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 number would fall within the neuron’s relative refractory period?      

In which area of the graph do you see a sudden rush of sodium ions into the neuron?

Graded potentials could be generated in which part of the neuron?

All axons in the PNS are myelinated.

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

In which structure are sensory cell bodies located?        

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?  

One of the major adaptations of plants is alternation of generations.  Examine the figure included and choose the best answer regarding alternation of generations. 

If a base pair in the DNA sequence is altered, the protein generated is an altered protein that may result in a different phenotype.  For example, the normal phenotype is a cat with brown fur.  When the DNA sequence is altered, the altered phenotype is a cat with white fur.  What kind of agent of change is this an example of?
