 After reading chapters 11 and 12 of the McLaughlin & McLaughlin text, what set of values identified in the chapter would you consider important to any national health policy? Do we meet your set of values currently and if not, how do we get there? In your opinion, what is the value of life? How does it compare to the Christian worldview? How does it compare to other cultures and worldviews?
Your thread is due by 11:59 p.m. (ET) on Thursday, and your three replies are due by 11:59 p.m. (ET) on Saturday.
I need one Main Post (Minimum 400 words) and three Responses (200-250 Words each)
Below are the specific requirements for each part of this assignment.
THREADS:
· Must be at least 400 words.
· A minimum of one source is required (course textbook may be used).
· Citations used should be formatted in APA.
· Should thoroughly address the topic prompt, using citations as appropriate.
REPLIES:
· Must post at least three 200–250-word replies to your classmates/instructor per forum.
· Should expand upon ideas expressed in your classmates’ threads by adding new ideas to points that you agree with and/or explaining areas of disagreement.
· Should be posted intermittently throughout the forum.  Do not complete all of the replies at one time; instead, allow for conversation to develop by posting multiple times throughout the week.
· A minimum of one source per reply is required (course textbook may be used).
· Citations used should be formatted in APA.
I have attached the Discussion Rubic as to how the Main post and Responses would be Graded. Please follow every single Instruction. There is a Video attachment too that NEEDS TO BE USED doing the work
I have also attached the Main post of two students and one for instructor you need to respond to. Please send me the main post as well as the responses

Requirement from Instructor:
This week I have posted my final thoughts on our current state of affairs within the area of Health Care Policy and hope you will take the opportunity to read and comment. It is OK to disagree as well. Remember that a response to my post counts in your three responses, so please engage, as you feel directed.

What term is used to describe a neuron that is not transmitting a signal?

Passing a signal from one neuron to another – Chemical synapse


If the nervous system is going to function properly, neurons must be able to communicate with each other by passing signals to one another. This occurs at a synapse, or relay point between two cells. The most common type of synapse in the nervous system of animals is chemical synapse. Chemical synapse occurs in the narrow space between the axon terminal of the sending neuron and the dendrite of the receiving neuron.

Revised 10/19/2011

When action potential reaches the axon terminal, it is converted into a chemical signal. This chemical signal comes in the form of a neurotransmitter (a chemical that carries information from one nerve cell to another). Once the action potential arrives at the end of the neuron, it stimulates vesicles containing a neurotransmitter. The vesicle will then fuse with the cell membrane and release the neurotransmitter into the synaptic cleft using the process of exocytosis. The released neurotransmitters diffuse across the synaptic cleft and bind to receptor molecules, which are proteins attached to ion channels within the membrane of the receiving cell. The binding of the neurotransmitters to the receptor molecules causes the ion channels to open, allowing Na+ to diffuse into the cell. This influx of Na+ ions causes an action potential in the receiving neuron. The neurotransmitter is then either broken down or transported back to the sending neuron to be reused. The absence of neurotransmitters in the synaptic cleft causes the ion channels to close and the signal to end.

Analysis Questions Directions: Answer question based on readings


1. What term is used to describe a neuron that is not transmitting a signal?

2. Describe the conditions inside and outside of a neuron during resting potential.

3. Describe the conditions inside and outside of a neuron during action potential.

4. What causes a neuron to change from resting potential to action potential?

5. What causes a neuron to return to a resting potential from an action potential?
6. How is a signal transmitted through a single neuron?

7. What is a neurotransmitter?

8. How are neurotransmitters secreted into the synaptic cleft?

9. How does a neurotransmitter cause an action potential in a receiving neuron?
10. How is the signal between neurons stop?

How did eradication of Rinderpest from East Africa increase both the tree and giraffe populations in the Serengeti?

(1) Trophic Cascades in theSerengeti. Watch Dr. Cox’s video on “What Rinderpest eradication taught us about the Serengeti”, which can be found in the Instructor Insights folder for this week. Then address the following questions: (a) How did eradication of Rinderpest from East Africa increase both the tree and giraffe populations in the Serengeti? (b) How did eradication of Rinderpest from East Africa increase the population of predator species in the Serengeti? (c) What does this tell us about ecosystems?
  • (2) Shrinking Red Knots. Read two of the following three articles: Briggs (2016); Dussault (2016); Zimmer (2016). (A) In your own words summarize the basic story that the articles have in common. (B) Of the two articles you read, which of them do you prefer? Why?
  • (3) Biomes. The term “biome” is described in the textbook. For this topic, describe the biome where you grew up (or where you currently live). Identify your location, the biome of the region, and describe the major characteristics of that biome. Add enough detail and commentary from your own experience, so that your answer is 125 words or more. If you’re really ambitious, you could consider looking up the “ecoregion”. The EPA maintains information about that.

Human culture is changing faster than humans can evolve

Sexual selection is a specific form of natural selection that states that some individuals in a population are more reproductively successful than others. The theory goes on to discuss traits that occur in individuals that don’t really offer increased survivability, but seemingly are in place for the sole purpose of attracting a mate. A male peacock’s bright feathers and horns of a male ibex are examples of these sexual traits.
Can you think of other examples? Do humans display any of these characteristics? 50 words count

One major change in our environment, as compared to most of human history, is our access to food! I think of how easy it is for me to run to the grocery store and pick up food shipped here from all over the world. It has not always been such a simple and common thing to enjoy the produce of other continents. Our “food environment” has, in a way, expanded beyond our immediate geographic location, and so our access to more varied nutrient sources is heightened. We also have abundant access to junk food! So, there is great opportunity for the emergence of both wonderfully healthy populations and woefully disease-ridden populations.
