BIO 120 Objectives 1 General Zoology BIO 120 Lecture NOVA Loudoun Campus Fall 2013 Chapter 1 Objectives Please respond to the following questions in preparation for the lecture evaluation on this material 1 What is biology What is zoology 2 What are seven properties common to all life HINT students should be familiar with order reproduction growth and development energy processing response to the environment regulation and evolutionary adaptation 3 What is the doctrine of modern zoology HINT students should know the goal and three guiding biological principles What are organic evolution genetics and ecology 4 What are three components of the cell theory 5 What is the hierarchy of living systems HINT students should include the terms atoms macromolecules cells tissues organs organ systems organisms populations species communities ecosystems and biosphere 6 Who authored On the Origin of Species When was it published What is the theory of evolution What is natural selection 7 Who is The Father of Modern Genetics What are the five components to Mendel s Laws of Inheritance 8 What are five disciplines of biology What are five subdisciplines of zoology 9 What is science What are the two components of science HINT students should understand investigation and accumulation What are the four characteristics of science HINT students should understand materialism testability repeatability and self correcting 10 What are inductive and deductive reasoning What are eight features of the so called science cycle HINT students should refer to Figure 1 4 and understand curiosity questions observation hypothesis and prediction experimentation and testing conclusion communication and modify or trash 11 What is a hypothesis What is a theory What is a scientific law BIO 120 Objectives 1 Science study of world accumulation and modification of new information Components of Science Investigation research and experiment Accumulation share results Characteristics of Science Materialism must study something that follows natural laws Testability experiment Repeatability inter rater reliability repeated trials Self correcting modifying theories and hypotheses Zoology sub discipline of biology Biology study of life Ecology Anatomy Physiology Embryology Genetics Botany Ornithology Ichthyology Herpetology Parasitology Immunology Entomology Properties of life Order Energy processing metabolism rely on environment to harness and process energy Reproduction have some way to carry on genes Growth quantitative and development qualitative Response to the environment Regulation homeostasis Evolutionary adaptation heritable genetic variation Doctrine of modern zoology Evolution change in population over time Genetics how genetic information is passed heredity Ecology study of organisms and environment biotic and abiotic factors Cell make up DNA Plasma membrane Cytoplasm collection of cell parts and fluids Cell Theory All cells come from pre existing cells Cells are the basic units of life All living things are made up of cells Hierarchy of living systems Atoms BIO 120 Objectives 1 Macromolecules carbohydrates proteins lipids nucleic acids Cells Tissues cells with similar functions Organs tissues with similar functions Organ system Organisms Population same species in specific area Community two or three species in a specified area Ecosystems interaction of abiotic and biotic factors in specified area Biosphere anywhere life can be sustained Authored On the Origin of Species by Means of Natural Selection or the Preservation of Favoured Races in the Struggle for Life Charles Darwin Published in 1859 Theory of evolution Organisms are molded by their environment Change over time Based on competition and limited resources Natural selection Mendel The Father of Modern Genetics Mendel s Laws of Inheritance Each parent contributes one factor of each trait shown in offspring Males and females contribute equally to traits of offspring One trait may dominate another trait Two members from each pair of factors segregate independently of each other Two members of each pair of factors segregate from each other during formation of gametes Inductive reasoning specific to general Deductive reasoning general to specific Science Cycle Observation Question Hypothesis prediction Experiments and testing Conclusion greater impact importance Modify trash self correcting characteristic Hypothesis preliminary Theory more accepted through most of the scientific community more evidence for it Scientific law truth that cannot be disproved over time
