Answer the following question given this paragraph: Another mechanism besides diffusion to passively transport materials between compartments is filtration. Unlike diffusion of a substance from where it is more concentrated to less concentrated, filtration uses a hydrostatic pressure gradient that pushes the fluidand the solutes within itfrom a higher pressure area to a lower pressure area. Filtration is an extremely important process in the body. For example, the circulatory system uses filtration to move plasma and substances across the. Q: What is used during filtration to push fluids and solutes, from higher pressure areas to lower pressure areas? Choices: - constructs pressure gradient - limited pressure gradient - magnesium pressure gradient - hydrostatic pressure gradient A:
hydrostatic pressure gradient
Answer the following question given this paragraph: Polymers are long molecules composed of chains of units called monomers. Q: What long molecules are composed of chains of units called monomers? Choices: - complexes - microbes - drummers - polymers A:
polymers
Q: Answer the following question given this paragraph: Vitamins are organic compounds that the body needs in small amounts to function properly. Humans need 16 different vitamins. Six of them are listed in Table below . Vitamin D is made in the skin when it is exposed to sunlight. Bacteria that normally live in the gut make vitamins B12 and K. All other vitamins must come from food. The table shows good food sources of the vitamins. Q: Vitamin d is made in the skin when it is exposed to what? Choices: - darkness - water - dirt - sunlight A:
A: sunlight
Question: Answer the following question given this paragraph: Bacteria are so small that they can only be seen with a microscope. When viewed under the microscope, they have three distinct shapes ( Figure below ). Bacteria can be identified and classified by their shape:. Q: How are bacteria identified and classified? Choices: - by there movement - by their color - by there cell count - by their shape A:
Answer: by their shape

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
