Answer:
The impulse will not be transmitted
Explanation:
The nervous system sending a signal by triggering the action potential of the cell. To trigger the action potential, a certain threshold of membrane potential has to be reached. Acethylcholine is a neurotransmitter that can change the membrane potential, and if the number if enough will trigger an action potential.
If the number of acetylcholine is not enough, there will be no action potential triggered and the signal will not be transmitted. Since the signal won't reach the muscle, then muscle contraction will not happen.

Answer:
1. Flower-The biological function of a flower is to affect reproduction, usually by providing a mechanism for the union of sperm with eggs.
2. leave-Leaves provide food and air to help a plant stay healthy and grow. Through photosynthesis, leaves turn light energy into food
3. Stem-The primary functions of the stem are to support the leaves; to conduct water and minerals to the leaves, where they can be converted into usable products by photosynthesis; and to transport these products from the leaves to other parts of the plant, including the roots
4. Roots-Root pressure, in plants, force that helps to drive fluids upward into the water-conducting vessels ( xylem )
