UNIT #1 BIO QUESTIONS AND ANSWERS ALREADY PASSED

UNIT #1 BIO QUESTIONS AND ANSWERS ALREADY PASSED Describe what is meant by the term 'Biology' and give examples of sub-fields within the discipline. is the study of the life. The exploring, learning, discovering, researching all of life. List and recognize examples of the characteristics displayed by living organisms. Organization: Cellular Organization Reproduction: Sexual Reproduction Energy Processing(Metabolism): Producers and Consumers Homeostasis:Ability to stay the same. Respond to the Enviornment-> Evolution as Population. Compare methods for categorizing living organisms at the Kingdom and Domain levels. Domains: 1.Archaea & 2.Bacteria-HAVE NO NUCLEUS(Prokaryotes),BOTH ARE SINGLE CELLED ORGANISMS,and are microscopic. 3.Eukarya- HAS NUCEUS(Eukaryotes), are single celled and multicelled, has 4 kingdoms: -Protista-algea. -Plantae-all the plants. -Fungi-mushrooms to yeasts. -Animalia-includes animals with and w/o vertebrates. Compare and contrast, and recognize examples of the following terms: taxonomy, Archaea, Bacteria, and Eukarya Taxonomy-study of classifying organisms into hierarchies groups. Archaea/Bacteria-Prokaryotes Eukarya-Eukaryotes Recognize examples of and apply biology's key themes (listed below) to various scientific discoveries. Organization: Cellular Organization Reproduction: Sexual Reproduction Energy Processing(Metabolism): Producers and Consumers Homeostasis:Ability to stay the same. Respond to the Enviornment-> Evolution as Population. a. Emergent Properties aka:Biological Hierarchy b. Unity Within Diversity #3 Domains- Archaea-->(4 Kingdoms: Protista, Fungi, Plantae, Animalae), Eukarya Bacteria. -Taxonomy-study of classifying organisms into hierarchies(groups) -Charles Darwin-->Natural Selection Evidence for decent with modification. From a common ancestor. Describe the biological hierarchy and define and recognize examples of: atom, molecule, cell, tissue, organ, organ system, individual, population, community, ecosystem, biome, and biosphere. atom-smallest unit of a chemical element. molecule-two or more atoms held together by strong chemical bonds cell-smallest and most basic unit of life, building blocks of all living things. tissue-collection of coordinated an specialized cells that fulfill a particular function for the organism. A group of cells that performs a unique but fairly narrow set of tasks for the body. organ-body parts composed of different types of tissues functioning in a coordinated manner. organ system-in animals, groups are of organs are networked into organ systems, through large reigons of the body.- individual- population- community- ecosystem- biome- biosphere- Relate the theme of emergent properties to the biological hierarchy. pg.21 Define evolution, natural selection, and adaptation and describe their relationships to all other discoveries in biology. Natural Selection-is an evolutionary, mechanism that changes overall genetic compensation of population by favoring the survival and reproduction of individuals best suited to the environment. Individual level, based on enviornment, random process.] Adaptation-good match between population and its habitat. Define, recognize examples of, and relate to one another: inductive reasoning, deductive reasoning, hypothesis-based science, controlled experiment, observational study, independent variable, dependent variable, controlled variables, discrete data, continuous data, correlation and causation. Inductive Reasoning-all believed true or found true most of the time. Discrete Data-usually words- colors, groups, months, etc.)Can be numbers (ex. Ranges: Age groups 20-24) Always histogram- BAR graph Continuous Data-Numerical, never stops, ALWAYS SCATTER PLOT(LINE GRAPH),(height, length, weight, age, temperature). Correlation- sort of relationship. Causation-cause and effect Differentiate between a scientific "theory" and a regular person's definition of "theory." Scientific Theory- explanation based on repeatedly reported facts Draw a graph when given data and then interpret the relationship (positive, negative, none). (+)-both increasing (-)-one decreases as the other increases None-no relationship, unrelated or connected.
