DQ 4: Hot Waters

** This is a good point in the semester to discuss making your responses a reflection of your own understanding. It is very tempting to use the copy and paste functions to glean information from your sources into your responses. Directly copying and pasting information is plagiarism. You must be able to put the information in to your own words, so that it shows that you understand the concepts. Blatant copying and pasting will result in a zero for the assignment. **
Discussion Question 4: Hot springs are one manifestation of the heat inside the earth, and of how water circulates fairly deeply in the earth’s crust. They area also sites where microbial extremophiles live – one-celled organisms that survive harsh conditions. They also can be interesting and pleasant places to visit. Using search engines, or library sources, or your own experience, find and report on the following information on a specific hot or warm spring. Put the name of your hot spring in the title of your post.
1) Name of the Hot Spring.
2) Geographic location.
3) Temperature of springs.
4) Nearby associated geologic feature (e.g. volcano, fault, mountains, etc).
5) Other interesting characteristics such as the amount of flow, or unique life associated with the hot spring.
6) Your sources of information.
7) Why did you choose to report on this particular hot spring or geyser?
Once a specific hot spring has been named and described in the discussion board, it is off limits, and subsequent entries for that hot spring will not receive points. I think as the class accumulates this information you will be surprised at how many hot springs there are. Geologic associations should also become clear.
DQ 5: Earth-Sun Interactions

One can learn a lot from looking at the earth from above. In Lecture 7, we discussed how various materials reflect or absorb solar radiation differently. Now it’s your turn! Find an aerial or satellite image of some part of the world on the web, other than those depicted in lecture. Make sure it is an image. (Not a map!) A great variety of sources exist including Google maps (satellite view). Each student should have a unique image. Copy or save the image and include it in your response. The image can be directly uploaded to Canvas, or it can be saved in a Word document. For your assignment, complete the following tasks:
1) Describe in words the geographic location covered by the image. What state, country, etc are you in? What is the latitude, longitude, and elevation? Describe the climate and/or ecosystem are you in (i.e. are you in the mountains? Desert? Urban areas? Wetland?).
2) Make a list of the various earth materials that are reflecting light differently. See Lecture 7b for several examples of this. List out which components in your image have high albedo (high reflectivity) and which ones have low albedo (low reflectivity).
3) Which materials might give off the most energy in infrared at night, and why?
4) Discuss which of these materials and albedos can change over time. Consider a time frame of a) over the course of a year, b) over several decades or centuries d) geologic time (hundreds of thousands to millions of years).
Note: Sometimes it is difficult to determine what features are from the air. Feel free to also look at pictures taken on the ground level to figure out all the features in your area. Google map view and Google street view are great for this!
To help your classmates out, post the location name of your area in the title of your response so that others will know what has already been chosen.

I have listed below TWO video links underneath the questions that need to be watched along with some readings.. Also, I attached more readings that need to be read. The 5 questions below need to come STRAIGHT from the readings and videos I have provided!
1. Which of the stats in the video was most surprising to you and why? Look up the current info for that stat and report it in your answer. WITH a resource. Web link is fine.
2. What would a bottom-heavy population pyramid tell you about the future of a particular country?
3.What problems can high population densities create in nature?
4.Why are human survivorship curves a Type I?
5. What’s a cohort?

Watch this documentary film. Title of Film: Kiss the Ground Location: https://kissthegroundmovie.com/for-schools/ (Links to an external site.) Then write a short essay (500 words minimum to 600 words maximum) that answers the following questions: What is the primary issue addressed in the film and why is it important? (50 points maximum) What is a second issue addressed in the film, and why is it important? (50 points maximum) What is a third issue addressed in the film, and why is it important? (50 points maximum) You can draft your assignment using whatever word processor you choose. Please spell check and also check for grammatical errors before posting your essay in Canvas.

1.Vital signs include things like our heart rate, blood pressure, body temperature, etc. (Readings for Unit 1; Learning Experiences 2.2a-2.2d)
a.How do we know when a “sign” (e.g., a number or observation) is a healthy sign?
b.How do we know when it is an unhealthy sign?
c.Which Learning Experience(s) in Unit 2 relate to each vital sign you studied in Unit 1 and why?
2. What is hmeostasis? (Mader 2004; Miller 2021)
3.When do our vital signs indicate that we are unable to maintain homeostasis? Why? (Mader 2004; Miller 2021)
4.You will be asked to create diagrams of gas balance (oxygen and carbon dioxide), electrolyte balance (sodium and potassium), temperature regulation, sugar regulation, and blood pressure regulation. What did you learn from the assigned readings that could help build diagrams/models of each type of regulation? (Mader 2004; Miller 2021)
5.For all Science Talks. Record three (3) big wondering questions sparked by, and related to, the assigned readings. (Examples of big, wondering questions are: Why are humans biased? Where did cells come from, Why is the sky blue? Where do dogs come from, Does the universe end? Etc.)
I am not sure if the readings are included in the file I provided, if not, please look over it online.

First of all… ALL of the answers to the two questions below needs to come straight from the images I have attached in the files!! No where else!! ONLY USE INFORMATION FROM IMAGES ATTACHED BELOW PLEASE!
1. Tell me about the Law of Superposition and how it can help explain the (ancient) natural history of Alabama. How does this affect the geological structures, biodiversity, and economy of Alabama today? Use at least 4 sentences. Good ones.
2. What characteristics of Alabama make it such a biodiverse place? Use one of our “highest biodiversity” groups to illustrate your point (freshwater snails, fish, turtles, crayfish, mussels.)

This is for an interdisciplinary science class. I need 3 topics and one of the topics I would like for it to be somewhere around the lines of short term effects of Ozempic (can be more thorough with a deeper topic just about this)… then I just need you to come up with two more topics and answer the questions in the directions I have provided in the links.. all three topics will need an outline. The sources need to come from the Univeristy of Alabama Library. If you have any more questions just message me. The other two topics I would like something along the lines of excercise and tanning beds.

Read the assigned readings (again, textbook is optional) and also view the video linked here: Nightwatch New Orleans. What attributes or components of EMS (as listed in assigned reading from the Executive Summary of the EMS Agenda for the Future) are displayed and how so (be specific)? Which ones are missing? Make sure that you list all of the components. Did anything you learned about EMS this week surprise you?

What are the main differences between prokaryotic and eukaryotic cells, and how do these differences impact microbial life?
Explain the process of bacterial conjugation and its significance in microbial genetics.
Describe the structure and function of bacterial cell walls. How do antibiotics like penicillin target bacterial cell walls?
What is the significance of plasmids in microbial genetics? How do they contribute to bacterial antibiotic resistance?
Discuss the mechanisms by which bacteria acquire antibiotic resistance genes. How does horizontal gene transfer play a role in this process?
Compare and contrast the modes of action of bacteriostatic and bactericidal antibiotics.
Explain the concept of microbial pathogenesis. What are the main virulence factors that contribute to microbial pathogenicity?
Discuss the role of biofilms in microbial communities. How do biofilms contribute to microbial resistance to antibiotics and host immune responses?
