"Salting out" - certain ions become too concentrated in soils and draw water out of roots by osmosis, causing plant death 2 types of lateral meristems: - Cork cambium vascular cambium 2 ways to increase allele diversity/allele frequency distribution: - 1.) gene flow 2.) mutation 3 Chordate Subphyla - Urochordata, Cephalochordata, and Vertebrata 3 criteria for designating species: Boys Make Pasta - biological, morphological, phylogenetic 4 key characteristics of chordates - 1.) notochor...

Cell Theory - All organisms are made of cells, and all cells come from pre-existing cells. Conclusion: If you trace a cell's lineage back far enough, you will discover that all cells are descended from a common ancestral cell Evolution - The heritable change in a population over time or a change in gene frequency in a population over a number of generations Proximate process - what happens in short term, measured in fractions of lifetimes Ultimate process - longer timeframe (lifeti...

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...

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...

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...

___ are aquatic producers that create silica shells - Diatoms ___ are pathogenic protists that can cause large skin lesions. - Leishmania ___ are producers that are responsible for half of the C fixation in marine environments. - diatom ___ are thought to be the first organisms to evolve oxygenic photosynthesis - Cyanobacteria 2 specific examples you could provide to convince your friend that these organisms are relevant and/or interesting - ecological impact and use for medical research A...

Genetic Drift - the constant changing of allele frequencies (that percentage of all alleles any one, or more, allele occupies in a population) in a population over time, due to random mating. Random Mating - has the effect of changing how frequently an allele is found in a population. GENETIC DRIFT IS RANDOM, ALWAYS DRIFTING UP AND DOWN bottlenecks - where a gene pool is significantly reduced for some reason and a relatively small allele diversity remains. Founder event/effect - a cha...

adaption - A heritable trait that increases the relative fitness of individuals having the trait. All organisms are mad of cells- cell theory - Cells are naturally occurring compartment bound by a thin, flexible plasma membrane, and contains chemicals in an aqueous solution that perform life functions All cells come from existing cells, continous cycle Alpha - The threshold allowed to for a probable similarity between the data and the null. alternative hypothesis - The hypothesis that stat...
