Biology Exam 3 Study Guide 1 What is the DNA error rate 2 How many errors are repaired 3 How many repair enzymes are there 4 What is the trend in genome size relative to organism complexity 5 What is the trend in organism complexity relative to the number of genes they have 6 What is the trend in the complexity of organisms relative to their strands of DNA 7 What codes for one percent of our genes 8 What codes for 5 percent of genes 9 What is the most modern primate 10 What is theory of evolution 11 What replicates on their own 12 What ship did Charles Darwin travel on 13 When was the theory of Evolution written down 14 Who actually wrote about competition 15 Person Discovery Purpose 1 Darwin a Geologist who proposes principles of gradualism 2 Hutton b Says evolution occurred because of the passing on of acquired traits 16 17 18 19 20 21 22 23 24 25 26 27 28 29 Scientists don t deal with 3 Malthus c Mechanism of evolution traveled on HMS beagle 4 Lamarck d PhD student in Asia who writes Darwin about theory of evolution and Darwin gets credit 5 Alfred Russell Wallace e Economist who published essay on Principle of Population What is a theory A hypothesis is a theory so widely accepted that everyone assumes it is true What is the key in science Where do younger stratum with more recent fossils appear Older fossils What does natural selection lead to What is used to trace family lineage What group are birds a part of they deal with Who is more closely related to mammals amphibians or reptiles Making from scratch leads to no useful The same bones are What is a vestigial structure to do different things What is an example in humans of a vestigial structure Can animals digest cellulose 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 What is convergent evolution is the same function but not of the same origin is the same structure of the same evolutionary origin Flying squirrels and sugar gliders are homologous analogous both Birds and flying insects are homologous analogous both Our eyes and squid s eyes are homologous analogous both To get a new species you need 2 things What is found in layers of rock Macromicro evolution new species develop over a large amount of time Macromicro evolution evolution on a smaller scale What is the definition of evolution List the pre fertilization forms of isolation 45 List the post fertilization forms of isolation 3 Type of Selection Definition 1 Directional a Both extremes selected against 2 Stabilizing b Majorityselected against 3 Disruptive c One extreme selected against Speciation that occurs in separate geographical locations Speciation that occurs in the same geographical location but is separated by behavioral and other types of isolation What does the Hardy Weinberg equation assume 47 48 49 50 51 52 53 54 55 56 57 58 59 60 What are the 5 mechanisms of evolution What is the definition of population What is the bottle neck effect What are pheromones If an allele goes from 9 and 1 to 8 and 2 allele frequencies in the third generation what must have happened If a allele frequency is 6 what is the other allele frequency A in a population p means that an individual can rotate their ear and q means they cannot If the p value is 52 what are the values for pquot2 qquot2 and pq b if there are 372 individuals in this population what number are heterozygous What is an SNP Which species is most current on a phylogenic tree What trend does evolution tend to follow What is a clade and what does it show What are the 8 levels of organization starting at the bottom Who invented the binomial naming system Which of the following is a clade a A clear taxonomic group b Any organism descendent from the original common ancestor c All cellular based life d Descendants from a common ancestor e All of the above 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 How old is the universe How many years ago did galaxies form Where are we located in the galaxy Which planets are in the habitable zone What is needed as a solvent for life What is the order of the planets starting with the sun What is the term to describe the first living thing Who found the first building blocks of amino acids When did the quotbig whoosh occur How many years ago did the sun condense When did the earth form When was the first fossil life discovered When did cyanobacteria pump out oxygen What are hot plumes What is adaptive radiation What is punctuated equilibrium What are the three major domains What domain kingdom do humans belong to What is the big division within plants TF Sponges are animals When the big split in animals occurred what subdivisions resulted 3 on one side 2 on the other 82 What is the closet relative to humans a Insects and spiders b Squids and octopi c Sea stars and crinoids d Sponges 83 Are humans mouth first or anus first Which term describes what they are 84 natural selection is one of mechansims of evolution 85 A population at hardy Weinberg equilibrium has an allele frequency for a dominant trait of 75 What will the allele frequency for the recessive trait be 86 Hardy Weinberg assumption related to sampling error or small populations is what 87 The mechanism of evolution which applies directly to the initiation of reproduction is what 88 Darwin published the origin of species about when a 1560 b 1660 c 1760 d 1860 89 A population at HW equilibrium with a phenotypic frequency for the dominant trait of 75 will have an allele frequency for the recessive trait of what 90 List all 5 assumptions of the HW equilibrium 91 Give one piece of embryological evidence for descent to form a common ancestor 92 93 94 95 96 97 98 99 100 Structures that come rom the same body parts but often do different functions are called what A pre zygotic isolating mechanism would include New species generally come from isolation plus In a population of Koalas we find 323 are homozygous dominant for a particular gene What percent would be heterozygous for the trait What is the domain kingdom phylum class order and family for humans What is the closest primate to humans When does adaptive radiation occur What are snails a part of What letter should be used when talking about allele frequency Biology Exam 3 Study Guide Answers 1 1 in 100000 1 in 10000000000 130 no trend no trend the more complex the organism the less dense the DNA strands exons
