BSC2011L Final Review TA Kate Section 1 7 The Final Exam will be the last week of class next week NOT finals week The final exam is 10 of your grade The Final Paper is due next week online and hard copy it is 15 of your grade Student Survey Quiz 6 Introduction Feedback Strengths Writing a clear hypothesis presenting a clear question Huge improvement in selecting appropriate studies to reference in their paper the studies seem relevant to your work and they re from scientific journals Areas for Growth Keep it general to start Insect oviposition Add transitions and explanations to your previous studies and background info so that we can anticipate the types of questions you ll be asking avoid talking about a tangential study and then presenting your question immediately after Citations they should be easy points Ovipositioning isn t a word you can use oviposition or oviposit Exemplar Opening Paragraph Oviposition can be affected by numerous factors including plant type predators and density Also the type of insect which is laying the eggs has its own particular affinity for a suitable location in order to procure a more optimal survival rate for its unborn offspring By altering different factors that affect a particular species distribution of eggs the individual relationship between certain insect characteristics and survival become very apparent Exemplar Opening Paragraph One thing that makes phytophagous insects so interesting to study is the host specificity of each species Phytophagous insects have the largest amount of resources available to them since they feed at the bottom of the food chain Because of the abundance of resources available these resources are divided up among species resulting in each species having different preferences of host plants on which to feed and lay their eggs Jaenike 1990 In many phytophagous insect species the immature larvae have little to no opportunity to change the location of their development Mayhew 1997 Such is the case in the phytophagous bean beetle Callosobruchus maculatus Bean beetles lay their eggs on the seeds of host plants Unit 1 The Nature of Science Science is the investigation of rational concepts that can be tested using observation and experimentation Science advances by disproof of incorrect hypotheses All scientific investigation requires some sort of measurement or quantification of observations Unit 1 The Nature of Science A scientific method is a formal way of asking and answering questions Experiment a test of a hypothesis Hypothesis a proposed explanation for a phenomenon Unit 1 The Nature of Science Important concepts in measuring Bias vs error Other sources of error How do you deal with it Outliers Independent vs dependent variables Outlier Unit 1 The Nature of Science Model Systems There are a large number of model systems used by biologists Each study system is typically useful for specific research goals For example Mice Human Disease Guppy Evolution Fruitfly Animal Genetics Planaria Regeneration Development Guppy Poecilia reticulata Unit 2 Development and Genetics Unit 2 Development and Genetics Genetic Terms Locus physical location of a gene e g ap apterous locus Allele version variant of a gene ap ap Genotype combination of alleles at one or more loci Phenotype Trait morphology behavior molecule etc Homozygous having two copies of the same allele e g ap ap Heterozygous having two different alleles at a locus e g ap ap Dominant an allele whose phenotype is expressed in a heterozygote e g ap ap flies have normal wings Recessive an allele whose phenotype is not expressed in a heterozgyote ap is recessive Unit 2 Development and Genetics White is dominant All have white eyes Gametes Gametes W W W W W W W W W W W W W W W W W W W W W W W W white eyes red eyes Unit 3 Evolution Unit 3 Evolution TERMINOLOGY Taxa Root Nodes Branches Sister Taxa Unit 3 Evolution Using phenotypic traits can be tricky when building a phylogeny Convergent evolution Trait bias Use of molecular data solves many of these issues Unit 4 Ecology Ecology is the study of interactions between organisms and their environment This includes the study of Predator Prey dynamics Competition between among species Competition within a species Species distribution Interactions with between species and the abiotic habitat Plant insect interactions Questions REMEMBER Final Paper is due during lab next week 15 of your grade more than your final
