o For each of the 3 major macromolecules (i.e., proteins, fats, and carbohydrates) explain in your own words at least 2 functions each has in the human body, plants, or animals. (10 pts) o Compare the nutrition label for ground beef below to the nutrition label from any canned vegetable you may have in your pantry. Name your chosen vegetable and describe three differences between the two labels as they relate to macromolecules. (Note: if you do not have any canned vegetables, you may use the internet to find a label.) (10 pts) o Reflect on what you learned in this Unit about a healthy diet. Then, explain why you think beef is or is not necessary for a balanced diet. (10 pts)

Selected Answer: A. The three macronutrients are proteins, carbs, and fats. They each have a different fuction but work together to keep the body moving. Proteins promote muscle growth and regulate body tissue. Carbs provide energy to the body and stores energy. Fats are fuels the body and provide cell function. B. We eat only beans out of the can. Other vegetables and fruits we prefer fresh. After comparing the two foods, there are differences we do not think about. While both beans and burgers offer protein, the beef offered more protein. Because of the fat content in beef, it had more fat than beans. In this case, the beans are a leaner protein. The beans are starchy and offer more carbohydrates. C. I am not a big meat eater. Beef takes longer to digest and can do more harm than good. I would stick to the beans as a healthier choice. From this lesson, I would have to say that beans are healthier as they offer less fat, the carbs can be burned off, and the beans offer a leaner healthier choice of protein.

In the course of a conversation, you observe that three of your friends like horror movies. Horror movies happen to be your favorite type of movie as well. You also know that all of these friends were born in the same week that you were, even in the same year. An astrology-loving friend hypothesizes that people born in that week like horror movies more than other genres of movies. You decide to use the scientific method to test this hypothesis. Part A What should you do next? O Come up with a theory to explain why movie preference is related to birth week. O Perform experiments to test your hypothesis. O Propose several alternative hypotheses. O Refine your hypothesis. Submit Request Answer

Experiment Conclusion SCENARIO 3: Paper airplane flight A group of students notices that different paper airplane designs fly different distances, and they want to determine if wing shape affects flight distance. The students try folding paper airplanes with various wing shapes with measuring the distances each airplane flies when thrown with the same force. They feel that paper airplanes come with the same force. They feel that paper airplanes with certain wing shapes will fly farther than others due to differences in aerodynamic properties. The test out three types of paper airplanes: one with wide wings, one with narrow wings and one…
