Answer:
muscles,glands
Explanation:
The part of the body that responds to the stimulus is called an effector organ. The peripheral nervous system is made up of sensory nerves that transmit impulses from the receptors in sensory organs to the central nervous system and motor nerve that transmits impulses from central nervous system to effector. The central nervous system receives and integrates impulses from the receptors and the relays them to the effector organs.
1) Long slender leaves ("needles") because:
a) They don't lose a lot of water from photorespiration b/c of low surface area
b) Snow doesn't pile into the branches and break the branches off (snow is very heavy). the needles don't catch and hold very much snow.
2) The wood is soft and bendable. Strong wind doesn't break it, because it flexes. Any snow that does manage to pile on is dropped when the wind blows, or when the weight of the snow bends the Branch down.

<span>7.33 is a bit low. Breathing rapidly gets rid of CO2 a little faster, this reduces carbonic acid in the blood and pH will increase slightly.
