BIOD 101 MODULE 2 EXAM & REVIEW GUIDE Actual Questions and Verified Answers Portage Learning. Describe evolutionary adaptation (generational adaptation) and give an example. Smaller genetic changes that allow for better survival of an organism (camouflaged animals surviving longer and producing more within their given environment). What is an adaptation? What characteristic of life would an adaptation fall into? Change or a process that allows an organism to become better suited for its environment (physical adaptation of crab's hard shell. Behavioral adaptation of a squirrel hibernating). Response to the environment. A system of living and non-living things in a region best describes a(n): Ecosystem What are the 3 domains that comprise the Linnaean Classification system? 1. Archaea 2. Eubacteria 3. Eukarya List the 7 most widely accepted characteristics of living organisms. 1. Order 2. Evolutionary adaptation 3. Regulation 4. Energy transformations 5. Growth and development 6. Responsiveness 7. Reproduction What is the purpose of a phylogenic tree? A branching diagram that shows the relationship between different levels of Linnaean classification taxa. They visually represent dichotomies concerning evolutionary relationships and enable scientists to unite phylogeny with the classic Linnaean classification systems. Each branch point represents where the two organisms likely share a common ancestor. A group of one particular species living within defined boundaries of a community best describes a(n): Population True or False: Extremophiles are a small sub-set of the Archaea domain that live in extreme environment. True Bacteria that cause illness are considered: Pathogenic (cause illness through the production of exotoxins and endotoxins). Describe what an exotoxin is and given an example. Proteins that are secreted by the bacterial cell (Vibrio cholera "diarrhea"). Describe what an endotoxin is and given an example. Present inside the cell or can be the lipopolysaccharide components of the outer membrane of some bacteria (gram-negative). These toxins are only released upon the death of the bacterial cell when the cell wall begins to decompose (Salmonella "food poisoning"). Describe what a symbiotic relationship looks like between two organisms. A long-term relationship between two organisms in which one or both organisms benefit from the paired interaction. Examples of symbiotic relationships.
