Answer the following question given this paragraph: Excretion is any process in which excess water or wastes are removed from the body. Excretion is the job of the excretory system. Besides the kidneys, other organs of excretion include the large intestine, liver, skin and lungs. Q: What is the process whereby excess water and waste is removed from the body? Choices: - filtration - diffusion - exhalation - excretion A:
excretion

Answer the following question given this paragraph: Carbohydrate Digestion The average American diet is about 50 percent carbohydrates, which may be classified according to the number of monomers they contain of simple sugars (monosaccharides and disaccharides) and/or complex sugars (polysaccharides). Glucose, galactose, and fructose are the three monosaccharides that are commonly consumed and are readily absorbed. Your digestive system is also able to break down the disaccharide sucrose (regular table sugar: glucose + fructose), lactose (milk sugar: glucose + galactose), and maltose (grain sugar: glucose + glucose), and the polysaccharides glycogen and starch (chains of monosaccharides). Your bodies do not produce enzymes that can break down most fibrous polysaccharides, such as cellulose. While indigestible polysaccharides do not provide any nutritional value, they do provide dietary fiber, which helps propel food through the alimentary canal. The chemical digestion of starches begins in the mouth and has been reviewed above. In the small intestine, pancreatic amylase does the 'heavy lifting' for starch and carbohydrate digestion (Figure 23.29). After amylases break down starch into smaller fragments, the brush border enzyme -dextrinase starts working on dextrin, breaking off one glucose unit at a time. Three brush border enzymes hydrolyze sucrose, lactose, and maltose into monosaccharides. Sucrase splits sucrose into one molecule of fructose and one molecule of glucose; maltase breaks down maltose and maltotriose into two and three glucose molecules, respectively; and lactase breaks down lactose into one molecule of glucose and one molecule of galactose. Insufficient lactase can lead to lactose intolerance. Q: Making ups about 50 percent of the modern american diet, what food group can be classified according to the number of monomers they contain of simple sugars and/or complex sugars? Choices: - proteins - fats - grains - carbohydrates A:
carbohydrates

Answer the following question given this paragraph: USDA, photo by Scott Bauer. Deer ticks are the vectors for Lyme disease . public domain. Q: Deer ticks are the vectors for what disease that affects humans? Choices: - dengue fever - ringworm - malaria - lyme disease A:
lyme disease

Answer the following question given this paragraph: When chemicals in solution react, the proper way of writing the chemical formulas of the dissolved ionic compounds is in terms of the dissociated ions, not the complete ionic formula. A complete ionic equation is a chemical equation in which the dissolved ionic compounds are written as separated ions. Solubility rules are very useful in determining which ionic compounds are dissolved and which are not. For example, when NaCl(aq) reacts with AgNO3(aq) in a double-replacement reaction to precipitate AgCl(s) and form NaNO3(aq), the complete ionic equation includes NaCl, AgNO3, and NaNO3 written as separated ions:. Q: A complete ionic equation is a chemical equation in which the dissolved ionic compounds are written as what? Choices: - charged ions - joined ions - realized ions - separated ions A:
separated ions
