systems within multicellular organisms‚ with reference to the need to respond to changes in the internal and external environment and to co-ordinate the activities of different organs. Organisms need to respond to external stimuli‚ e.g. temperature‚ oxygen concentration and levels of sunlight. These may be over time‚ e.g. winter fur to summer fur‚ or quickly‚ e.g. changing size of pupils. Internal environments change too- the build up of carbon dioxide as a result of respiration changes the pH of

Analysis of Oxygen bearing Organic compounds Abstract The Unknown sample in the experiment can be tested to yield results such as 1° (primary)‚ 2° (secondary)‚ 3° (tertiary) alcohols. Tests such as the dichromate test‚ Tollen’s test‚ Lucas test‚ DNPH test and iodoform test would be very useful in determining the type of alcohol that the unknown sample belongs to. In the experiment‚ the unknown sample underwent series of testing to identify what property of alcohol it belonged to and the result

take part in how each of the different animals operate to carry out their way of life. Gas exchange is simply the intake of oxygen and the release of carbon dioxide. Further on in this written report will explain how the different animals respire and how the animals use their environment to their advantage. Insects have spiracles on their exoskeletons to allow air (oxygen) to enter the trachea. This is a structural adaptation. The spiracles are located laterally along the thorax and abdomen of

Primary Succession Primary Succession is an ecological succession process that occurs in an environment with no prior inhabitants. Primary succession is the changes in species composition over time in a previously uninhabited environment.
