When a variable is continuous, p(A) equals the area under the curve corresponding to A divided by the total area under the curve.

The sign test analyzes both the magnitude and direction of the data.

These glial cells provide critical support for neurons in the form of nutrients for ATP production, reuptake of neurotransmitters from the synaptic cleft, and regulation of the ionic environment around neurons.

This particular vitamin is produced with events that begin in the skin.  When produced this vitamin increases calcium absorption of calcium in the gut.  Calcium is needed for proper nerve function, proper muscle function, and blood clotting.

Management accounting information and reports do not have to follow set principles or rules such as GAAP but should be useful to its audience and meet the cost/benefit test.

Frank has a microbial infection attacking his brain. Which cell type would you expect to proliferate and be most active during this time?

For data that are not normally distributed, the standard deviation will sometimes be negative.

Use the pull-down menus to select the best terms that make these sentences correct: Imagine a chemically-gated channel located on a neuron’s dendrites. If that channel binds an inhibitory neurotransmitter, it will allow [blank1] ions to influx OR [blank2] ions to efflux.  The resulting change in the target neuron’s membrane potential would be BEST described as a(n) [blank3].

THIS IS AN OPTIONAL BONUS QUESTION WORTH UP TO 3 EXTRA-CREDIT POINTS! Study the diagram below carefully and then read the additional information below it.  Imagine that the neuron you see above was dissected from a sea slug (Aplysia californica) and placed in a petri dish.  This neuron was then submerged in a bath that exactly replicates the normal extracellular fluid for this species, which is coincidentally exactly the same as in humans.  This neuron was then ever-so-gently impaled with two recording electrodes (orange and green triangles) placed into the axon hillock and axon terminal, respectively.  Those recording electrodes are connected to voltmeters and separate computer monitors showing that the neuron is healthy and chillin’ at its normal resting membrane potential.  There is also a stimulating electrode (blue triangle) implanted into one of the neurofibril nodes and connected to a stimulator device that is set to deliver +15 mV of current each time its ridiculously big red button is pushed. Using the text box below, answer the following questions in complete sentences and using proper grammar and capitalization: 1. Imagine that you push that big red stimulating button at exactly Time 0 on the recording screens and deliver +15 mV into the neuron at that exact site.  Will an action potential occur at that site?  Explain why or why not in as much detail as you can muster. 2. What would you expect to observe over the next 50 milliseconds on the green computer screen?  Explain your reasoning in as much detail as you can muster. 3.  What would you expect to observe over the next 50 milliseconds on the orange computer screen?  Explain your reasoning in as much detail as you can muster.
