Answer: Sprinters who run with prosthetic legs run in the outside lanes. They can't choose to run in the races above 200-400 meters because that is their capacity. They can't run above that speed because the prosthetics won't allow them to do the same
Explanation:
Do some crunches
make sure you are eating protein after every work out
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).
When did you post this i have been trying to find the dates these questions have been asked
Plant protein supply the body with dietary fibers and can meet the needs of almost all of the human body. but yeah its True.
