Presentation Transcript

  1. Eco & Evol 100 • The key event in the formation of a new speciation • Evolution of reproductive barriers

  2. Eco & Evol 200 • A speciation event where geographic separation is the initial block to gene flow • Allopatric speciation

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

  4. Eco & Evol 400 • A possible result of competition where one species goes locally extinct • Competitive exclusion

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

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

  7. Diversity 200 • The thins threads that make up the vegetative body of a fungus • hyphae

  8. Diversity 300 • The diploid phase of a plants life cycle • Sporophyte (and the zygote)

  9. Diversity 400 • The name given to animals that have a true body cavity, located within mesoderm tissue • coelomates

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

  11. Reproduction & Development 100 • Another name for asexual reproduction in plants • Vegetative reproduction

  12. Reproduction & Development 200 • When the sperm and the egg unite outside of the female’s body • External fertilization

  13. Reproduction & Development 300 • A series of rapid cell divisions that occurs after fertilization in animals • cleavage

  14. Reproduction & Development 400 • The stage in vertebrate development where the three germ layers form in the embryo • gastrulation

  15. Reproduction & Development 500 • The stage in vertebrate development where the structure that becomes the spinal cord forms • neurulation

  16. Nutrition 100 • A sac—like gut with only one opening • Gastrovascular cavity

  17. Nutrition 200 • The organ where most chemical digestion takes place in the digestive system of vertebrates • Small intestine

  18. Nutrition 300 • A flow-through gut with a mouth and an anus • Alimentary canal

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

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

  21. Gas Exchange 100 • The respiratory system commonly found in aquatic organisms • gills

  22. Gas Exchange 200 • The respiratory medium that makes ventilation harder • water

  23. Gas Exchange 300 • The respiratory system of insects • Tracheal tubes

  24. Gas Exchange 400 • The method that mammals use to ventilate their lungs • Negative pressure breathing

  25. Gas Exchange 500 • The process that increases the efficiency of gas exchange in the gills of fish • Countercurrent exchange

  26. Transport 100 • The name of the system of tubes that transport water and dissolved nutrients throughout a plant • xylem

  27. Transport 200 • The name of the system of tubes that carry sap from sugar source to sugar sink • phloem

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

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

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

  31. Circulation 100 • A circulatory system where the fluid is always enclosed with blood vessels • Closed circulatory system

  32. Circulation 200 • The number of chambers in the heart of an amphibian • three

  33. Circulation 300 • The 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 heart • one

  34. Circulation 400 • The chamber in the heart of mammals that pumps blood through the systemic circuit • Left ventricle

  35. Circulation 500 • Known as the pacemaker of the heart, this is the node that initiates the signal that causes the heart to beat • Sinoatrial node

  36. Osmoregulation & Excretion 100 • The vertebrate organs where urine is produced • kidneys

  37. Osmoregulation & Excretion 200 • The nitrogenous waste that is the most efficient to excrete and is excreted by marine invertebrates • ammonia

  38. Osmoregulation & Excretion 300 • The portion of the nephron that is responsible for water reabsorption • Loop of Henle

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

  40. Osmoregulation & Excretion 500 • The excretory organs of insects • Malpighian Tubules
