Together, the Dietary Guidelines for Americans 2010 point the way toward longer, healthier, and more active lives. These key recommendations, along with additional recommendations for specific population groups, appear throughout the text as their subjects are discussed. By law, the Dietary Guidelines for Americans are reviewed and revised as needed every five years. Each edition shares some similarities with previous editions but also sets precedent in new ways. Perhaps most noteworthy to the 2010 edition is Pla Diet Planning Principles and Guidelines Chapter 2 Section 2.1 Directions: Read section 2.1 of Chapter 2 on pgs 35-40. Answer Questions below. 1. A 3 ounce lean t-bone steak contains 0.09 mg of the nutrient thiamin and has 174 kcalories of energy. A half of a cup of fresh cooked broccoli contains 0.05 mg of thiamin and has 27 kcalories of energy. a. Calculate the thiamin nutrient density for both the steak and the broccoli. Which has a higher thiamin nutrient density? (3) b. Is the nutrient density of thiamin the only thing to take into consideration when making a decision to eat the steak or the broccoli? Explain your thinking. (2) 2. The key recommendations of the Dietary Guidelines for Americans 2010 are clustered into 4 major topic areas. Describe each area and provide a summary of the guidelines for EACH area. (15) prevent and/or reduce overweight and obesity through improved eating and Physical activity behaviors Control total Kcaloric intake to manage body weight for people Who are over tight or obesity

The diagram below represents a hydra as viewed with a compound light microscope. * If the hydra moves toward the right of the slide preparation, which diagram best represents what will be observed through the microscope? 1) 3) Why is this a preferred procedure? 1) The coverslip will prevent the slide from breaking. 2) The organisms will be more evenly distributed. 3) The possibility of breaking the coverslip is reduced. 4) The possibility of trapping air bubbles is reduced. 7. A cell in the field of view of a compound light microscope is shown in the diagram below. 2) 4) In which direction should the slide be moved to center this cell in the microscopic field? 1) to the right and up 3) to the left and up 2) to the right and down 4) to the left and down The diagram at the right represents a strand of algae viewed under the low-power objective of this microscope. Under the high-power objective, how would this same slide appear? 1) 3) 8. Which structure in a stained cheek cell would most likely be visible when viewed through the high-power objective of a compound light microscope? 1) cell wall 3) chloroplast 2) ribosome 4) nucleolus TUU 2) 4) 9.A wet-mount slide preparation of a specimen is stained in order to 1) eliminate some organelles 2) make cell structures more visible 3) use the high-power lens 4) remove water from the slid ☺ _10. A coverslip should be used for preparing a 1) frog for dissection 2) solution of iodine for food testing 3) wet mount of elodea (a simple plant) 4) test to determine the pH of a solution 13. A student views some cheek cells under low power, Before switching to high power, the student should 1) adjust the eyepiece 2) center the image being viewed 3) remove the slide from the stage 4) remove the coverslip
