Answer:
Epinephrine binds to receptors on some smooth muscles (ex: around arterioles) → Ca++ released from ER → intracellular Ca++ up → stimulates contraction. c.

Answer:
An orange peel in a trash will start to decompose.
- The carbon atoms will be released into the air as a result of decomposition.
- These carbon atoms will be converted into carbon dioxide in the atmosphere.
- Plants will take in this carbon dioxide for making food by the process of photosynthesis.
- When animals will consume the pants, the carbon products will be accumulated int he body of the animals. Some of the carbon will be converted into carbon dioxide in the animals and will pass out of the animal's body through respiration.
