Cocaine and amphetamine blocks the reuptake of dopamine from the synapse. This would result in A. More action potential in the post-synaptic neuron B. Dopamine staying in the synapse without any pre-synaptic nerve transmission C. All of the above D. None of the above
6. Cocaine is often called an "indirect agonist" of dopamine receptors. Why do you think this term is used? 7. If someone has a somatic mutation that affects their CYP2D6 gene (and thus drug metabolism), is that person's child likely to also have drug metabolism differences? Why?

Infants and small children have a substantially shorter ear canal. What effect would you expect this to have on their sensitivity to different frequencies? Select the correct answer The different length of ear canal should have no effect O on frequency perception because the speed of sound is the same regardless. The different length of ear canal should have no effect on frequency perception because only the resonant wavelength and not the frequency will change. Your Answet They should be...
please explain

Would you expect an amorphous piece of solid polyethylene (PE) to be isotropic or anisotropic? Briefly explain............(2 points) Briefly explain why, upon solidification, an alloy of eutectic composition forms a microstructure consisting of alternating layers of the two solid phases. What is this structure called? What kind of effect does this structure have on the melting point of the alloy and why? (5 points)
