2 types of lateral meristems: - Cork cambium vascular cambium 2 ways to increase allele diversity/allele frequency distribution: - 1.) gene flow 2.) mutation 3 criteria for designating species: Boys Make Pasta - biological, morphological, phylogenetic Adventitious Root Systems - Roots that emerge from the stem just above ground to help support plants in shallow soils Allopatric Speciation - Separated by some physical barrier Annuals - Angiosperm plants that die off at the end of each yea...

Taxonomic hierarchy - a system of classifying and naming species for the purpose of understanding and establishing relatedness between species or larger groupings Kingdom Phylum Class Order Family Genus Species What words are used to name the individual type of organism? - Genus and Species Super and Sub prefixes - used to further describe refinement of groupings above and below a certain level 3 criteria for designating species: Boys Make Pasta - biological, morphological, phylogen...

What is systematics? - Answer Study of biological diversity and the evolutionary relationships among organisms, both extinct and modern What is Taxonomy? - Answer Science of describing, naming, and classifying living and extinct organisms and viruses What are the 8 categories of taxonomic hierarchy (in order from species upward to broader classifications)? - Answer Species, Genus, Family, Order, Class, Phylum, Kingdom, Domain Who is the scientist that proposed the current two-p...

adventituous root - emerges from the stem right above the ground to help support plants in shallow soils allopatric speciation - occurs when subpopulations are separated by some physical barrier. The two subpopulations remain reproductively isolated (no gene flow) and, over time, diverge from each other Angiosperms - Vascular plants with fruit-covered seeds The fruit increases the protection and dispersal of seeds; the largest number of species of all plants. 1. Flower: a major innovation...

The common ancestor of primates and raccoons DID have five-digit hands, but that ancestral mammal's hands WERE NOT modified for complex digital manipulation. Therefore, the presence of hands in primates and raccoons is an example of ___________ but the presence of complex manipulative ability is an example of ___________. A. Genetic drift ... Gene flow B. Convergence ... Homology C. Mutation ... Cladistics D. Homology ... Convergence E. Macroevolution ... Microevolution Homology ... Convergence...

Adaptation - A trait that helps an organism survive and reproduce adventitious roots - roots that arise above ground Alleles - Different forms of a gene allopatric speciation - the process of speciation that occurs with geographic isolation Aneuploidy - Abnormal number of chromosomes. Archea - have cell walls that, do not contain peptidoglycan assotative mating - an individual is more likely to mate with another that is similar in phenotype to itself autosomal inheritance - Inheritance o...

Contrivance - an adaptation that is a result of the modification of a previous ancestor Adaptation - A trait that helps an organism survive and reproduce Exaptation - evolutionary adaptation of an existing structure for a completely new purpose Vestigial Trait - A trait inherited from a common ancestor but is no longer used dipliod cell - cell that has 2 copies of each chromosome, one from egg, one from sperm (46) Hapliod - having a single set of unpaired chromosomes, one egg (23)...
