1. cell differentiation is involved in what kind of signaling?: mRNA
2. correspondence interference theory: it's when someone recognizes a trait/behavior of yours and
assumes other characteristics based on that one trait.
3. trypsin: lyses peptide bonds
4. adrenal medulla
vs adrenal cortex: medulla = epi, norepi (catecholamines)
cortex = cortisol and aldosterone
5. volt units: J/C
6. farad units: C/V, electric charge
7. when BP increases, what happens to pulse and urine?: both increase
8. in the urinary system, what occurs when there is high blood pressure?: high BP
more blood pushing, greater blood volume
increase urine output
9. for urine, what is the ideal composition?: no protein, just HUNK (hydrogen, urea, nitrogen,
potassium)
10. what part of the brain controls HR?: brain stem (medulla oblogata)
11. math tip for solving logs: switch sign of exponent
take exponent and add or subtract it by first number moved back a tenth
12. hydrogen bonds: donor vs acceptor: donor = H
acceptor = electronegative atom
13. columns on the periodic table have the same what?: same properties due to their valence
electrons
therefore, you can compare elements based on their column
14. fractional distillation + bubbles = ?: superheating
bubbles break surface tension and lower pressure
15. color in organic chemistry: extended pi system with alternating double bonds
d orbitals**
16. ADH: antidiuretic hormone (vasopressin)
makes collecting duct more permeable, body reabsorbs water, makes you pee and concentrates urine, BP increases
17. when you see cancer, think of ?: mutation

18. BP equation: resistance x CO
CO = HR x SV
19. vasoconstriction: narrows vessels
restricts flow
increases BP
20. what occurs when you faint?: decrease of BP, vasodilation
21. large Ka: strong acid
22. buffers: want to stay at pka = pH
23. do indicators affect reactions?: no
24. sperm is very rich in what organelle?: mitochondria
25. albumin: protein in blood; maintains the proper amount of water in the blood
26. size of eukaryotic and prokaryotic ribosomes: 80 (60 and 40) and 70 (30, 50) respectively
27. smaller ksp: lower solubility
28. big ksp: more soluble
29. when does precipitate form?: Q>Ksp
30. titration pH values: weak base, strong acid <7
weak base, weak acid = 7
strong base, weak acid > 7
31. lewis acid: accepts pair of electrons
32. lewis base: donates pair of electrons
33. bronsted acid: donates H
34. bronsted base: accepts H
35. arrhenius acid: Produces H+ ions when dissolved in water
36. arrhenius base: produces OH-
37. optics: diverging lens: DDUV = diverging, diminishing, upright, virtual
38. optics: converging and diverging lenses and mirrors: converging (inverted real): convex
lens, concave mirror
diverging: concave lens, convex mirror
39. myopia: nearsightedness
need concave lens, diverge, f-
40. hyperobia: farsighted
convex lens, converge, f+

41. basic amino acids: lysine
histidine
arginine
42. isomerase: rearrangement of atoms, moving carbons
43. thin layer chromatography: separates molecules based on polarity
44. james lange theory of emotion:
45. shacter singer theory of emotion:
46. canon bard theory of emotion: physiological reaction and the emotion are assumed to occur at the
same time
47. merkel cells: touch receptors in the skin
48. pacinian cells: vibration
49. ruffini endings: respond to stretch
50. transformation: swallowing genetic information
51. transduction: injection, requiring a virus
52. conjugation: sex pilli, F factor
53. translocation: movement of genes
54. autosomes: every other chromosomes
55. define a species: ability to produce offspring
56. gas liquid chromatography: higher BP -> more polar -> appears farther right
57. anion exchange chromatography: Negative proteins stick to positive beads, only positive proteins
go through
58. isoelectric point: pH at which positive and negative charges cancel
