The concept of natural rights which was used in the Declaration of Independence was first proposed by THOMAS JEFFERSON
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).
Answer: electric
Explanation: use electric stuff like cars
hope that helps
Answer:
sweat and vasodilation
Explanation:
Hyperthermia is when the body is too hot. (Not to be confused with hypothermia, when the body in too cold).
When we sweat, we are releasing moisture, like little bits of water, onto our skin. The water uses up heat energy from the body to evaporate. Because the body loses heat energy, it cools.
Vasodilation is when blood vessels widen. When this happens, the blood vessels are closer to the surface of the skin, allowing heat to escape through and exit the body.
Shivering and vasoconstriction would help to keep a person warm. Shivering makes the muscles on the body move, which increases heat. (Think of exercise, but on a small scale).
Vasoconstriction keeps blood vessels away from the surface of the skin.
