Subject Title : Biology Program : Diploma Program (IB) School Year : 2014-2016 Instructor : Jeffrey Joseph Y. Araula‚ MMM NATURE OF THE SUBJECT Biology is the study of life. The first organisms appeared on the planet over 3 billion years ago and‚ through reproduction and natural selection‚ have given rise to the 8 million or so different species alive today. Estimates vary‚ but over the course of evolution 4 billion species could have been produced. Most of these flourished for a

Abstract: The object of this experiment was to study how different environmental conditions affected the rate of transpiration of a plant. The environmental factors we looked at were the affects of various temperatures and different light amounts in the different temperatures. We found that as the temperature warmed up‚ the rate of transpiration was higher. When the temperature was at five degrees Celsius‚ the rate of transpiration was very low. When we took out half of the light source and measured

Biology Assignment Transpiration rates between Exotic vs. Native plants In this investigation we will be looking at transpiration. The topic we will be focusing on is transpiration rates between native plants as well as exotic plants. We will be experimenting with 2 native plants as well as 2 exotic plants. The reason we are experimenting on this topic is because of Australia’s dry weather‚ we are wanting to find out which plants will be able to hold more water during Australia’s peaking tempretures

Sandalwood is the name of a class of fragrant woods from trees in the genus Santalum. The woods are heavy‚ yellow‚ and fine-grained‚ and unlike many other aromatic woods they retain their fragrance for decades. As well as using the harvested and cut wood‚ essential oils are also extracted from the woods for use. Both the wood and the oil produce a distinctive fragrance that has been highly valued for centuries. Consequently‚ the slow-growing trees have been overharvested in many areasThe sandal tree

Open Ended Investigation aim To photograph six different organisms (not including humans)‚ classify them to the level of ‘family’‚ determine one characteristic that places them in each of their groups‚ and then use those organisms to construct a dichotomous key. Method Collecting Photographs of Organisms 1. Walk to a location with natural flora and fauna. (In this case I went to the Jim Ring Reserve) 2. Photograph at least two different species of ducks‚ and if possible‚ other birds which reside
