Falso. For example, let's choose soccer. On the field, the coach can't tell the player to pass, to kick it to number 13, or anything like that. Some decisions can be made, like whose playing. But not all decisions are made by coaches. hope this helps! Please rate brainiest answer!
Answer:
Im guessing yes
Explanation:
kind of a obvious question...
Capillaries connect arterioles and venules and enable the exchange of water, oxygen, carbon dioxide .
Answer:
Myelinated Axons; leak channels are insulated by myelin leading to less loss of current flow and better conduction velocity. Ion channels omly located at nodes of ranvier; thus signal has sultatory conduction along myelin sheaths and jumps and move much quicker
Demyelinating diseases; along locations where myelin sheaths once was current links occur and conduction slows, the signal cannot make it very far because it looses energy as it travels through the axon
Unmyelinated axon; Ion channels are sequentially placed all along axons; thus it takes longer to send signal down axon. the energy isn't leaked out, it still contains the same signal but it is simply slower. distance between voltage gated channels needs to be small enough so local current flow can depolarize the membrane.
N/B; Harder to generate action potential in demyelinating disease
axon diameter( bigger diameter= less resistance= faster current).
