In Parts A and C‚ the relationship between surface area and volume was investigated. Plasticine was formed into a cube and a sphere; both shapes were cut in half. It was found that plasticine volume should not vary‚ two halves have a greater surface area than a whole‚ and cubes have a greater surface area than spheres of the same volume. In Part B‚ the relationship between diffusion and surface area to volume ratio was investigated. Three agar-phenolphthalein-sodium hydroxide cubes of different sizes

Surface area / Volume ratio Experiment Introduction: The surface area to volume ratio in living organisms is very important. Nutrients and oxygen need to diffuse through the cell membrane and into the cells. Most cells are no longer than 1mm in diameter because small cells enable nutrients and oxygen to diffuse into the cell quickly and allow waste to diffuse out of the cell quickly. If the cells were any bigger than this then it would take too long for the nutrients and oxygen to diffuse into

Effects of Air pollution: There are different kinds of negative and harmful effects of air pollution. The effects of air pollution are described below. 1. Global warming: Air pollution causes global warming in a great scale. With increased temperatures world wide‚ increase in sea levels and melting of ice from colder regions and icebergs‚ displacement and loss of habitat have already signaled an impending disaster if actions for preservation and normalization aren’t undertaken soon. 2. Causes

electrical air conditioning was inverted by Willis Havilland Carrier in July 17‚1902 at Buffalo‚ NewYork‚ just one year after he graduated from Cornell university with a masters in engineering. In 1928‚WillisHavilland Carrierimproved and developed the residential air conditioner for private home used which call “weather make”. Air conditioner‚ namely AC or air-con consists of 4 types of systems‚ which are window air conditioner‚split air conditioner ‚ packaged air conditioner ‚ central air conditioning

Background Information Surface area will increase the speed of reaction as the greater the surface of the solid reactants‚ the more particles are required to expose and ‘cover’ the capacity of the solid. Increased surface area results in an increased chance of collisions between reactant particles. Since the collisions become more frequent and abundant‚ the rate of reaction increases. Aim The aim of the experiment is to see if a greater surface area of a dissolvable tablet creates a faster or

AIR ASIA Company profile: Air Asia needs no introduction in ASEAN‚ where it is the leading low-cost carrier‚ connecting people and places across 132 routes‚ 40 of which are offered by no other airline. In 2010‚ the Group‚ which includes affiliates Air Asia Thailand and Air Asia Indonesia‚ reinforced its leadership position with two remarkable milestones: flying its 100 millionth guest and breaking the RM1 billion(ringgit) profit barrier. From an airline with two aircraft plying six routes in Malaysia

When comparing the similarities and differences between virtue theory‚ utilitarianism‚ and deontology we find that they all deal with how one judge’s morality and ethics. These theories all include judging in different aspects‚ whether it is in the moment‚ what happens after‚ or over a lifetime. The ethics and morality behind these theories all deal with what is right‚ or what is best for the present‚ then separate paths as the theories work toward the future. With virtue ethics a person strives

CHAPTER 3: THE MUSCULAR SYSTEM Three Types of Muscle * Muscle tissue is a collection of cells that shorten during contraction which create tension that results in movement * Tendons are touch bands of connective tissue that join muscle with bones Skeletal muscles * Muscles that are attached to bone (by tendons and other tissue) * Comprise 30 to 40% of human body weight * Humans have conscious control (conscious muscle) over these muscles (the brain can tell them what to do)
