ratio on the rate evaporation of water in different sized containers. By measuring the time it takes for the whole amount of water to evaporate‚ a conclusion can be made about the validity of the surface to volume ratio in regards to the biological process of diffusion. Research Question: What is the effect of the surface area to volume ratio on the evaporation of water? Variables: - Independent: o Surface area in cm2 of the top most surface of water in the container. - Dependent: o Rate of

Blood Pressure Anatomy And Physiology Breven Sellers 11/3/2014 Arteries • Arteries are thick walled‚ yet they are elastic enough to stand pressure from the heart pumping at a fast rate. The arteries job is to transport blood away from the heart‚ usually only transporting highly oxygenated blood‚ having just left the lungs and on its way to the body’s tissues Arterioles • There are smaller branches of the arteries called arterioles‚ they connect to the capillaries. • Arterioles are the main

number of specific circumstances which cause or aggravate congestion; most of them reduce the capacity of a road at a given point or over a certain length‚ or increase the number of vehicles required for a given volume of people or goods. About half of U.S. traffic congestion is recurring‚ and is attributed to sheer weight of traffic; most of the rest is attributed to traffic incidents‚ road work and weather events. Traffic research still cannot fully predict under which conditions a "traffic jam" (as

advantages of road transport in comparison to other modes of transport. 1. Less capital quality:- Road transport required much less capital investment as compared to other modes of transport such as railways and air transport. 2. Door to door services: - The outstanding advantage of road transport is that it provides door to door or warehouse to warehouse services. 8. Saving in packing cost: - As compared to other modes of transport‚ the process of packing in motor transport is less complicated

Lab # 2 Diffusion & Osmosis Introduction Kinetic energy‚ a root of energy stored in cells‚ causes molecules to hit into each other and move in new directions. Diffusion is the result of this contact. Diffusion is the random movement of molecules to an area of lower concentration from an area of higher concentration. Osmosis is a type of diffusion. This is the diffusion of water through a selectively permeable membrane from a region of higher water potential to a region of lower water

The purpose of the lab was to investigate osmosis‚ which was successfully achieved because there was a change in the potato’s mass which was due to the net movement of water either into the potato cells or out of the potato cells. In the 0.400M solution‚ the potato decreased in mass‚ this was due to the reason that the solution was hypertonic. There was a higher concentration of solute and lower concentration of water in the solution than there was in the potato cells. This led the water to travel
