Answer:
C) Acetylcholine receptors in the motor end plate
Explanation:
Excitability is the ability of the muscle fiber to produce an electric signal in response to a stimulus. The motor end plate is the region of sarcolemma present opposite to the synaptic end bulbs. It is a muscular region with millions of integral membrane proteins serving as acetylcholine receptors.
The acetylcholine receptors are ligand-gated ion channels and acetylcholine serves as the ligand. Each of the ion channels of acetylcholine receptors is opened by binding of two molecules of acetylcholine. The opening of these ion channels allows Na+ to move across the membrane. The inflow of Na+ makes the inside of the muscle fibers more positive and triggers the firing of the action potential.

Answer:
More CO2 molecules are responsible for production of more carbohydrates.
Explanation:
Plants make their carbohydrates (food) by process called photosynthesis. CO2 is responsible for Carbon Fixation in Calvin cycle during photosynthesis. The more CO2 is utilized the more carbohydrates can be manufactured.
Thus, if plants are grown for several days in atmosphere where more 14CO2 is available as compared to 12CO2 then more food (starch-carbohydrates) production can be accomplished.
