BSC 101 Wodika: Exam One Questions And Answers All Correct.

Explain why the scientific method is a myth - Correct Answers Science is not linear. The scientific method is oversimplified and many experiments answer the same question. In actual science, there is a lot of back and forth between questions and evidence. Science is ITERATIVE Define iterative in science - Correct Answers series of experiments that circle back to answer the same question to form a deeper understanding of the topic(think the game of pinball) What is involved in the actual science ("actual scientific method")? - Correct Answers-exploration and discovery -testing ideas -community analysis and feedback -benefits and outcomes What inspires exploration and discovery? - Correct Answers new technology, societal problems, or curiosity What is involved in the early stages of exploration and discovery? - Correct Answers making observations, asking questions, finding inspiration, exploring literature, and sharing data/ideas What is central in the early stages of exploration and discovery? - Correct AnswersTalking to other scientists/ looking at other data What must a scientist do in the exploration and discovery stage? - Correct Answerslearn about what is already known about the topic What is the testing process? (simple definition) - Correct Answerstesting ideas with evidence What does scientific testing involve? - Correct AnswersInvolves figuring out what we would expect to observe if an idea was correct and comparing that idea to what we actually observe. Fix the misconception: Science can only prove or disprove an idea. - Correct AnswersScience rejects or accepts ideas based on supporting or refuting evidence but conclusions can be revised if warrented by new evidence True/False: All science is tentative - Correct AnswersTrue What is the purpose of community analysis and feedback? - Correct AnswersEnsure accuracy of the scientific information. It makes science self correcting What is the purpose of benefits and outcomes? - Correct Answers-allows for developing new technologies, solve practical problems, and make informed decisions -scientists are motivated by potential application of sciences What are the four elements of scientific explanations? - Correct AnswersPrediction, hypothesis, theory, and law define prediction - Correct Answersa prediction is what you expect to happen if your hypothesis is true. Define hypothesis - Correct Answers-Are not guesses. -They are based on prior knowledge. -Plausible explanations that have not been tested yet. define theory - Correct Answers-have a lot of evidence -used to explain a broad sense of phenomena -they are not tenuous -have no contradictory evidence -has many hypothesis within it define law - Correct Answers-an explanation that describes directly what is constantly observed -often expressed mathematically What is the difference between a law and theory? - Correct Answersa law predicts what happens while a theory proposes why. A theory will never grow up into a law, though the development of one often triggers progress on the other Describe scientific culture (4) - Correct Answers-scrutiny: examine each others work to make sure it is a valid conclusion(peer review) -Honesty & Integrity: publishing the whole story(no omitting or manipulating data) -attribution: giving credit -ethics: treating subjects with respect and making sure their aren't conflicts of interest in research, funding, or consulting What are the three parts of a scientific theory? - Correct Answers-hypothesis/theory + -expected results/observations = actual results/observations Define independent, dependent, control variable, control group, and experimental group - Correct Answers-independent: what you change -dependent: what is changed as a result of the IV -control: what is kept the same among all experiments -control group: group that is left in an environment it would naturally occur in -experimental group: group experimented on How does the scientific community help make science a self-correcting process?(4) - Correct Answers-the community evaluates and decides if the claims are as strong as the evidence -help generate new ideas/interpretations -remove bias -help motivate one another define biology - Correct Answersthe study of living organisms and their interactions with one another and their environments What can all living things do?(7) - Correct Answers-have organized structures made up of at least one cell -respond to stimuli -reproduce -evolve through adaptation of natural selection -grow and develop -maintain homeostasis -process energy How are atoms, molecules, macromolecules, and cells related to each other? - Correct Answersan atom makes up a molecule which makes up macromolecule(like dna) What is the order of biological organization?(cell) - Correct Answerscell, tissue, organ, organ system, organism, population, species, community, ecosystem, biosphere What is the order of biological organization?(species) - Correct Answersspecies, genius, family, order, class, phylum, kingdom, and domain What are the characteristics of domain archaea? - Correct Answers-have a cell membrane -many have a cell wall. -has nucleotide -has ribosomes -lives in extreme places True or False: All living things have ribosomes and a cell membrane - Correct Answerstrue What are the characteristics of domain bacteria? - Correct Answers-have a cell membrane -have a cell wall -have nucleotide -have ribosomes -are very common to humans(symbiotic) What are the three shapes and names of domain bacteria? - Correct Answers-spheres:cocci -rod shaped:bacilli -spiral:sparilla What are the characteristics of domain eukarya? - Correct Answers-have nucleus -have cell membrane -have membrane bound organelles True/False: Bacteria and Archaea are as different as bacteria and eukarya - Correct Answerstrue define prokaryote - Correct Answersa unicellular organism that lacks a nucleus or any other membrane-bound organelle Define Eukaryote - Correct AnswersAn organism made up of cells that have a nucleus enclosed by a membrane. What are the characteristics of domain eukarya: protists? - Correct Answersdivided into 12 kingdoms (kelp is an example) What are the characteristics of domain eukarya: kingdom fungi? - Correct Answers-heterotrophic(get food from other sources) -cell walls made of chitin (mushroom is an example)
