The Discovery of Biological Taxonomy Taxonomy is the scientific classification of living organisms. It is known that two main naturalists were responsible for discovering and founding this classification method‚ John Ray and Carl Linnaeus. Biological Taxonomy has a hierarchy of seven main ranks; Kingdom‚ Phylum (Division if it is Botany)‚ Class‚ Order‚ Family‚ Genus and Species. These classify every living thing from Animals to Bacteria. Some of the classification system is written English

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

Campbell’s Biology‚ 9e (Reece et al.) Chapter 5 The Structure and Function of Large Biological Molecules In Chapter 5‚ the principles of chemistry covered in earlier chapters are applied to the understanding of biological polymers and lipid membranes. The emphasis is on properly linking monomers and their polymers‚ and on the structural and functional diversity of the different polymer types. Particular attention is given to protein structure‚ because this is central to understanding subsequent

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

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

Biochemical imbalances in neurotransmitters cause depression; most notably noradrenalin‚ serotonin according to the permissive amine theory is a controller and dopamine.

human lifespan are yet to be unraveled. Many theories‚ which fall into two main categories: programmed and error theories‚ have been proposed to explain the process of aging‚ but neither of them appears to be fully satisfactory. These theories may interact with each other in a complex way. By understanding and testing the existing and new aging theories‚ it may be possible to promote successful aging. Keywords: Aging‚ Biological‚ Theory‚ Programmed‚ lifespan Why do we age? When do we start aging?

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

A protein is a Biological polymer made up of as different amino acids joined by peptide bonds. A protein is formed by amino acids which are the basic building block of a protein components of an amino acid include a :C-carbon atom‚ H-Hydrogen atom‚ H3N+ - Amino Group‚ COOH- - Carboxyl Group‚ R- this group varies from amino acid to amino acid. There are 20 amino acids‚ each differing in its R group. Two examples are: Glycine‚ its R group being H(Hydrogen) and Phenylalanine its R group being CH2 (Carbon
