\Biological Intercations Biological interactions are the effects organisms in a community have on one another. In the natural world no organism exists in absolute isolation‚ and thus every organism must interact with the environment and other organisms. An organism’s interactions with its environment are fundamental to the survival of that organism and the functioning of the ecosystem as a whole. In ecology‚ biological interactions can involve individuals of the same species (intraspecific interactions)

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 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

One of the focuses of a criminologist‚ is to determine the cause of crimes and determine the motivation offences. Throughout history‚ many criminological theories have been put forth to explain the development of crime‚ resulting in various modern theories which incorporate the individual‚ social‚ structural and cultural reasons for crime. However‚ one of the first theories of crime advanced‚ was the concept of biological positivism. Although this theory has gone in and out of favour over the course

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

Experiment title: Preparation of Biological Materials for Microscopic Examination Objectives: 1. To learn how to use a microscope. 2. To study the cell structure of starch grains‚ onion cells and cheek cells. 3. To differentiate the difference between starch grains‚ onion cells and cheek cells. Introduction: Microscope is an optical instrument use to magnify micro objects that hardly or impossible to be observed by naked eyes‚ so that the objects can be studied. Compound light microscope

González‚ Aurea March 6‚ 2013 Question #1 For many years biological anthropologists have been trying to identify race through genetics but race is not determined biologically. The closest aspect to a biological feature in grouping people is cline; geography making people of the same area in the world similar. Human variation‚ however‚ is classification of skin color‚ eye color; characteristics that are genetic and unchanging genes. Genetic traits have nothing to do with race; it influences
