Presentation Transcript

  1. Eco & Evol 100 • These prevent geneflow and keep two species separate or distinct from each other • Reproductive barriers or reproductive isolation

  2. Eco & Evol 200 • A definition of a species based on the ability of individuals to successfully mate and reproduce • Biological species concept

  3. Eco & Evol 300 • A speciation event where a new species forms within the range of the original species • Sympatric speciation

  4. Eco & Evol 400 • A possible result of competition where species begin to divide up the resource and utilize different parts of the resource • Resource Partitioning

  5. Eco & Evol 500 • The maximum population size that an environment can support • Carrying Capacity

  6. Diversity 100 • The names of one of the two Kingdoms that include prokaryotic organisms • Archaebacteria and Eubacteria

  7. Diversity 200 • The name given to the life cycle of plants that describes the fact that they have multicellular haploid and multicellular diploid phases • Haplodiplontic Life cycle or Alternation of generations

  8. Diversity 300 • Animals that have a notochord, pharyngeal slits, a post-anal tail and dorsal nerve cord at some point in their life • Chordates

  9. Diversity 400 • The diploid phase of a plants life cycle • Sporophyte

  10. Diversity 500 • The name given to animals that have the first opening in the embryo develop into the anus • Deuterostomes (protosomes have the first opening become the mouth)

  11. Reproduction & Development 100 • A form of reproduction that produces clones of the parent • asexual reproduction

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

  13. Reproduction & Development 500 • The first stage in vertebrate development where the cells divide to produce more, smaller cells • 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 spinal cord forms • Neurulation

  16. Nutrition 100 • The organ where most nutrients are absorbed in the digestive system of vertebrates • Small intestine

  17. Nutrition 200 • A flow-through gut with a mouth and an anus • Alimentary canal

  18. Nutrition 300 • The name given to the sac-like digestive system of Cnidarians, which have only one opening • Gastrovascular cavities

  19. Nutrition 400 • The gland that secretes buffer and enzymes into the small intestine • pancreas

  20. Nutrition 500 • A chambered stomach found in some herbivores • A ruminant stomach

  21. Gas Exchange 100 • The respiratory surface commonly found in aquatic organisms, such as fish • 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 • When the diaphragm contracts and expands the chest cavity causing air to move into the lungs of mammals • 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 stacks of dead cells that transport water and dissolved nutrients upward in 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 way a plant creates pressure differences to cause phloem sap to move • Pumping sugars in or out of phloem

  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 • The number of chambers in the heart of a frog • three

  32. Circulation 200 • A circulatory system where the circulating fluid is not always enclosed within vessels and is the same as the general body fluid • open circulatory system

  33. Circulation 300 • The cells in the blood that carry oxygen • Erythrocytes or red blood cells

  34. Circulation 400 • The name of the circuit of flow in mammals that sends oxygenated blood from the heart through the body capillaries, where it gives up the oxygen, then back to the heart • Systemic circuit

  35. Circulation 500 • The name given to the contraction phase of the cardiac cycle, where the highest blood pressure is generated • Systole

  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 ball of capillaries where filtration occurs in the kidneys • glomerulus

  41. Nervous 100 • The cells that actually conduct nerve impulses • neurons

  42. Nervous 200 • The name of the series of events that is the actual nerve impulse • Action potential

  44. Nervous 400 • The chemicals that carry the nerve impulse signal across a chemical synapse • neurotransmitters

  45. Nervous 500 • The jumping motion that describes the way a nerve impulse travels down a myelenated axon. • Saltatory conduction

  46. Systematics 100 • The evolutionary history of a group of organisms • phylogeny
