Listen and Look Here is a list of key terms you will hear and see during the reading and video. Get to know them! Virus: infectious particle made only of a strand of either DNA or RNA surrounded by a protein coat. Disease: a body, organ or system condition resulting from various causes such as infection, genetic defect or environmental stress. Pathogen: agent that causes disease. Vaccine: substance that stimulates an immune response, producing acquired immunity without illness or infection. Antibiotic: chemical that kills or slows the growth of bacteria. Epidemic: rapid outbreak of a disease that affects many people. Bacteria: organism that is within the kingdom Bacteria. Protist: eukaryote that is not an animal, plant or fungus. Protozoa: animal-like protist. Lytic Cycle: infectious pathway of a virus in which host cells are destroyed. Lysogenic Cycle: infectious pathway of a virus in which host cells are not immediately destroyed. Conjugation: process by which a prokaryote transfer part of its chromosome to another prokaryote. Binary Fission: asexual reproduction in which a cell divides into two equal parts. Toxin: poison released by an organism HIV: Human Immunodeficiency Virus- virus that weakens the immune system by reproducing in and destroying T cells; and causes AIDS. Influenza: flu -commonly epidemic disease caused by rapidly mutating virus.taxonomy: branch of science concerned with classification of organisms Domain: division of organisms that ranks above a kingdom in systems of classification that are based on shared similarities in DNA sequences Kingdom: second highest taxonomic category grouping together all forms of life having certain fundamental characteristics in common Phylum: taxonomic category below kingdom that includes a large group of organisms that share one or more fundamental characteristics. Class: taxonomic category below phylum that includes a group of organisms that share a variety of fundamental characteristics. Order: taxonomic category below class that includes one or more families. Family: taxonomic category below order that includes one or more genus. Genus: taxonomic category below family that includes one or more species. It is used as the first word in a scientific name. Species: taxonomic category that includes individuals able to reproduce fertile offspring together. Binomial Nomenclature: scientific naming of species whereby each organism receives a genus and species name. Phylogeny: the evolutionary history for a group of species.
Recall and Review: ANSWER ALL THE QUESTIONS IN COMPLETE SENTENCES. Use the video and your textbook to help you answer the following questions in your binder. A. Chapter 18 (Section 1) 1. Differentiate between living cells and viruses in a Venn Diagram. Living cells Virus Both 2. State the characteristics all pathogens have in common. B. Chapter 18 (Section 2) 3. Draw and label that main parts of a typical virus. 4. Draw and label the lytic and lysogenic cycle.
5. Describe the differences in infection between the lytic and lysogenic cycle. C. Chapter 18 (Section 2) 6. Explain the effects on cells from both the lytic and lysogenic cycles. 7. A wart is caused by a virus that may lie dormant for years before any symptoms appear. Does this resemble a lytic or lysogenic infection? Explain. D. Chapter 17.1 8. State the two ways Carolus Linnaeus classified living things. 9. Explain why biologists use scientific names. 10. Name each taxon in the Linnaean system of classification, from most general to more specific. 11. Describe the difference between a genus and a species. Genus Species
E. Chapter 17.2 12. State the three ways scientists base their identifications of evolutionary relationships. 13. Explain how a phylogenetic tree is similar to a family tree. F. Chapter 17.4 14. State the three domains that exist in the tree of life. 15. Explain what distinguishes the three domains in the tree of life from each other. Domain Name: Explain 16. Analyze. Why are protists, plants, fungi, and animals classified into the same domain but into different kingdoms?
