Answer the following question given this paragraph: Both the increase in pressure and the decrease in temperature cause the volume of the gas sample to decrease. Since both changes are relatively small, the volume does not decrease dramatically. Q: If a gas in a closed area experiences increases in pressure and decreases in temperatures, what other attribute of the gas will be affected? Choices: - gravity - velocity - temperature - volume A:
volume
Answer the following question given this paragraph: Protein Structure. Primary protein structure is the sequence of amino acids in a single polypeptide. Secondary protein structure refers to internal shapes, such as alpha helices and beta pleated sheets, that a single polypeptide takes on due to bonds between atoms in different parts of the polypeptide. Tertiary protein structure is the overall three-dimensional shape of a protein consisting of one polypeptide. Quaternary protein structure is the shape of a protein consisting of two or more polypeptides. For a brief animation of protein structure, see www. stolaf. edu/people/giannini/flashanimat/proteins/protein%20structure. swf . Q: A sequence of amino acids in single polypeptide is the primary structure for what? Choices: - lipids - cells - dna - proteins A:
proteins

Answer the following question given this paragraph: Nutrients the body needs in relatively large amounts are called macronutrients . They include carbohydrates, proteins, lipids, and water. All macronutrients except water can be used by the body for energy. (The energy in food is measured in a unit called a Calorie . ) The exact amount of each macronutrient that an individual needs depends on many factors, including gender and age. Recommended daily intakes by teens of three macronutrients are shown in Table below . Based on your gender and age, how many grams of proteins should you eat each day?. Q: What are nutrients the body needs in relatively large amounts called? Choices: - adulterants - abundances - vitamins - macronutrients A:
**Answer**
macronutrients
