Biology - ANSWERSThe scientific study of life Cell - ANSWERSBasic unit of all living things Levels of Biological Organization - ANSWERSAtom, Molecule, cell, tissue, organ, organic system, organism, population, community, ecosystem, biosphere Emergent Properties - ANSWERSCharacteristics of life: organization, metabolism, homeostasis, response, reproduction and development, adaptation Energy - ANSWERSThe ability to do work TMetabolism - ANSWERSAll the chemical reactions that occur in a cell Photosynthesis - ANSWERSProcess that converts solar energy into chemical energy of carbohydrates Homeostasis - ANSWERSThe maintenance of internal conditions within certain boundaries. Stability Adaptation - ANSWERSAny modification that makes an organism better able to function in a particular environment Evolution - ANSWERSThe change in population of organisms over time to become more suited to the environment Genes - ANSWERSAre passed down to the next generation. They determine characteristics of organisms and are composed of DNA Taxonomy - ANSWERSThe branch of biology that identifies names and classifies organisms Systematics - ANSWERSThe study of evolutionary relationships between organisms
Classification Catagories for Organizing Diversity or Taxa....From most inckusive to least inclusive - ANSWERSDomain, kingdom, phylum, class, order, family, genus, species What are the Domains - ANSWERSArchaea, Bacteria, and Eukarya What is the major difference between prokaryotes and eukaryotes? - ANSWERSProkaryotes do not have a nucleus, eukaryotes do have a nucleus What is the main difference between Archaea and Bacteria? - ANSWERSArchaea can live anywhere including harsh environments. Bacteria cannot live in harsh environments. What are the kingdoms of domain sunsets? - ANSWERSProtists, plants, animals, fungi Binomial Nomenclature - ANSWERSScientific name. Universal, Latin. Two-part name. First word is genus and is always capitalized. Second word is species and always written in lowercase. Both words are italicized. Ex: Homo sapiens (humans), Zea mays (corn) Scientific method - ANSWERSThe standard series of steps used in gaining knowledge for research Steps of the scientific method - ANSWERSObservation, hypothesis, experiments and data collection, conclusion Observation - ANSWERSUse senses to gather information Hypothesis - ANSWERSA tentative explanation for what was observed, developed through inductive reasoning, and testable Experiment - ANSWERSA series of procedures designed to test a hypothesis Experimental Design - ANSWERSThe manner in which a scientist conducts an experiment Experimental Variable - ANSWERS(Independent) it is the factor being tested Test Group - ANSWERSExposed to the experimental variable Control Group - ANSWERSIs not exposed to the experimental variable Data - ANSWERSResults of an experiment. Should be observable and objective
Formula - ANSWERSTells you the number of each kind of atom in a molecule Ionic bond - ANSWERSForms when electrons are transferred from one atom to another. By gaining or losing electrons, atoms fill their outer shells and are more stable (octet rule). Attraction of oppositely charged ions holds two atoms together in an ionic bond. Covalent Bond - ANSWERSResults when two atoms share electrons Nonpolar covalent Bonds - ANSWERSSharing of electrons is equal. The electrons are not attracted to either atom to a greater degree Polar Covalent Bonds - ANSWERSSharing of electrons is unequal. Electrons are attracted to one atom more than the other Hydrogen Bond - ANSWERSAttraction of a slightly positive Hydrogen atom to a slightly negative atom in the vacinity. Hydrogen bonds are usually weak but many hydrogen bonds are strong Properties of water - ANSWERSHigh heat capacity, high heat of evaporation, is a solvent, Molecules are cohesive and adhesive, frozen water is less dense than liquid. It is a Polar Covalent Hydrogen Bond. Calorie - ANSWERSThe amount of heat energy needed to raise the temperature of 1g of water to 1℃ Hydrophilic - ANSWERSIonized or polar molecules attracted to water Hydrophobic - ANSWERSNonionized and non polar molecules that cannot attract water Cohesive - ANSWERSAllows water to flow freely without molecules separating. Adhesive - ANSWERSThe ability to adhere to polar surfaces; water molecules have positive and negative poles pH - ANSWERSIs a measure of hydrogen ion concentration in a solution
