The biological explanation for Anorexia Nervosa focuses on the role of neurotransmitters. It suggests disturbances in the levels of serotonin and dopamines are characteristic of anorexia. Bailer et al compared serotonin activity in women recovering from restricting anorexia with those recovering from purging type anorexia with a healthy control group. They found that the group recovering from purging type anorexia had higher serotonin activity. They also found the highest levels of serotonin in women

The Biological Importance Of Water Water plays a huge role in our lives‚ the molecule which is comprised of two atoms of hydrogen and one atom of oxygen bonded together has many complex properties. The molecule maintains a bent shape due to its tetrahedral arrangement and the negative lone pair of electrons on the oxygen. The electrons from both hydrogen and oxygen are joined covalently but the difference in electronegativity lets the electrons from hydrogen get pulled slightly toward the oxygen

length. WHAT ARE THE MAJOR MILESTONES RELATED TO THE PHYSICAL DEVELOPMENT IN ADOLESCENCE? BRIEFLY DESCRIBE THESE MILESTONES. There are many major physical changes that take place during the course of adolescence. Many would argue that the most prominent changes involve puberty and the endocrine system. The various endocrine glands present in the body begin to secrete hormones that influence puberty and initiate physical changes such as: brain development‚ the development of secondary sex characteristics

Task: Discuss two or more biological explanations for the development of schizophrenia. One biological explanation for schizophrenia is genetics. This theory states that a person’s genes determine whether they develop schizophrenia or not. Family studies‚ twin studies and adoption studies have explored the roles of genes in the development of sz. Gottesman conducted a family study and he identified that the closer someone is genetically to a person with sz‚ the more likely to develop sz. For example

individuals who stutter have disagreed with these accusations. Stuttering can have a tremendous negative impact on a person’s life in many ways. New research is being done to disprove the notion that stuttering is a disorder of the mind‚ and rather a biological condition. The thought of stuttering being a potentially genetically or inherited trait may seem shocking to some people. According to Dennis Drayna (2012)‚ who is a researcher at the National Institute on Deafness and Other Communication Disorders

The Biological Importance of Lipids Lipids are organic compounds found in all types of plant and animal cells. They always contain carbon‚ hydrogen and oxygen‚ however the relative amount of oxygen is less than the amount of carbohydrates in lipids. Lipids are polymers and the long chains of repeating units are joined together in a condensation reaction where water is also produced. The most common types of lipids are triglycerides‚ phospholipids and waxes. Triglycerides are formed by three fatty

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 FOUNDATIONS Heredity Heredity refers to the process of transmitting genetic characteristics from parents to offspring. Physical traits and even physical defects are known to be hereditary. Also‚ some mental traits and mental defects are known to be hereditary.

Biological effects of Methamphetamines Maria B. Araiza-Chavez BEH 317 Peter Pingerelli October 26‚ 2010 Abstract Biological effects of Methamphetamines Methamphetamines affect the human body in a physical and neurological and psychological way. The use of meth can lead to devastating effects to the nervous system for example leaving the user with nervous ticks and body jerks similar to a person suffering from Parkinson’s disease. On a physical level‚ the user may show skin sores and
