In terms of classification of organisms, it can be said that the living things on Earth are very A. dangerous B. deceptive C. developed D. diverse. The next lower level of classification, immediately following phylum is A. kingdom B. order C. class D. species. The next higher level of classification, immediately following family is A. species B. genus C. class D. order. Human beings are called Homo sapies; here, “Homo” represents A. genus B. species C. class D. kingdom. Organisms belonging to the same species usually interbreed with one another. Exceptions to this can be found in some A. reptiles B. mammals C. plants D. vertebrates
A scientist is attempting to a cladogram that shows the evolutionary closeness of three organisms in relation to humansAfter doing DNA analysis, they that the organisms share the following percentages of DNA Organism A and humans share 85% of their DNA Organismn and humans share 80% of their DNA Organism and humans share 90% of their DNA Based on informationwhich order should they go on the cladogram ( related to most related ?
Select the reason why is the morphospecies concept problematic for scientists,1. All of the above2. This concept allows scientists to define too many species because it is entirely subjective3. You can get cryptic species that look too similar to identify4. Genetic information might reveal that there are more or fewer species than what the morphology of the organisms implies
1. Which describes the modern classification system?a. based on evolutionary relationshipsb. called Linnean classificationc. based on similar appearancesd. called Darwinian classification2. If two organisms are in the same clade, what can you predict about theirrelationship?a. They are not closely related.b. They share a common ancestor.c. They compete for resources.d. One organism evolved into the other organism. 3.Which best describes traditional classification?a. It is based on shared characteristics.b. It is based on evolutionary relationships.c. It is called phylogenetic classification.d. It is called cladistics
1.What is the scientific name of the beluga whale? 2.Write the common name of another species that is in the same CLASS as the beluga whale. 3.Bees and bats both fly, and their wings would be considered: A.Analogous Traits B.Homologous Traits
Each is an essential operation of classification except _________________.1. crossing organisms in question for data2. describing related groups3. fitting groups into a formal hierarchy4. naming groups5. cladistic
1. Gradualism is the theory that the earth’s features are the result of long-term processes that continue to operate in the present as they did in the past. TRUE or FALSE 2. Malthus explained the fossil record as the result of a succession of catastrophes followed by new creation events. True or false? 3. Taxonomy is the branch of science concerned with the rules of classifying organisms based on evolutionary relationships. * true or false?
Which of the following describes systematics?a. studies evolutionary relationshipsb. includes taxonomy and classificationc. includes phylogenetic treesd. utilizes fossil, morphological, and molecular datae. All of these are correct.
4Scientists should only use derived traits to construct phylogenies because many fossil species retain only derived traits. derived traits are under greater genetic control than are analogous and homologous traits. all organisms have homologous traits. analogous and homologous traits do not tell us anything about close phylogenetic relationships.
