Biological organization is embedded with emergent properties. These properties are based on a hierarchy of structural levels‚ each level building on levels below. Atoms make up the lowest level ordered into complex biological molecules. At the highest level of organization‚ the biosphere makes up all the environments on Earth. Descending down the ecosystem includes both living and nonliving organisms and consists of particular physical components that allow each to interact with one another. All

Biological Theories of Aging Human Growth and Development Introduction Aging is a biological phenomenon all the living things are undergoing. We are not sure about anything in the world except the aging. We are approaching getting nearer to the death from the time of the birth onwards. No living thing in the world has the ability to defeat death as it occurs sometimes naturally and sometimes accidently. Aging has different dimensions like physical‚ psychological‚ and social. There are

The Role Catalysts In Chemical Reactions‚ Their Importance In Industry‚ Problems and New Developments OXFORD AND CAMBRIDGE SCHOOLS EXAMINATION BOARD. General Certificate Examination - Advanced Level Chemistry (Salters’) - Paper 3 mock. ROBERT TAYLOR U6JW. A Catalyst is a substance that alters the rate of a reaction. The catalyst remains unchanged at the end of the reaction. The process is called catalysis. In this report I aim going to explain the role of catalysts in chemical reactions and their

Describe and evaluate biological explanations of schizophrenia (24 marks) Schizophrenia is a psychotic disorder characterized by distorted thinking‚ impaired emotional responses‚ poor interpersonal skills and a distortion of reality. It is the most common of psychotic disorders that‚ in most countries around the world‚ affects around 1 per cent of the population. In terms of explanations for the disorder‚ two central types of explanations arise – psychological explanations and biological explanations. Whereas

The Biological Approach to psychology focuses on the body‚ with emphasis on the brain and nervous system. Psychologists attempt to examine our behavior and our mental processes through our physiological reactions to situations in the world around us. One such example is the way your heartbeat increases when you’re scared‚ our how your palms perspire when you lie. There’s no true way to tell exactly how many biological systems are influenced by our thoughts and feelings‚ but thanks to advances in

there is not a single way of addressing that problem. Here after is a brief investigation of “two of the approaches” we have been taught in Psychology “Biological and Social approaches”. What are “biological” and “social” approaches in psychology? “Biological approach” in psychology “examines thoughts‚ feelings‚ and behaviours from a biological point of view”. It is thought that we are consequence of our genetics and physiology. “Social approach” in psychology studies how people act‚ think‚ and

The Biological Structure of Water Water is a substance with the chemical formula H2O: one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom. Its structure enables it to carry out many important functions in the body. Water molecules are charged‚ with the oxygen atom being slightly negative and the hydrogen atoms being slightly positive. These opposite charges attract each other‚ forming hydrogen bonds. These are weak‚ long distance bonds that are very common and

AO1 2 Types – Genetic and Biochemical Genetic – depression seems to run in families and a number of studies have shown a correlation between the biological closeness of the relationship and the likelihood of developing depression. Biochemical imbalances in neurotransmitters cause depression; most notably noradrenalin‚ serotonin according to the permissive amine theory is a controller and dopamine.

Importance of stereoisomers in a biological system Isomers are compounds that have the same molecular formula but different structural formulas. Stereoisomers are isomers that have the same sequence of bonded atoms‚ but they differ in their three dimensional orientation in space. [pic] shown above is an example of the two types of Stereoisomers; Enantiomers‚ which are stereioisomers which are non-superimposible mirror images‚ much the same as one’s left and right hands are the same

Outline and evaluate the biological approach to psychopathology (12 marks) The biological approach is widely used in diagnosing and treating mental illness. The theory suggests that mental illnesses occur due to a physical cause. Physical causes include genetic inheritance‚ viruses‚ toxicity‚ physical trauma for example a head injury or perhaps an imbalance of hormones bought on by stress. These physical‚ external occurrences can distort thinking‚ emotion and behaviours in some people. Studies
