and behavior. Biological psychology explores behavior through genetics‚ evolution and physiological‚ especially through the study of the nervous system. Biological psychology explores biology in an effort to understand behavior. It investigates how human brain connects to the consciousness. In order to understand biological psychology research has been done to gather background information on the history and the importance to how man understands the brain and how it functions.

BIOLOGICAL HAZARDS Biological hazard are acquired from disease causing microorganism and the poisonous toxins they may produce. Biological hazard are far the most dangerous foodborne hazard in the food service and food retail businesses. These includes harmful microorganism seen only in the microscope 1. BACTERIA 2.VIRUSES 3. PARASITES 4. MOLDS 5. YEAST Other living organism are: • Insects: RODENTS FARM ANIMAL DOMESTIC PETS BIRDS FISH PLANTS TRANSMIT DISEASE TO HUMAN BEING

Biological vs Chemical Pest Control All living things strive to survive‚ but unfortunately the needs of other creatures sometimes conflict with our needs. An example of this conflict is the struggle between pests and humans. Pests are creatures that injure or kill plants or domestic animals‚ transmit disease‚ cause economic damage or are a nuisance in some other way. They eat our food crops or ornamental plants‚ infect plants that are useful to us‚ make us sick by transmitting infectious organisms

Biological Theories “Biological theories of crime focus on the physiological‚ biochemical‚ neurological‚ and genetic factors that influence criminal behavior. However‚ such theories also stress the complex link between a person ’s biology and the broad span of social or environmental factors that sociological theories examine” (Denno‚ 2009). Biological factors that contribute to crime are something neurological or chemical related‚ which is not to be confused with a genetic factor that is inherited

Alcoholism: Nature Versus Nurture For years people have argued that alcoholism is a choice and not a learned or inherited disease. These people will normally agree that yes‚ children are in fact influenced by family‚ but purely of a social nature‚ and that this disease is actually caused by poor economic status‚ poor social upbringings‚ or merely by imitating the behaviors of those who raised them. However‚ research has proven that in a great deal of cases there is in fact enormous basis for alcoholism

Biological Level of Analysis Learning Outcomes 1. Outline the principles that define the biological level of analysis. a. Patterns of behavior can be inherited: There is innate behavior “hard-wired” in organisms that is carried on through genetics. It makes certain stimuli generate certain response and is usually evolutionary. b. Animal research may inform our understanding of human behavior: Biological analysis of animal behavior can be used to predict similar results in humans

Alcoholism is a disease that can be treated‚ but through research. I have found that there is no cure for the disease. I t is noted that nearly 14 million people in the U.S. (7.4 % of Americans) abuse alcohol or are alcoholics (Dorsey‚ Larson‚ Segal1). Severe alcoholism can also lead to organ damage such as cirrhosis of liver‚ epilepsy‚ and gastritis. Because alcoholism is a disease‚ genetic and environmental factors have plenty to do with its development. To support my belief that alcoholism is

Biological Science Lesson 1 Zoology - branch of biology that deals with the life of animals. 1. Morphology - studies forms and structure of animals. a. Gross anatomy - performs surgical technique ; dissection (cutting up). b. Paleontology - studies pre-historic forms of animals through fossil. 2. Histology - study of tissues & organs‚ their structure‚ functions & composition at a microscopic level. 3. Cytology - study of the structure & function and its parts at microsopic level or
