A drug selectively blocks Ca2+ channels at the axon terminus. The membrane potential at the terminus will:
A) increase
B) decrease
C) not change

if we change the resting membrane potential of a neruon from -70mv to -80mv, firing an action potential in that neurons would be:
a)harder
b) about the same
c)easier

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.

explanation:

okay now i don't know this but for the pints nothing else to say bye
