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

Astudent analyzed ears of corn that demonstrated two traits in the f2 kernels, purple or white colors and smooth on wrinkled shapes. a tabulation of 135 individual kernels gave the following results: purple and smooth = 75 white and smooth = 28 purple and wrinkled = 24 white and wrinkled = 8 what would be the only phenotype present in the f1 ger
