Document Summary

Microevolution: adaptive radiation (cluster of closely-related species that are each adaptively specialized to a specific habitat or food source; ex. Chromosomal translocation(chromosomal alteration that occurs if a broken segment is attached to a different, nonhomologous chromosome. ) Amish and ellis-van creveld syndrome), male competition (competition to pass on genetic traits to offspring, types: sperm, combat, infanticide. or to mate with the females, one fit male can mate with many females ex. Key to life and most abundant element in the universe. Can create chains and carbon-carbon bonds), cenozoic(age of mammals, birds, insects & plants, link=change planet, chordate fish; swimming animal), central dogma(dna contained coded information that"s transferred to rna, messenger rna used to produce protein or product of genetic code. Compact configuration of planets; instability; debris scattered(late heavy bombardment), only 1% of debris remained) , Nonpolar compound(compound made of molecules linked through chemical bonds arranged so distribution of charges are symmetrical.
