Biology – HSC Online Extract from Biology Stage 6 Syllabus (Amended October 2002) © Board of Studies‚ NSW 9.2 Maintaining a balance: 1. Temperature range Background: All organisms are adapted to a particular environment with its characteristic temperature range. The temperature range allows the organism’s enzymes to control its metabolism by operating at their optimum efficiency within this range. Some organisms are adapted to live at high temperatures (80 - 100oC) and these are called thermophiles

HEAT TRANSFER Heat transfer‚ also known as heat flow‚ heat exchange‚ or simply heat‚ is the transfer of thermal energy from one region of matter or a physical system to another. When an object is at a different temperature from its surroundings‚ heat transfer occurs so that the body and the surroundings reach the same temperature at thermal equilibrium. Such spontaneous heat transfer always occurs from a region of high temperature to another region of lower temperature‚ as required by the second

Three Worksheet 1. What is a carbohydrate profile? Why are they used as a diagnostic or identifying tool? (2) Carbohydrate profiles are specific information on the type and amount of carbohydrate that a product contains. It is used to identify and differentiate two closely related species. 2. What are the carbohydrate profiles of the organisms you tested? (2) The yeast carbohydrate profile came out with glucose and fructose positive and Mannitol negative. The staph epidermidis was glucose

AP Biology Study Guide Chapter 11 1. Categorize chemical signals in terms of the proximity of the communicating cells. Local signaling – a. Paracrine signaling – a secreting cell acts on nearby target cells by discharging molecules of a local regulator (a growth factor‚ for example) into the extracellular fluid. b. Synaptic signaling – a nerve cell releases neurotransmitter molecules into a synapse‚ stimulating the target cell. Long distance signaling- c. Hormonal signaling – specialized

Analyzing the transfer of technology from one place to another can be a very difficult task. People have tried to trace the origins of specific technologies and map out what cultures it affected‚ why and what impact the technology had on history. Books have been written on conclusions that authors have made after doing the research I have suggested. I believe that obtaining the information to write a book about this subject is extremely hard and confusing‚ this is a personal assumption that I have

Explain how the production of oxygen through photosynthesis by cyanobacteria affected the composition of the atmosphere and the development of other organisms. 23. A rock sample from Mars is reported to contain fossil evidence of life. What kind of fossil would you expect it to be? Explain your answer. 24. Where in North America would you look if you wanted to find evidence of Archean life

One purpose of this paper is to show the importance of biology in our everyday life. The subject of this paper is the cause and affects of micro-organisms that are in the human digestive system. Article of choice‚ (Adnan‚ 2010) Benefits of Microorganisms to Humans‚ Retrieved February 8‚ 2013. This article was of interest because there are many bacteria that we encounter in our daily lives and it was informative to know that all bacteria is not bad. In fact‚ there needs to be a balance between the

This will be the second time I make one of these essays and as a person who has experienced an AP course I am thrilled to express what I have accomplished and the objectives I want to attain for my future in AP. Before entering my first AP Class there was only a feeling of fright and a part of me was ready to bail so I could run back to the normal classes. However‚ now that I look back I am glad that I did not run away. Due to the Pre-AP and AP course that is offered by the school I was capable of
