Answer the following question given this paragraph: Matter typically exists in one of three states: solid, liquid, or gas. The state of a given substance is a physical property. Some substances exist as gases at room temperature (such as oxygen and carbon dioxide), while others (like water and mercury metal) exist as liquids. Most metals exist as solids at room temperature. All substances can exist in any of these three states. Q: Most metals exist in which form at room temperature? Choices: - gases - liquids - oils - solids A:
solids
Answer the following question given this paragraph: Dialysis Technician Dialysis is a medical process of removing wastes and excess water from the blood by diffusion and ultrafiltration. When kidney function fails, dialysis must be done to artificially rid the body of wastes and fluids. This is a vital process to keep patients alive. In some cases, the patients undergo artificial dialysis until they are eligible for a kidney transplant. In others who are not candidates for kidney transplants, dialysis is a lifelong necessity. Dialysis technicians typically work in hospitals and clinics. While some roles in this field include equipment development and maintenance, most dialysis technicians work in direct patient care. Their on-the-job duties, which typically occur under the direct supervision of a registered nurse, focus on providing dialysis treatments. This can include reviewing patient history and current condition, assessing and responding to patient needs before and during treatment, and monitoring the dialysis process. Treatment may include taking and reporting a patient's vital signs, preparing solutions and equipment to ensure accurate and sterile procedures. Q: Dialysis is a medical process of removing wastes and excess water from the blood by diffusion and ultrafiltration. when kidney function fails, dialysis must be done to artificially rid the body of this? Choices: - bile juices - mucus and phloem - calories - waste and fluids A:
waste and fluids
Q: Answer the following question given this paragraph: Visible light is part of the electromagnetic spectrum. Q: Visible light is part of what spectrum? Choices: - mechanical spectrum - eclipse spectrum - molecular spectrum - electromagnetic spectrum A:
A: electromagnetic spectrum
Question: Answer the following question given this paragraph: The embryo, which begins as a flat sheet of cells, begins to acquire a cylindrical shape through the process of embryonic folding (Figure 28.14). The embryo folds laterally and again at either end, forming a C-shape with distinct head and tail ends. The embryo envelops a portion of the yolk sac, which protrudes with the umbilical cord from what will become the abdomen. The folding essentially creates a tube, called the primitive gut, that is lined by the endoderm. The amniotic sac, which was sitting on top of the flat embryo, envelops the embryo as it folds. Q: What sac, which was sitting on top of the flat embryo, envelops the embryo as it folds? Choices: - uterus - umbilical sac - epithelial sac - amniotic sac A:
Answer: amniotic sac

Answer the following question given this paragraph: Sulfuric acid is the industrial chemical produced in greatest quantity worldwide. About 90 billion pounds are produced each year in the United States alone. Write the Lewis structure for sulfuric acid, H2SO4, which has two oxygen atoms and two OH groups bonded to the sulfur. 7.5 Strengths of Ionic and Covalent Bonds 64. Which bond in each of the following pairs of bonds is the strongest? (a) CC or C = C (b) CN or C N (c) C O or C = O (d) HF or HCl (e) CH or OH (f) CN or CO 65. Using the bond energies in Table 7.2, determine the approximate enthalpy change for each of the following reactions: (a) H 2(g) + Br 2(g) 2HBr(g) (b) CH 4(g) + I 2(g) CH 3 I(g) + HI(g) (c) C 2 H 4(g) + 3O 2(g) 2CO 2(g) + 2H 2 O(g) 66. Using the bond energies in Table 7.2, determine the approximate enthalpy change for each of the following reactions: (a) Cl 2(g) + 3F 2(g) 2ClF 3(g) (b) H 2 C = CH 2(g) + H 2(g) H 3 CCH 3(g) (c) 2C 2 H 6(g) + 7O 2(g) 4CO 2(g) + 6H 2 O(g) 67. When a molecule can form two different structures, the structure with the stronger bonds is usually the more stable form. Use bond energies to predict the correct structure of the hydroxylamine molecule:. Q: What is the industrial chemical produced in greatest quantity worldwide? Choices: - gaseous acid - liquid acid - boric acid - sulfuric acid A:
**Answer**
sulfuric acid
Answer the following question given this paragraph: Protists are classified as animal-like, plant-like, or fungus-like. The three groups differ mainly in how they obtain carbon and energy. Q: Protists are classified as animal-like, plant-like, or what else? Choices: - bacteria - like - pathogen - like - virus - like - fungus-like A:
fungus-like
