Answer:
Ok so i will try my best to describe the answers:
1) a convection current is like a boiling pot of soup. the burner heats up the soup on the bottom. hot air always goes up because the molecules become more active, making them space out upward. the hot soup travels up through the center of the pot, and the cold soup up top travels down towards the edges of the pot to replace the hot soup that just moved up. the process keeps on going and going until there is no more heat, or until the burner turns off.
2&3) the sun makes everything warmer, so when the sun touches Earth's surface, it warms up the air around it. as soon as the air warms up, it goes up into the atmosphere, like the pot of soup example. then, cold air from the top moves in to replace the hot air. with so many molecules of air moving at one time, it makes gusts of wind during the movement. when it is really windy, that means that there is a lot of hot air moving up and cold air moving down. when there is no wind, that means that every molecule is where it is supposed to be, not disturbing one another.
I hope this helps :D
Answer:
5. 1. 3. 2.4 I believe it is like that
Explanation:
12)
receptor cell bodies are found in the dorsal ganglia which is F
relay cell bodies are found in the grey matter which is G
effector neuron bodies are found in the grey matter which is G
so the answer is D
13)
J is the dorsal root of the spinal nerve and contains the axons of the sensitive cells
H is the anterior root of the spinal nerve and contains the axons of the motor cells
therefore the answer is C
14)
F is the dorsal ganglion
I is the spinal nerve
hence, the answer is B
15)
first they come through the spinal nerve which is (I), then they go through the dorsal root, which is (J) then the impulses go through the grey matter(G) , they go through the anterior root(H) and finally through I
the answer is A
