Sleep enables our brains and bodies to rest‚ equipping us to take on the next day. A normal sleep cycle consists of 5 stages‚ 1‚ 2‚ 3‚ 4‚ and REM. If sleep is disturbed it can cause problems with health and everyday life. Stage 1 is when sleep is light and one can be awakened easily. In this stage we begin to drift in and out of sleep‚ the eyes move slow and muscle activity slows. Stage 1 lasts about five minutes and is followed by stage 2. Stage 2 eye movement stops and brain waves become slower

The Australian land and its flora and fauna are very unique compared to other continents. There are three main reasons for this‚ biological isolation‚ geological stability and the erratic climate. Firstly biological isolation has meant that over the last 40 million years Australia has been separated from all other continents‚ this was the cause from the separation from Gondwanaland around 55 million years ago. This means the Australian flora and fauna has been able to evolve in isolation

Growth and Development Shannon Ogbeni Kaplan College Growth and Development The process of growth and development is a random manner but is gradual and regular. There is a particular pattern of development for instance; development proceeds from head to toe and from the midline to the periphery (outside boundary or surface of something). Different body parts grow at a different rate‚ all body parts cannot grow at the same time. Growth is a continuous and gradual process‚ all body parts continue

Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite
