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)...

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...

___ 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...

Alternation of generations - Cycle has BOTH multicellular haploid & multicellular diploid forms Are the most visible life stages of the land plant groups sporophytes (2n) or gametophytes (n)? - All are sporophyte except nonvascular is gametophyte Changing-environment hypothesis - offspring that are genetic clones of their parents are unlikely to thrive if the environment changes Crossing over - homologous chromosomes exchange genetic information Diploid dominant life cycle - Similar to ani...

hemizygous - Describes an individual who has only one member of a chromosome pair or chromosome segment rather than the usual two. In bees, males are haploid and females are diploid - True Haploid - An organism or cell having only one complete set of chromosomes. Diploid - an organism or cell having two sets of chromosomes or twice the haploid number pleiotropy - when a single gene causes multiple phenotypes or affects multiple traits. gene flow - Movement of alleles into or out o...
