9.2 Maintaining A Balance 1. Most organisms are active in a limited temperature range. | | * Identify the role of enzymes in metabolism‚ describe their chemical composition and use a simple model to describe their specificity on subrates. | * Role of enzymes in the metabolism:Biological catalysts that control all chemical reactions within the body. They are specific to one action. | | * Chemical composition:Catalysts produced by cells made up of proteins (linked amino acids)

Individual plants and animals could not exist by its self on earth. All organisms need other organisms for survival. An ecosystem is a community of living organisms. An ecosystem maintains an important balance in order for all organisms within the ecosystem to survive. The balance involves carbon‚ food‚ nitrogen‚ oxygen and water. The sun supplies the energy needed by ecosystems. Plants absorb the energy and use photosynthesis to convert it to sugar. There are nutrients in the air‚ soil and water

True e Energy is recycled within an ecosystem. False 2 Give an example of an organism that is: a a producer in a terrestrial ecosystem Typical producers in a terrestrial ecosystem would be expected to include flowering plants‚ conifers‚ ferns and mosses. b a producer in an aquatic ecosystem In an aquatic ecosystem‚ producers

Homeostasis is the ability of a cell or organism to maintain a stable internal environment despite fluctuating external environmental conditions. An animal will maintain this state of equilibrium through adjustment mechanisms that keep the conditions of its cells and body within a narrow range (SOC 2 n.d.). Homeostasis is crucial to the survival of an organism‚ by maintaining a stable environment‚ it enables cells to be functioning optimally‚ giving an organism the best chance of surviving to a reproductive

DNA is the “blueprint” for the individuality of an organism. The organism relies upon the information stored in its DNA for the management of every biochemical process. The life‚ growth and unique features of the organism depend on its “blueprint”. The parts of DNA which have been linked with specific features or functions of an organism are called genes. Molecular biologists have discovered many enzymes which change this structure in living organisms. Some of these enzymes can cut and join strands

and the application to real life situations. Concept of Habituation The concept of habituation begins with the understanding of the orienting response or orienting reaction. The orienting response or investigatory reflex is the reaction an organism has to any stimulus for the purpose of identifying the source of it and

These components affect living organisms in many ways. Some of the soluble components and emulsions are poisonous‚ particularly to small organisms that do not have protective coverings or shells- Fish larvae‚ single celled algae and many kinds of plankton are vulnerable and these are the basic foundation of the marine food chain. In shallow water these toxic substances may directly kill algae‚ coral and sea grasses. These components may also be passed in the food chain or directly ingested or absorbed

Cloning is the process of creating genetically identical organisms Asexual organisms are reproduce by cloning themselves Human identical twins are clones of each other Clones have identical DNA but can have different personalities History of Cloning 1938 –Hans Spemann proposes a “fantastic experiment” – to replace the
Premium Cloning Bacteria Organism
At the beginning of the semester‚ samples of bacteria were obtained from various sources. Two bacterial colonies were isolated from plates that were incubated in the lab and these bacteria became the basis for this project. The bacterial cultures were maintained and used for various physiological‚ cultural‚ and biochemical tests and observations over several weeks. The purpose of culturing bacteria over half the course of the semester was to learn various techniques used in microbiology labs and
