difference between determination and differentiation determination: commitment to a specific cell lineage (morphogens promote development down a specific cell line) differentiation: refers to changes a cell undergoes due to selective transcription to take on characteristics appropriate to its cell line 47. difference between disruptive v stabilizing v directional selection disruptive: selection against the mean, so with the two extremes stabilizing: selection for the mean directional: selection for one extreme 48. difference between ELISA, centrifugation, northern blotting, eastern, and western and southern blotting ELISA: isolates one specific protein northern: detect RNA southern: detect DNA centrifugation: isolates prtoeins but not specifically western: detects specific proteins eastern: analyze post translational modifications (part of western) 49. Difference between fetal and adult circulatory system Fetal has foramen ovals, which connects the right to left atrium Ductus arteriosus, connects pulmonary artery to the aorta Ductus venosus connects the umbilical vein to the inferior vena cava 50. Difference between ganglia and nuclei Ganglia- nerve cluster in PNS, nuclei- nerve cluster in CNS 51. difference between gangliosides and sphingomyelins all gangliosides have an on oligosaccharide as a head group, while not all sphingomyelins do 52. difference between gastric glands cells mucous cells: produce basic solution chief cells: secrete pepsinogen parietal cells: secrete HCl solution 53. difference between GLUT2 and GLT4 transporters GLUT2: activity is high when the blood and liver has high concentrations of glucose, and then it the transporter puts glucose in those places anyway against the gradient GLUT4: same concept but for adipose and skeletal muscle 54. Difference between gram+ and gram- bacteria + have a thick cell wall composed of peptidoglycan and lipoteichoic acid -thin cell wall with peptioglycan but also phospholipids and lipopolusaccharides

55. difference between granulocytes and agranulocytes the two types of leukocytes, and 56. difference between group I and II introns and regular introns I: can be excised int he complete absence of any proteins II: can self splice regular: need sNRPs 57. difference between heterochromatin and euchromatin heterochromatin: not transcribed, tightly packed, stains darkly euchromatin is the opposite 58. difference between horizontal and vertical gene transfer Horizontal gene transfer: the transfer of genes from one organism to another not through reproduction Vertical gene transfer: transfer of genes through reproduction (binary fission for bacteria) 59. difference between hydrostatic and osmotic pressure hydrostatic is the pressure of the actual fluid in a blood vessel osmotic is the pressure of drawing water to solutes 60.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
