Answer it correctly to obtain valuable clues to solve the mystery. Get A Clue Viruses are studied in biology because They are living organisms They are active in living cells They are in Eubacteria They are going extinct Bacteria have a POSITIVE affect on our lives by… Cleaning oil spills Preventing decomposition of dead animals Producing dental caries Consuming improperly preserved foods Which of the following contains only a nucleic acid? Prion Prophage Viroid Proteobacteria Viral DNA becomes integrated into the host cell’s DNA in which cycle? Binary Fission Lytic Mitotic Lysogenic What is the size of the largest known virus? 250 micrometers 250 nanometers 250 millimeters 250 centimeters Antibiotics are effective against viruses because antibiotics interfere with the metabolic processes of the virus. False True Animal viruses infect specific cells because the host cell has receptors for the glycoproteins on the virus. False True Which of the following contains only protein? Viroids Prophage Prions Proteobacteria What is smaller than bacterium, is able to be crystallized, and causes disease in tobacco plants? Tobacco Masiah Virus E. coli Rhabdovirus Tobacco Mosaic Virus Hepatitis, rabies, and shingles are examples of diseases caused by Viruses Bacteria Fungus Protists Viruses have membrane bound organelles. False True This is viral DNA integrated into a bacterial genome. Provirus Prophage Proteobacteria Prion A typical virus consists of Nucleic acid and carbohydrates Only Nucleic acid Only carbohydrates Nucleic acid and protein Viruses that use reverse transcriptase to transcribe DNA from RNA are called ? Reverse Viruses Bacteriophages Retroviruses Prions The protective outer coat of a virus is the Capsul Capsid Cell Wall Peptidoglycan Smallpox is caused by a bacterium. True False Who was the first scientist to crystallize a virus? Stanley Fox Alexander Fleming Jonas Salk Wendell Stanley Which term describes a shape of a capsid? Rhombus Icosahedron Rectangle Parabola Which term refers to the disintegration of the host cell? Lysogenic Lytic Lysis Release This is a viral genome that has incorporated itself into a host genome. Prophage Proteobacteria Provirus Prion Vaccines are often ineffective because viruses are constantly changing. False True The earliest known group of living organisms on Earth was Bacteria Viruses Fungi Protists Bacteria are Eukaryotes Animals Viruses Prokaryotes Gram-positive bacteria stain ________ with a Gram-stain. Pink Yellow Purple Blue Bacteria contain Circular chromosome Linear chromosome No Chromosome RNA The cell wall of a bacterium contains Phosphate Protein Prion Peptidoglycan This type of cell does not have any membrane-bound organelles. Eukaryote Prokaryote Animal Plant Bacteria have ribosomes. True False This will allow a bacterium to survive harsh conditions. Plasmid Endospore Capsid Envelope Bacterial cells will transfer pieces of genetic material in a process called Conjugation Transformation Transduction Sexual reproduction What can be harmful to any living organism? Pathogen Flagellum Pilli Friday “Ancient” bacteria are also known as ___________. Eubacteria Archaebacteria Monera Extremobacteria “True” bacteria are also known as _____________. Ancient Bacteria Archaebacteria Eubacteria E. coli A virus that infects bacteria is called a ____________. Bacteriophage Prophage Decomposer Bactophage A bacterium that breaks down dead tissues is a __________. Bacteriophage Eater Decomposer Recycler Bacteria replicate via Conjugation Mitosis and Meiosis Binary fission Budding Archaebacteria that live in salty conditions are called ________. Extreme Thermoacidophiles Extreme Halophiles Extreme Methanogens Extreme Anaerobes Archaebacteria that live in extrememly hot conditions are called ________. Extreme Halophiles Extreme Methanogens Extreme Thermoacidophiles Extreme Anaerobes The best way to control bacterial growth in a hospital is Sterilization Refrigeration Dehydration Isolation How can you prevent becoming ill from the bacterium Salmonella?
