Dry Wallum The dry wallum is a harsh environment that is battered by the sun and wind every day and with a base of porous sand; water availability is very scarce and must be conserved. The abiotic factors in the dry wallum are that the area is exposed to high amounts of sunlight which causes a loss of water in the leaves through transpiration. Since the wallum is so dry and hot; bush fires play a major cycle in the dry wallum which the trees have adapted to cope with. The roots of the plant and

Gas exchange is a biological process that is essential for the survival of an organism. The purpose of this process is to obtain oxygen from the environment (which is necessary for cellular respiration‚ and to dispose of CO2‚ a bi product of respiration. An efficient gas exchange system has 3 requirements. It must have a large surface area over which the gases can diffuse. A large surface area maximises the amount of area available for the gases to exchange. It must also be moist. Oxygen must first

Arrangement of Vascular Tissues in Flowering Plants • Xylem and phloem often are grouped together -> vascular bundle • Cambium -> lies in between xylem and phloem -> divide and differentiate -> form new xylem and phloem tissues -> thickening of stem Movement of Substances Into and Within Flowering Plants Entry of Water and Nutrients into Plants • Absorption of water -> root hairs -> grow into close contact with liquid around them • Thin film of liquid surrounding soil

The Evolution Theory Evolutionists have failed in every endeavor to prove that evolution or evolutionary processes could have taken place. By Muneeb Baig‚ (Grade 10) Posted: 15 Safar 1423‚ 28 April 2002 The modern theory of evolution was developed by Charles Darwin‚ an amateur English naturalist‚ in the 19th century. He proposed that all of the millions of species of organisms present today‚ including humans‚ evolved slowly over billions of years‚ from a common ancestor by way of natural selection

The Rise of the Superbugs A Superbug is a bacterium that can live in the human body and has the ability to withstand all forms of antibiotic medication. Superbugs are becoming increasingly significant in modern medicine as they are becoming more and more resistant to antibiotics. Antibiotics were discovered in 1928 by Alexander Fleming (Walsh and McManus‚ 2000). This resulted in a huge movement forward in medical history and even greatened human life expectancy. Since then antibiotics have been
