Put the following spinal nerve structures in order of most proximal to most distal from the spinal cord.

An action potential arrives at the bottom of the purple neuron and nothing happens; 5 minutes later an action potential arrives at the bottom of the black neuron just as another action potential arrives at the bottom the purple neuron 1 msec later and the orange neuron sends an action potential.  This is an example of:  

Which type of neuron is found in the greatest amounts in the nervous system?

Damage to which structure would stop the transmission of sensory information but not motor informtion from this spinal nerve?

If neurotransmitters are released from the black neuron that cause the orange cell’s potential to go from resting to -62 mV, what kind of channels were opened?

What is occurring in the area between #2 and #3?

We have been working on our allelopathy project this semester.  We also discussed allelopathy in small groups and in our lecture class.  Discuss allelopathy and it’s importance to our communities.  In your discussion, tell me what allelopathy is, it’s mechanism, why it is important to study allelopathy, and how we can use allelopathy to make our communities better.  This is a great opportunity to show me vocabulary you learned in our allelopathy lecture (such as transpiration, leaching, allelochemicals, and so many more words) .

The gene pool includes the following genotypes and phenotypes: BB (black fur), Bb (black fur), bb (white fur).  Recall that the genotypic equation is: p2 + 2pq + q2 = 1 If p = 0.7, what is the genotypic frequency of Bb?  

Animals with two germ layers are _________ while animals with three germ layers are _____________
