The E zone portion of the protein
Explanation:
The glucagon hormone which is a signal molecules that triggers a reaction in the liver cells is most likely to bind to the E zone extracellular portion of the G-protein-coupled receptor. This then changes the conformation of the receptor activating the heteromeric G proteins.

Answer:
Option A 400 individuals
Explanation:
Using this formula, we can estimate the population size of the canvas backs as this is a capture-recapture method.
N = (MxC) / R
Where N = estimated Number of individuals in the population
M = number of individuals captured and Marked = 200
C = total number Captured the second time (with and without a mark) = 200 and 
R= number of individuals Recaptured (those with a mark) = 100
Thus, we have 
N = (MxC) / R
 = (200 x 200) / 100
 = (40,000) / 100
 = 400 individuals.
