Document Summary
Bio 201 final review: laws vs. theories, laws: the rules, happens with regularity, consistent patterns, theories: explanations to the rules, well-substantiated explanation, pattern vs. Competition (-,-), commensalism (+,0), amensalism (0,-: masting: a tree produces a ton of acorns and squirrels cannot eat them all, allows some to survive and continue growth, plant defenses: secondary chemicals, thorns, spines, interspecific vs. intraspecific competition. Intraspecific: among individuals in same species: interspecific: among individuals of different species. The silk in the developing cob is the female part. By wind, pollen from the tassel is brought to the silk. Source = organs that produce more sugars than they require. Symmetry = radial or bilateral: body cavity structure = acoelomate, pseudocoelomate, Leeches: lack tentacles, coelom not divided, suckers: mollusk: foot, visceral mass, mantle, often molt shell. Nematodes: unsegmented, multilayered cuticle for gas and nutrient exchange, matures in 3 days so is used for genetics and developmental biology studies ix.
