- Q1Having a standard taxonomic system benefits the scientific community by allowing scientists from all over the world to do which of the following?Use a similar system to classify the impact of removing species from ecosystemsHave a common system for the classification of locations containing fossilsUnderstand how other scientists classify predator–prey relationshipsHave a common understanding in the classification of organisms30s
- Q2Scientists around the world use a standardized taxonomic system. Why would scientists want to use a taxonomic system that is standardized?In order to avoid confusion with the identification of organismsIn order to place organisms in different groupsBecause Linnaeus established the systemSo that Latin names can be applied for a practical purpose30s
- Q3The gray squirrel, Eastern fox squirrel, and red squirrel are all different species of squirrels. Why is having a scientific name for each species of an organism important?To allow organisms to be placed in many classification levels at the same timeTo keep the classification system from being altered as new organisms are discoveredTo standardize the naming and organization of organisms to avoid confusionTo prevent existing named organisms from having their names changed as they become extinct30s
- Q4The branch of science which deals with classifying, identifying, and naming organisms is –systematicstaxonomycladisticstaxidermy30s
- Q5Which response does not support the need for the international science community to have a standardized taxonomic system?Grouping organisms according to structural similarities and differences, as well as their evolutionary histories, helps further future research.The need to consider genes and embryos when classifying is unnecessary and therefore eliminated.Scientists find a common language useful when researching living things.Having a universal, Latin scientific name helps the sharing of knowledge across the world.30s
- Q6The purpose of using scientific names allows biologists to ̶̶the scientific name includes only the family and the species namethe classification includes fewer categories than the scientific namethe scientific name includes only the genus and the species namethe classification includes multiple species names for the same organism30s
- Q7The knowledge of the species name of an organism most importantly indicates for scientists –which organisms have reproductive potential with one anotherprecisely where the organism lives in the worldthe life span of the organismthe color of external features30s
- Q8The classification of an organism is important for scientists because –it allows for an organism to have multiple namesit allows for organization of organisms based on common characteristicsit increases the chances for organisms to be misnamedit creates a historical look at the organism's ancestry30s
- Q9Which characteristic should be used to classify the horse and cow in one group and all the other organisms in another group?presence of vertebraenumber of eyespresence of hoovesnumber of legs30s
- Q10A team of scientists collected a unicellular, prokaryotic organism that lived in a volcanic hot spring and had lipids in its cell membrane that were not found in any other group of organisms. The scientists most likely classified the organism into which of the following kingdoms?FungiArchaebacteriaProtistaEubacteria30s
- Q11Biologists have found a unicellular organism and know that it is a prokaryote. To successfully classify the organism into the appropriate kingdom, the biologists would have to determine —if it has a nuclear membranethe temperature of its environmentif it can survive in the absence of oxygenthe components of its cell wall30s
- Q12Which of the following contains all of the kingdoms that have eukaryotic organisms?Archae and BacteriaAnimalia, Plantae and BacteriaAnimalia, Protista, Plantae, and FungiAnimalia, Plantae, and Protista30s
- Q13Scientists around the world use a standardized taxonomic system. Why would scientists want to use a taxonomic system that is standardized?In order to avoid confusion with the identification of organismsBecause Linnaeus established the systemSo that Latin names can be applied for a practical purposeIn order to place organisms in different groups30s
- Q14The Linnaean taxonomic system classifies organisms into divisions called taxa. If two organisms belong to the same taxonomic group, they are related. Similarity at which of these levels indicates the closest relationship?GenusClassPhylumOrder30s
- Q15The gray squirrel, Eastern fox squirrel, and red squirrel are all different species of squirrels. Why is having a scientific name for each species of an organism important? Which sample was most likely DNA?To keep the classification system from being altered as new organisms are discoveredTo prevent existing named organisms from having their names changed as they become extinctTo prevent existing named organisms from having their names changed as they become extinctTo standardize the naming and organization of organisms to avoid confusion30s
