Vocabulary for Chapter 24 and 25 of Campbell Reece Biology 8th Edition for AP Biology.

129136679	Reproductive Isolation	Existence of Biological Factors that impede members of two species from interbreeding	0
129136680	Prezygotic Barriers	Before the Zygote Prevents Fertilization	1
129136681	Habitat Isolation	When species do not encounter one another	2
129136682	Temporal Isolation	When species mate or flower during different seasons or at different times of the day	3
129136683	Behavioral Isolation	When a species does not recognize another species as a mating partner due to differences in courtship rituals, mating songs, pheromones, etc.	4
129136684	Mechanical Isolation	When male and female genitalia are structurally incompatible	5
129136685	Gametic Isolation	When male gametes do not survive in the environment of the female gametes, or when female gametes do not recognize male gametes	6
129136686	Post-zygotic Barriers	After the Zygote Prevents a hybrid zygote from developing into a viable, fertile adult	7
129136687	Hybrid In-viability	When a zygote fails to develop properly and dies before reaching reproductive maturity	8
129136688	Hybrid Sterility	When hybrids become functional adults, but are reproductively sterile	9
129136689	Hybrid Breakdown	When hybrids produce offspring that have reduced viability or fertility	10
129136690	Allopatric Speciation	When a population is divided by geographic barriers so that interbreeding between the two populations is prevented. If the two gene pools diverge sufficiently, a new species can form	11
129136691	Adaptive Radiation	Emergence of numerous species from a common ancestor	12
129136692	Sympatric Isolation	Subdividing a gene pool when members of the daughter species are not geographically separated	13
129136693	Earth Formed	4.5 billion years	14
129136694	Miller-Urey Experiment	Simulated early Earth atmosphere, produced organic compounds	15
129136695	Protobionts	The precursors of cells; organic molecules enclosed in a membrane	16
129136696	Endosymbiotic Theory	Mitochondria and Chloroplasts contain their own DNA, ribosomes, reproduce independently of their host cell in a manner similar to binary fission, have two phospholipid bilayers, and Chloroplast thylakoid membranes resemble photosynthetic membranes of cyanobacteria	17
