Answer the following question given this paragraph: A photon isn't a fixed amount of energy. Instead, the amount of energy in a photon depends on the frequency of the electromagnetic wave. The frequency of a wave is the number of waves that pass a fixed point in a given amount of time, such as the number of waves per second. In waves with higher frequencies, photons have more energy. Q: The number of waves that pass a fixed point in a given amount of time is called what? Choices: - wavelength of a wave - spectroscopy of a wave - spread of a wave - frequency of a wave A:
frequency of a wave
Answer the following question given this paragraph: The blood picks up oxygen in the lungs and carries it to cells throughout the body. Q: What does blood pickup from the lungs to be carried throughout the rest of the body? Choices: - carbon - white blood cells - platelets - oxygen A:
oxygen
Q: Answer the following question given this paragraph: Lipid Digestion A healthy diet limits lipid intake to 35 percent of total calorie intake. The most common dietary lipids are triglycerides, which are made up of a glycerol molecule bound to three fatty acid chains. Small amounts of dietary cholesterol and phospholipids are also consumed. The three lipases responsible for lipid digestion are lingual lipase, gastric lipase, and pancreatic lipase. However, because the pancreas is the only consequential source of lipase, virtually all lipid digestion occurs in the small intestine. Pancreatic lipase breaks down each triglyceride into two free fatty acids and a monoglyceride. The fatty acids include both short-chain (less than 10 to 12 carbons) and long-chain fatty acids. Q: What are the most common dietary lipids? Choices: - phospholipids - diglycerides - monoglycerides - triglycerides A:
A: triglycerides
Question: Answer the following question given this paragraph: Polysaccharides are long carbohydrate molecules of repeated monomer units joined together by glycosidic bonds. A polysaccharide may contain anywhere from a few monosaccharides to several thousand monosaccharides. Polysaccharides are also called complex carbohydrates . Polysaccharides have a general formula of C x (H2O) y , where x is usually a large number between 200 and 2500. Considering that the repeating units in the polymer backbone are often six-carbon monosaccharides, the general formula can also be represented as (C 6 H 10 O 5 ) n , where 40n3000. Q: What is the term for long carbohydrate molecules of repeated monomer units joined together by glycosidic bonds? Choices: - fibres - template strands - hydrocarbons - polysaccharides A:
Answer: polysaccharides
