Answer:
And for some of us, what we are really saying is, “I feel lonely, all the time, ... 'I don't feel like anyone values my input', this can immediately give Ok, so you don't like where you are currently living? If you can't learn to appreciate the place that you live in, moving location will only be a done all of the above and now I appreciate the unique beauty of my location and what it has to offer. Some people love the new experiences – so getting out is often close to ideal.
Explanation:
is this right
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).
Actions that society takes collectively to ensure that the conditions in which people can be healthy can occur are defined as public health.
<h3>What is public health?</h3><h3> </h3>
Public health is the promotion and protection of the health of people and the communities where they reside, work, learn and play.
A doctor is able to treat people who are sick, and those who are working in public health. They try to prevent people from sickness or injury. Public health also promotes wellness through the encouragement of healthy behaviors.
Conducting scientific research for education about health, the people in the field of public health keep working to assure that the conditions for people are healthy. This also means vaccinating children and adults the prevention the spread of disease. It can also mean educating people about the various risks of alcohol and tobacco.
Therefore, actions that society takes collectively to ensure that the conditions in which people can be healthy can occur are defined as public health.
