Define BMI

/in /by

Part 1

Define BMI: You must define BMI, though not just with a general definition indicating its relationship to height and weight. Please also do not forget to define the actual term BMI!

Part 2

Calculate BMI: Many students use an automated calculator to complete this part of the assignment. I will deduct points if I do not see the actual math calculations. Please include all stages of the math calculations associated with determining your BMI.

Part 3

Compare/Contrast BMI & Individual Plan: There are three sections to this part of the assignment, and for the first part, you need to designate where your BMI falls according to the standard tables (underweight, normal, overweight, obese). In the second part of the assignment, you need to develop a dietary plan for your BMI value, and for the most part, you need to be as detailed as possible. Basically, I would like to see a “day in your life” according to where your current BMI falls. You need to include how many calories you plan on taking in and why, and you also need to develop a day’s worth of eating with specific foods and portions. As far as the exercise plan, again, you need to be as specific as possible. The goal of this section is to develop a plan that incorporates all of the components of a sound fitness program (flexibility, endurance, strength training, body fat, and cardiovascular), as well as discuss specific exercises that you plan on doing. Basically, the goal is to produce a weekly plan, with specific exercises, that has all of the components of a sound fitness plan.

Part II: Applying Science to Everyday Life

Recently, Earl attended a picnic at his daughter’s school. The picnic was a potluck, and the food was served outdoors. Contributions included hamburgers, hot dogs, baked beans, potato chips, potato salad, coleslaw, apple pie, and vanilla ice cream. Within 24 hours of the picnic, several attendees developed symptoms of food poisoning. Of the 50 people who attended the picnic, only 30 people became ill. Every person at the picnic ate something, but not every person had an opportunity to sample each item. Earl noticed that the potato salad he started to eat was warm. He also noticed that his hamburger was somewhat pink in the middle and not fully cooked. Earl wonders if eating the hamburgers or the potato salad could be responsible for making some attendees ill. Earl has begun to apply the scientific method to this common problem. Complete each of the following tasks in 200 to 300 words. 

  1. How would the scientific method help Earl create an experiment to determine which food sources made people sick?

  2. Describe the steps of the scientific method Earl utilized.

  3. Describe the remaining steps Earl will use if he decides to use the scientific method to determine what made the people sick.

Salmonella typhimurinSalmonella typhimurium is a Gram-negative, rod-shaped bacteriumg lactose negative, citrate positive, lysine decarboxylase positive, gelatin hydrolysis negative, and the production of hydrogen sulfide
Escherichia coliGram-negative, rod-shaped bacterium that causes.motilefacultative anaerobes (they can makes ATP energy by aerobic respiration if oxygen is present, but is also capable of switching to fermentation)
Clostridium perfringensClostridium perfringens is a Gram-positive, spore-forming, heat-resistant, rod-shaped anaerobic bacterium, widely distributed in soil, marine sediment, decaying vegetation, and the intestinal tract of insects, humans and other vertebrates. The toxin is a zinc metallophospholipase that requires zinc for activation.

Alcaligenes faecalis. It was originally named for its first discovery infeces, but was later found to be much more common in other places as well. Optimum growth occurs at about 37°C with nopigmentation. Whileopportunistic infections do occur, thebacterium is generally considered non-pathogenic. When an opportunistic infection does occur, it is usually observed in the form of a urinary tract infectionGram-negative, rod-shaped, motile, non-nitrate reducing, oxidase positive, catalase positive, alpha hemolytic, and citrate positive(variable)obligate aerobe that is commonly found in the environment

Shigella sonnei1).Shigella are closely related toEscherichia coli andSalmonella and share common antigens with one another and other enteric bacteria. There are four species ofShigella:S. boydii, S. dysenteriae, S. flexneri,
and S. sonnei.Shigella is a genus of bacteria belonging to the family Enterobacteriaceae. Species of this genus are Gram-negative, rod-shaped, and non-lactose fermenting (with exception toS. sonnei). They are also non-motile due to the lack of flagella and makes ATP (an energy molecule) by aerobic respiration if oxygen is present, but is also capable of switching to fermentation –facultative anaerobe.Shigella species can ferment carbohydrates with the production of acid, and grow in translucent white colonies (Figure
Bacillus cereusSome strains are harmful to humans and causefoodborne illness, while other strains can be beneficial asprobiotics for animals.[1] It is the cause of “Fried Rice Syndrome,” as the bacteria is classically contracted from fried rice dishes that have been sitting at room temperature for hours (such as at abuffet).[2Bacillus cereus is anendemic, soil-dwelling, Gram-positive, rod-shaped, beta hemolyticbacterium.

Helicobacter pylori(Figure 1). The species name stems from:Helico, meaning helical or spiral shape,bacter, meaning bacteria, andpylori, refering to pylorus region of the stomach. This pathogen possesses five to seven distinct flagella and grows best when cultured at 37°C (Figure 2). Interestingly, in resting individuals, 37°C is the stomach’s temperature – the targeted organ; however, the bacteria is able to withstand temperatures as low as 25°C.Helicobacter pylori is a Gram-negative, curved S-shaped bacterium, which also has a non-cultural coccoid form with rounded ends

What topic are you going to write your review on?

/in /by

Historical summary–This is here you begin working on your mini-review. What topic are you going to write your review on? Find an example of an early peer reviewed original researcharticle that helped shape this field. Looking at review articles and the dates of papers they cite isone way to begin unraveling this thread. The Davis book will also be excellent for providingbackground into this area. I will provide an example for you to see. Write a one-page summarydescribing this experiment, the findings, the importance and how this work was received into thescientific community. I’ve had questions about “how old” historical means–it depends on thefield. Some areas such as vaccination have roots that go back to the 1800’s, other areas such asthe immune-neuro connection have developed just over the last 10 years. The date of thehistorical article should be representative of the beginnings of the field you have chosen to research.
