Keiser University Nutrition & Healthy Life Discussion

Description

Part 1

Click on Week 1 Discussion, above, then Create Thread, on the next page, to post your main response!

The Discussions are not simply statements of opinion. They are intended to allow you to expand upon and apply the principles discussed in your textbook, the lectures, and/or other research you conduct. Each week a question will be posed for your consideration. Before answering, you should review the chapters covered during this week and the lectures.

It is strongly encouraged that your initial post be posted by 11:59 PM ET on Thursday. It should be at least 250 words. This MUST be in your own words. Do NOT copy and paste from the Internet. You MAY use quotes from a source, but those quotes will NOT count towards your 250 word count requirement. Please do not plagiarize. If you use a quote, you MUST put quotation marks around it AND you MUST cite the source at the end of your post. It is NOT simply enough to put a source at the end. You should also include at least one reference in your post. Do NOT use Wikipedia or Yahoo! Answers as a source.

You should then make at least two additional posts to other students. These posts should be at least 100 words and be substantive in nature. While pleasantries such as “I agree” or “great job” are nice, they will not count as one of your required posts. Your posts should be on at least 3 separate days with all being completed by 11:59 PM ET Sunday.

Science can be defined as a systematic approach to acquiring knowledge. Science is based upon facts and evidence rather than beliefs or superstitions. To understand Biology and science, you must first examine how scientific knowledge is obtained.  Science is a process that involves several steps.  Read the description of the steps involved in the scientific method in the text paying close attention to the steps outlined in Section 1.3. Then pick one of the examples below and describe the steps of the scientific method you would use to test the question or find the solution to the problem. In other words, please design a virtual experiment (using the steps of the scientific method) to test the hypothesis you make about one of the questions listed below.

Be sure to identify the steps (observation, hypothesis, prediction, experiment/test, controls, results, conclusions). In your responses to each other, help each other identify the parts of the process properly so that the results can be clearly interpreted.

  1. Will chilling an onion before cutting it keep you from crying?
  2. If you shake up different kinds or brands of soft drinks (e.g., carbonated), will they all spew the same amount?
  3. Do all breakfast cereals that say they have 100% of the U.S. recommended daily allowance (RDA) for iron really have the same amount?
  4. Are all potato chips equally greasy (you can crush them to get uniform samples and look at the diameter of a grease spot on brown paper)? Is greasiness different if different oils are used (e.g., peanut versus soybean)?
  5. Does eating breakfast have an effect on school performance?
  6. Do the same types of mold grow on all types of bread?
  7. Does increasing the ethylene concentration ripen fruit more quickly?
  8. Can you use a household water filter to remove flavor or color from other liquids?
  9. Does the power of a microwave affect how well it makes popcorn?
  10. Can you tell/taste the difference between ground beef, chuck, and round after they have been cooked?

Remember that participation is required on a minimum of three days. You are required to respond to at least 2 classmates. 

Part 2

The Nutritional Intake Food Journal Blog assignment is worth a potential total maximum of 100 points and there are two components: (1) Nutritional Food Intake Journal (50 points maximum) and (2) Nutritional Intake Reflection Blog post (50 points maximum). Both of these components will be submitted when you post your Blog reflection.

(1) Nutritional Food Intake Journal: All three days must be completed within the Excel journal with all food, food stuffs and beverages documented with their respective nutrient composition.

NOTE: enter only the number values; no units like g (grams) are needed. The totals for each day will auto calculate at the bottom of the excel page.  Download and complete the Food Intake Journal here ~~~>  Food Intake Journal_LABELYOURFILEWITHYOURNAME.xls

(2) Nutritional Intake Reflection Blog post: a 250 word post discussing what you have learned about your eating habits and how it has impacted what and how you eat and drink and how this relates to the organic molecules of life (Chapter 3 in the text). 

To submit the Week 1 assignment, click “Create Blog Entry” in the top left corner. Title your Blog Entry “Your Name Nutritional Intake Reflection Blog” and then type your 250 word reflective blog post. The Nutritional Food Intake Journal is required to be directly uploaded as an excel file to the Submission Area for the Nutritional Intake Reflection Blog post. Post the Nutritional Intake Reflection Blog and upload your Food Intake Journal excel file to the Submission Area

Does chilling a onion before cutting keep you from crying

Discussion Topic: Does chilling a onion before cutting keep you from crying

Many people have the common problem of crying while cutting onions. Step1: My observation is that chilling an onion in the refrigerator before cutting it will prevent you from crying. Step 2: My first hypothesis is that chilling a onion in the refrigerator will slow down the enzymes preventing it from going into the air. Step 3: Chilling for thirty minuets will help with the tears that come with cutting onions (Swartz,John,2020). Step 4: The first thing I will be doing is placing a new onion into my fridge for about thirty minuets, making sure the onion is in the middle of the fridge with nothing else around it. Keeping the fridge closed all the way without opening it for the remainder of time while waiting. Step 5: Once our timer is up, I was able to cut my onion without any stinging sensation and any tears from flowing out. Step 6: By testing out my hypothesis I have concluded that without chilling the onion before cutting it, it gives the opportunity for the sulfur compound called propanethial-S-Oxide to travel into the air and be converted into sulfuric acid when in contact with water. By slowing down the enzymes in the onion before cutting, it prevents them from being able to get past the onion wall and spreading into the air therefor the it would not be able to get in contact with sulfuric acid causing our eyes to sting and tear up (Hennerman, Alice 2021). Using the essentials of biology I was able to go through the scientific method in order to get to my conclusion of the experiment.

RESPOND TO Lana Malone

Does eating breakfast have an effect on school performance?

Many people consider breakfast the most important meal of the day while others tend to skip it or make excuses such as not having enough time to have breakfast. I ate breakfast during high school, and I can attest that it showed academically as I consistently stayed in the top 10 percent of my class.

DISCUSSION TOPIC: Does eating breakfast have an effect on school performance?

OBSERVATION: Eating breakfast influences school performance and help students concentrate while taking tests.

HYPOTHESIS: Eating breakfast does influence school performance and will lead to more students excelling in school.

PREDICTION: Breakfast will improve school performance because important nutrients are derived from breakfast meals that can help increase memory and concentration.

EXPERIMENTS: Gather 24 students, 12 male and 12 female in the 10th grade. One group will not eat breakfast for two weeks and the other will. The students will all be given a 25-question math quiz at the end of the two weeks.

CONTROL: Gather another group of 12 students, all male and they will not eat breakfast for two weeks and will be tested at the same time as the test groups.

RESULTS: The 12 students who ate breakfast all scored 90% and above on their tests while the test group and control group all scored below 80% and below and struggled to concentrate while taking the test.

CONCLUSION: Breakfast is the most important meal of the day and has a huge effect on school performance. Students who eat breakfast will have a higher nutrient intake, have a faster memory recall, and better mental development. Students who don’t eat breakfast show increased error, have a difficult time paying attention resulting in lower grades. recall
