BIO 1100 Columbia Southern Human Body Diseases & Regulations Questions
Question 1 It is illegal in the United States to pay for a transplant organ, and doctors cannot perform the operation unless the patient is at the top of the official list. However, some wealthy people in need of a kidney transplant go overseas to other countries where the laws do not address the issue. Suppose a wealthy person finds a poor person willing to sell his or her kidney and purchases the kidney. If you or a loved one needed an organ and could afford to go overseas, would you do this? Why, or why not? What do you think would be the impact of this transaction on the donor? Your journal entry must be at least 200 words in length. No references or citations are necessary. Question2 In the mid-1950s, the first study linking cigarette smoking to lung cancer was published. In the decades that followed, many other studies supported this finding and a host of other health-related effects attributed to smoking were uncovered. Over the last few decades, cities and states have created local regulations prohibiting smoking in certain public places. In 2009, the U.S. Food and Drug Administration was given regulatory authority of all tobacco products. Chapter 20 of your textbook begins with a comparison of two sources of inhalable nicotine: traditional tobacco cigarettes and E-cigarettes. Because E-cigarettes are a relatively new technology, less is known about the long-term effects of the firsthand and secondhand inhalation of vaping products. However, in recent years they have been treated and regulated similarly to traditional cigarettes. Your assignment for this unit is to create a 10- to 12-slide PowerPoint presentation that covers the following elements: the anatomy and physiology of respiration (e.g., explain how breathing works); the effects of the inhalation of smoke and E-cigarette vapor on gas exchange in the lungs; specific diseases associated with smoking, both pulmonary and cardiovascular; and lastly, based on what you know about E-cigarettes from the reading and your own research, defend or oppose the regulation of vaping products as traditional cigarettes. You will need to cite and reference at least one article from the CSU Library databases as one of your sources of information. CSU Library Database Instructions Open the CSU Online Library link in your student portal. Under "discovery search," click the tab for "articles."" In the keyword search field, type keyword "vaping" and/or "E-cigarette" to find articles that cover this topic. You may get different results doing separate searches for each keyword. The keywords "electronic cigarette" may also be used. From the list of available articles that comes up, select one that interests you. Click on the article link, then click on "PDF full text or HTML full text," and read the article. (Note: Not all articles will provide the full text; if your choice does not, you will have to select a different article.) Discuss what you learned from your chosen articles in 1-2 slides in your presentation. Cite the article according to APA guidelines, and list it on your references slide. PowerPoint slides should not contain a lot of text; use speaker notes to provide the details of your presentation. The general practice is to use no more than 5-6 bullet points per slide. The quality and depth of your speaker's notes will be significantly factored into your grade. Title and reference slides should be included. These do not count toward the 10- to 12-slide requirement. In addition to providing references on a reference slide, you need to cite your material in the slides as appropriate; use APA format for your references and citations. Suggestions for Searching for Illustrations Use at least 3 images in the presentation. When looking for illustrations to use, it is suggested that you type the subject into a search engine and click "images." For your presentation, you are allowed to copy and paste images (being sure to cite and reference them). However, you are NOT allowed to copy and paste content, such as text, tables, and the like. As much as possible, your presentation needs to be in your own words. PowerPoint Guidance Do you need to refresh your knowledge concerning PowerPoint? Review this tutorial on PowerPoint Basics. Click on the Notes tab on the right side of the tutorial screen to see a transcript of the PowerPoint webinar. You can also search online for information concerning best practices about what should and should not be done when creating a PowerPoint presentation. Notes: As directed in the tutorial above, pay attention to the background and font colors in your presentation—try to avoid using plain black text on a white background, but also avoid using colors that are visually difficult to see (such as yellow text on a light background) or that are unpleasant (such as red text on a yellow background). Strive for a pleasing, visually appealing appearance. Reminder: The speaker notes should provide the detail and discussion of your presentation, and everything in the presentation should be in your own words, not copied and pasted from a source. Question 3 Some people like to read books, while others like to watch or play sports. Clearly, everyone prefers some activities over others. Why do you think this is? Consider choices you make concerning your own entertainment. Why do you like to do the things you do? Why does it feel good to you to do them while they might not appeal as much to someone else? Do genetics play a part in your decisions? Your journal entry must be at least 200 words in length. No references or citations are necessary Question 4 Imagine that you are a forensic detective and you have been tasked with analyzing a complete skeleton. How might you go about determining if the skeleton is male or female? What characteristics would you look for? Your answer must be at least 200 words in length. Question 5 Discuss the difference between general senses and special senses. Then, of the special senses, decide which you think is either most important or least important and explain your position. Your answer must be at least 200 words in length.

As you continue with your study of
physics, you'll learn that there are four fundamental interactions in
nature. These interactions are
summarized in this table:

So gravity is one of the four fundamental
forces of nature. We will learn about
the other three in Physics II. Some interesting things to note about the
gravitational force:
·
In a relative
sense, it is the weakest of the four fundamental interactions. Even so, gravity is largely responsible for
the dynamics of our solar system, galaxy, and the Universe as a whole.
·
Gravity acts over
an infinite distance. Objects may be
separated by thousands of light years, but they experience gravitational
attraction.
·
Gravitational
interactions obey the inverse-square law.
·
Coulomb's Law
dictating the force between two charged particles is also an inverse-square
relationship.
In this lab, you will perform experiments
that illuminate the concept of gravitational interaction.
This activity is based on Lab 10 of the
eScience Lab kit.
Our lab consists of two main
components. These components are
described in detail in the eScience manual.
Here is a quick overview:
Experiment 1: In the first part of the lab, you will subject
a variety of objects to the force of gravity and discuss your
observations.
Experiment 2: In the second part of the lab, you will use a
flashlight as an analogy to demonstrate the inverse-square law of gravity.
Take detailed
notes as you perform the experiment and fill out the sections below. This document serves as your lab report. Please include detailed descriptions of your
experimental methods and observations.

Based on your
results from the experiments, please answer the following questions:
Experiment
1: Falling in a Gravitational Field
The
following expression for the acceleration due to gravity works well for
objects near the Earth’s surface (G is the gravitational constant, Me
is the mass of the Earth, and Re is the radius of the Earth):
Use the
above equation to calculate the gravitational acceleration at an altitude
of 100,000 meters above the Earth. By what percentage is this acceleration
different from that on the Earth's surface?
How
does air resistance alter the way we perceive falling objects?
Using the universal law of gravitation, show that the
gravitational acceleration experienced by an object is independent of its
mass.
Experiment
2: Inverse Square Law

Diameter of light circle
Radius of light circle
Area of light circle
NOTE: Be sure to specify your units.
1.
How
did the intensity (brightness) of the circle of light seem to changes as you
increased the source distance?
2.
How
did the area of the circle of light change as you moved farther away? How does
this relate to the gravity field of a body?
3.
Make
a plot of distance vs. area for the light shining from the cup to the wall
(plot the area data on the y‐axis).
4.
Draw
a line of best fit through your data points, and comment on the general shape
of your plot. What kind of relationship
does this indicate (i.e. linear, exponential, logarithmic, etc.)?
5.
If
the amount of light shining from the flashlight is constant, the intensity of
light should decrease as the area it shines on gets larger. Using your plot from
question 2, sketch an approximate plot for light intensity vs. distance.
6.
If
you moved too far away from the wall the circle of light probably became very
difficult to see. Is the intensity of the light circle ever zero? Is it correct
to say that gravity doesn’t exist between objects on opposite sides of the
galaxy?
