a) strength b) voltage c) circumference d) speed 8. (1pt) Myelination increases the _ of an action potential. (1pt) After an action potential passes what resets the membrane potential to its resting -70mV? a) voltage-gated Na+ channels b) voltage-gated K+ channels c) Na+/K+ pump d) G-protien-coupled receptors 7. (1pt) What is the threshold voltage for firing an action potential? a) -55mV b) +50mV c) -70mV d) -60mV 6. First, _ summation is the effect of neurotransmitters binding at dendritic receptor sites over time and second, _ summation is the combined effects of neurotransmitters binding to different locations on the membrane. (1pt) There are two ways multiple presynaptic action potentials are combined to affect whether a postsynaptic neuron. (1pt) An autoreceptor is sensitive to the neurotransmitter released by a) its own neuron. Describe one way these postsynaptic receptors can create an IPSP at the postsynaptic neuron and one way they can create an EPSP at the postsynaptic neuron. HOMEWORK 1 ANSWERS HOMEWORK 2 Due in class at Midterm 2 Tuesday, Feb 18 HOMEWORK 2 ANSWERS HOMEWORK 3 For 1.25 extra credit, due in class at Final Tuesday, March 17. (2pts) After an action potential neurotransmitters are released into the synaptic cleft and bind to postsynaptic receptors. HOMEWORK 1 Due in class at Midterm 1 Tuesday, Jan 28. Then label the line(s) with the appropriate letter. If the event extends over a period, use two lines to mark the start and end. For each event, draw a vertical line in the figure to mark the event. (3pts) Label the diagram with the following key events of an action potential: a) absolute refractory period, b) relative refractory period, c) Na+ channels open, Na+ channels close, d) K+ channels open, e) Na+/K+ pump restores resting potential. It's been a while since I took the class so I don't really remember much, but definitely enough to get a basic grasp of the topics.Name: _ Cogs 17, Quiz C Total out of 10 points 1. If you memorize everything as though it is linear it will be harder to recall the info you need on the exam, since the questions are not in the order we were taught. So the calculation of Cost of Goods Sold using COGS formula is as below. Also, try to mix up the order as you memorize. As COGS is calculated using only direct costs, we should ignore the indirect costs related to these products. Also use the homework to study! i folded back the definitions and would try to recite them by looking only at the concept, then do the same thing but cover concept/match to definition. Rewrite them, and while you dont need to memorize the minute details, definitely know the bigger concepts by heart. slides are good if you have trouble with comprehension/understanding a topic but ultimately you should be memorizing the notes for the exam. What you should do is allocate the notes into digestible sections and try to memorize each part at a time. Therefore the business has to sell at the break-even price of at and above 11567 per customer order to sustain and to recover over the costs. What I remember helped me was to draw out diagrams/flow charts for the sensory systems. 30000 Fixed costs 50000 variable costs 10000 units 8 cost per unit. After you go through a decent amount of information (like, one side of a page of notes), try to go through each concept and see if you can recite the information. I did horribly on midterm 3 my answers were at least 50 RNG. Fill in the blanks of what you missed in a different color so it stands out. Copy the notes, then try to replicate them by memory on a separate paper. Rewrite them, and while you don't need to memorize the minute details, definitely know the bigger concepts by heart. 'To inspire and nurture the human spiritone person, one cup, and one neighborhood at a time.' The core values of the mission statement reflect Starbucks dedication towards its customers experience and satisfaction, company goals, and its focus on positively impacting communities around the world. What you should do is allocate the notes into digestible sections and try to memorize each part at a time. I did flashcards for my first midterm but didn't have time for the second midterm and still turned out fine. I crammed the notes three hours before my second midterm and got the same score as I did on the first midterm, which i studied for for 2 weeks. From someone who took this course last year and passed with an A:ĭon't waste your time on slides.
