EVE 100 Exam Study Questions With Answers. These study questions are meant to help you prepare for the exams. These, and questions given in the homework, are the sorts of questions that you can expect to see. Indeed, many of these questions are old exam questions. Your answers should not to be handed in and no key will be posted. If you have questions come to see your TAs or instructor during office hours or try asking your peers for help in the Chat Room on SmartSite. These questions DO NO...

hemizygous - Describes an individual who has only one member of a chromosome pair or chromosome segment rather than the usual two. In bees, males are haploid and females are diploid - True Haploid - An organism or cell having only one complete set of chromosomes. Diploid - an organism or cell having two sets of chromosomes or twice the haploid number pleiotropy - when a single gene causes multiple phenotypes or affects multiple traits. gene flow - Movement of alleles into or out o...

homology - Answer- characters present in organisms because they were inherited from a common ancestor homoplasy - Answer- two structures with the same morphology, where this morphology was not inherited from a common ancestor (evolved multiple times independently) Conflict vs Congruence - Answer- whether or not new data correlates with the hypothesized phylogeny (congruence) or doesn't correlate with the hypothesized phylogeny (conflict) Cladograms - Answer- branch lengths are meaningl...

homology - ANSWERsimilarity due to common ancestry - phenotype properties homoplasy (convergence) - ANSWERsimilarity due to independent evolution. Adaptations due to an environment. The mammal Humpback Whale and the fish Whale Shark both have dorsal fins - not because of any common ancestry. phylogeny - ANSWERfamily tree among species - hypothesis of evolutionary relationships. evolution - ANSWERchange in the heritable properties of a population over generations. Individuals DO NOT evol...

EVE 100 MT1 Practice Questions With Answers Latest Updated 2023/2024. Explain two distinct reasons why the fossil record is necessarily a biased and incomplete record of life on Earth. 1. geographical and geological biases – e.g. volcanoes 2. Taxonomic biases - timing 3. Temporal biases – oceanic vs land organisms 2. List one piece of evidence from the fossil record that shows that evolution is a gradual process with many intermediate types. 1.Gradual evolution of morphology of flatfi...

A good definition of phenotype is... - ️️the observed traits of an organism A monophyletic group (also called a clade) is defined as - ️️The set of species derived from one common ancestor A mutation in DNA found in which type of cell would be found in descendants as well as the individual in which the mutation occurred? - ️️a germ-like cell in an elephant's reproductive tract A mutation of one gene that affects cartilage metabolism can result in achondroplaia, which greatly redu...

Name an opportunity of visualizing animal behavior You can visually depict subtle postural states You can clearly show experimental design Name a challenge for visualizing behavior Motion as static for 2d graph/paper - hard to show motion on a piece of paper that is 2D Chances of misinterpretation of what is presented Name the four Tinberg questions explaining behavior and define each Mechanism - mechanisms responsible for behavior Development - ontogeny shaping behavior (learning) Function - ...

The theory of evolution by natural selection does NOT assume that: A) populations produce more offspring than can be supported in most environments. B) traits within a population vary. C) some traits that give individuals an advantage within their environment are heritable. D) individuals with advantageous traits will evolve to have higher fitness, making the trait more common over time. - Answer-D) individuals with advantageous traits will evolve to have higher fitness, making the trait m...
