚ is a rapidly occurring process that involves continuous interaction between the eye‚ the nervous system‚ and the brain. <br><br>When someone looks at an object‚ what he/she is really seeing is the light that the object reflects‚ or gives off. This reflected light passes through the lens and falls on to the retina of the eye. Here‚ the light induces nerve impulses

1. SURFACE RUNOFF INTRODUCTION: Runoff means the draining or flowing off of precipitation from a catchment area through a surface channel enters into a stream channel. It is convenient to visualize three main routes of travel; overland flow (air hujan limpahanpermukaan)‚ interflow‚ and ground water flow (air dari punca bawah tanah). 1 Runoff results from rainfall occurrence in a hydrologic catchment. Rainfall-runoff relations are Interflow/subsurface and base flow/groundwater flow

Surface Area Formulas In general‚ the surface area is the sum of all the areas of all the shapes that cover the surface of the object. Cube | Rectangular Prism | Prism | Sphere | Cylinder | Units Note: "ab" means "a" multiplied by "b". "a2" means "a squared"‚ which is the same as "a" times "a". Be careful!! Units count. Use the same units for all measurements. Examples |Surface Area of a Cube = 6 a 2

The doctrine of covering the field is a doctrine in constitutional theory that applies in federal constitutions where legislative powers are shared between the federal government and the federating states in Enumerated Lists. It applies only to legislative acts (statutes) made by the federal and state legislatures under the Concurrent Legislative List. In the US‚ the expression‚ covering the same ground‚ was used in Houston v Moore 18 US 1 (1820). The doctrine simply means that where there is a

Surface Waves: Understanding its movements I. Introduction We treat here an important wave phenomenon‚ the surface wave. It occurs in many physical systems both mechanical and electromagnetic. Mechanical surface waves can exist at the interface between two media with different densities such as the oceans and air. Ordinary sea waves and tsunamis are surface waves. Seismic events can produce both longitudinal and shear waves at the earth’s surface‚ resulting in earthquakes. Electromagnetic surface

Surface area Surface area is the measure of how much exposed area a solid object has‚ expressed in square units. Mathematical description of the surface area is considerably more involved than the definition of arc length of a curve. For polyhedra (objects with flat polygonal faces) the surface area is the sum of the areas of its faces. Smooth surfaces‚ such as a sphere‚ are assigned surface area using their representation as parametric surfaces. This definition of the surface area is based on methods

Functioning Eye (Emmetropia)</b> <br>The eye is the organ of sight. It is used in almost everything we do‚ from playing sport to reading. A normal and well functioning eye can focus objects and images‚ both near and far‚ perceive depth and adapt to changes in light. <br> <br>The perception of depth is due to having two separate eyes creating two separate images‚ while the ability to adapt to light change is attributed to the iris and the dilator muscles. However these two aspects of the eye are not

INTRODUCTION The human eye is one of the most complex organisms in the human body – second only to the brain. It is the organ which gives us the sense of sight‚ allowing us to observe and learn more about the surrounding world than we do with any of the other four senses. We use our eyes in almost every activity we perform‚ whether reading‚ working‚ watching television‚ writing a letter‚ driving a car‚ and in countless other ways. Most people probably would agree that sight is the sense they value
