  • Eco & Evol 100The key event in the formation of a new speciationEvolution of reproductive barriers

  • Eco & Evol 200A speciation event where geographic separation is the initial block to gene flowAllopatric speciation

  • Eco & Evol 300A definition of a species based on the ability of individuals to successfully mate and reproduce Biological species concept

  • Eco & Evol 400A possible result of competition where one species goes locally extinctCompetitive exclusion

  • Eco & Evol 500A population growth pattern that occurs when a population grows rapidly at first but then reaches a carrying capacityLogistic Growth

  • Diversity 100The Kingdom that used to include all unicellular eukaryotes but now includes some multicellular onesKingdom Protista

  • Diversity 200The thins threads that make up the vegetative body of a fungushyphae

  • Diversity 300The diploid phase of a plants life cycleSporophyte (and the zygote)

  • Diversity 400The name given to animals that have a true body cavity, located within mesoderm tissuecoelomates

  • Diversity 500Along with a notochord, pharyngeal slits and a post-anal tail, it is one of the 4 common characteristics of the Phylum ChordataDorsal hollow nerve cord

  • Reproduction & Development 100Another name for asexual reproduction in plantsVegetative reproduction

  • Reproduction & Development 200When the sperm and the egg unite outside of the females bodyExternal fertilization

  • Reproduction & Development 300A series of rapid cell divisions that occurs after fertilization in animalscleavage

  • Reproduction & Development 400The stage in vertebrate development where the three germ layers form in the embryogastrulation

  • Reproduction & Development 500The stage in vertebrate development where the structure that becomes the spinal cord formsneurulation

  • Nutrition 100A saclike gut with only one openingGastrovascular cavity

  • Nutrition 200The organ where most chemical digestion takes place in the digestive system of vertebratesSmall intestine

  • Nutrition 300A flow-through gut with a mouth and an anusAlimentary canal

  • Nutrition 400An adaptation common to all structures that are used for absorption of nutrients in various organismsIncreased surface area

  • Nutrition 500The three most important nutrients that plants must get from soil and the common components of fertilizersNitrogen, phosphorous & potassium

  • Gas Exchange 100The respiratory system commonly found in aquatic organismsgills

  • Gas Exchange 200The respiratory medium that makes ventilation harderwater

  • Gas Exchange 300The respiratory system of insectsTracheal tubes

  • Gas Exchange 400The method that mammals use to ventilate their lungsNegative pressure breathing

  • Gas Exchange 500The process that increases the efficiency of gas exchange in the gills of fishCountercurrent exchange

  • Transport 100The name of the system of tubes that transport water and dissolved nutrients throughout a plantxylem

  • Transport 200The name of the system of tubes that carry sap from sugar source to sugar sinkphloem

  • Transport 300The main mechanism that causes water to move up from the roots to the tips of a plantTranspiration/cohesion

  • Transport 400The movement of fluid due to pressure differences, as occurs in the phloem of a plantMass flow or bulk flow

  • Transport 500The waxy coating of the endodermis that forces water and dissolved materials to pass through a cell before entering the vascular cylinder of a plantCasparian strip

  • Circulation 100A circulatory system where the fluid is always enclosed with blood vesselsClosed circulatory system

  • Circulation 200The number of chambers in the heart of an amphibianthree

  • Circulation 300The number of capillary beds a red blood cell would pass through in a mammal from when it leaves the heart to when it returns to the heartone

  • Circulation 400The chamber in the heart of mammals that pumps blood through the systemic circuitLeft ventricle

  • Circulation 500Known as the pacemaker of the heart, this is the node that initiates the signal that causes the heart to beatSinoatrial node

  • Osmoregulation & Excretion 100The vertebrate organs where urine is producedkidneys

  • Osmoregulation & Excretion 200The nitrogenous waste that is the most efficient to excrete and is excreted by marine invertebratesammonia

  • Osmoregulation & Excretion 300The portion of the nephron that is responsible for water reabsorptionLoop of Henle

  • Osmoregulation & Excretion 400The hormone that is produced when the blood concentration or osmolality increases and your body needs to conserve waterADH Anti-Diuretic Hormone

  • Osmoregulation & Excretion 500The excretory organs of insectsMalpighian Tubules
