difference between totipotent, pluripotent, and multipotent cells totipotent: able to differentiate into all cell types pluripotent: able to differentiate into all three of the germ layers multipotent: able to differentiate only into a specific subset of cell types 77. Difference between transformation, conjugation, transduction, and transposons Transformation: new genetic material integrated into a genome Conjugation: the transfer of genetic material through a conjugation bridge Transduction: the transfer of genetic material through a bacteriophage vector Transposing: genetic elements that can alone insert or remove into a genome 78. difference between tropic and direct hormones tropic: require and intermediary to act direct: secreted and then act directly on target tissue 79. difference between troponin and tropomyosin tropomyosin: coils around actin troponin attaches tropomyosin to actin when tropomyosin is tight, it blocks myosin from doing a muscle contraction high calcium->makes troponin conf change of troponin and allows tropomyosin to loosen up 80. Difference between white and grey matter White: myelinated axons (deeper in brain) Grey: unmyelinated cell body's and dendrites (deeper in spinal cord) 81. Does mass number or atomic number change in the following decays: alpha beta gamma alpha: lowers mass numbers in multiples of 2, and lowers atomic number beta: raises atomic number gamma: both stays the same 82. Does the myelin sheath have an affect on action potential voltage? No, it only makes it faster, allows for nodes of Ranvier, and saltatory conduction. The magnitude of the potential is not changed 83. during saponifcation triacylglycerols undergo ester hydrolysis 84. effects of reduced intravascular volume increased HR hypotension decreased urine volume dry mucous membranes vasoconstriction 85. electrophoresis set up positively charged molecules will move towards the NEGATIVE cathode 86. enlarged nucleoli are a sign of what cancer 87. erythrocytes hemolyze when placed in distilled water because distilled water has a lower osmotic pressure than the erythrocytes intracellular contents 88. excess ADH leads to increased collecting duct permeability to water and elevated blood pressure 89. Excitatory signals trigger ___ of the neuron and inhibitory trigger ___ Exciting: depolarization Inhibitory: hyperpolarization 90. fat soluble molecules have receptors where and why in the nucleus, because fat soluble moleculs can diffuse through the cell membrane and nuclear membrane 91. functions of the lymphatic system removal of excess fluid from interstitial spaces, absorption of its from the gastrointestinal tract, removing and destruction of foreign particles 92.

    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.
