BIO 1070- Inquiry Case 1: UNIT 1 - Zebra mussels were native to the Caspian see and the Black sea - They were most likely transported here by the ballasts tanks of liners - The zebra mussel was first discovered in 1988 in lake St. Claire. - Around the world there are over 850 different species of mussels. - Within North America there are 300 known species - There are 41 species of mussels in Ontario. Life cycle of a mussel: - Unionids perform obligate parasitism meaning that they release there eggs on another species of fish. - Males release their sperm through the exhalant siphon and the females take in the sperm with their inhalant siphon. - Fertilization is internal and the embryos developed inside sacs called the marsupium. - The embryos then mature into Glochidia and must be attached to the gills of a fish host to continue to grow. - The mantle tissue of the mussel can be in the shaoe of a smaller fish, this allows for the bigger fish to go up close and get bitten by the mussel. - At this time the mussel releases its glochidia and they attach to the gills of the host. UNIT 2: Levels of biological organization: High to low - DomainKingdomPhylum ClassOrderFamilyGenusSpecies - Domain refers to organisms with eukaryotic cells - Kingdom refers to animals - Phylum refers to vertebrates - Class refers to mammals - Order refers to Primates - Family refers to Hominidae - Genus refers to Homo - Species refers to Humans Genotype- same set of genes Phenotype- differing physical features Phenotypic Plasticity- when the same set of genes can cause differing physical features according to environmental conditions. Abundance- number of individuals Diversity- number of species Disparity- how physically different two species are Genetic Variation- difference among individuals within among a species Tree Thinking: Sister Taxa- 2 relatives from one recent ancestor The Root- Common ancestor shared by all species depicted Branches- Connections between ancestors and descendants Terminal Nodes (tips)- living species Internal Species- extinct ancestors  A clade is a section of the tree that contains both of the sister taxa, if one of the taxa was cut off it would not be a clade. UNIT 3: Natural selection: Non-random differences in survival and/or reproduction among individual entities on the basis of differences in heritable characteristics. Adaptation: 1) a characteristic that enhances the survival and/or reproduction of organisms that bear it, relative to alternative (esp
