Answer the following question given this paragraph: The plasma membranes of cells that specialize in absorption are folded into fingerlike projections called microvilli (singular = microvillus). This folding increases the surface area of the plasma membrane. Such cells are typically found lining the small intestine, the organ that absorbs nutrients from digested food. This is an excellent example of form matching the function of a structure. People with celiac disease have an immune response to gluten, which is a protein found in wheat, barley, and rye. The immune response damages microvilli, and thus, afflicted individuals cannot absorb nutrients. This leads to malnutrition, cramping, and diarrhea. Patients suffering from celiac disease must follow a gluten-free diet. Q: People with celiac disease have an immune response to what, which ultimately leads to malnutrition, cramping, and diarrhea? Choices: - fish - lactose - seeds - gluten A:
gluten
Answer the following question given this paragraph: Q: If citrate accumulates in mitochondria, some of it passes into where and inhibits phosphofructokinase? Choices: - Golgi apparatus - epidermis - pores - cytosol A:
cytosol
Q: Answer the following question given this paragraph: Pulmonary circulation is the part of the circulatory system that carries blood between the heart and lungs (the term "pulmonary" means "of the lungs"). It is illustrated in Figure below . Deoxygenated blood leaves the right ventricle through pulmonary arteries, which transport it to the lungs. In the lungs, the blood gives up carbon dioxide and picks up oxygen. The oxygenated blood then returns to the left atrium of the heart through pulmonary veins. Q: What gas do the lungs give up as they take in oxygen? Choices: - carbon monoxide - methane - nitrogen - carbon dioxide A:
A: carbon dioxide
Question: Answer the following question given this paragraph: Discussions of colors can sometimes become confusing because of the difference between light emitters and light absorbers. Light absorbers, such as dyes and pigments, absorb frequencies from those that you see, while light emitters add frequencies to what you see. If I were to shine red light, green light, and blue light into your eye all at the same time, you would likely see some variation of white. If I were to mix red paint, green paint, and blue paint together, you would likely see black or some very dark color. Q: What do light emitters do to what you see? Choices: - divide frequencies - subtract frequencies - block frequencies - add frequencies A:
Answer: add frequencies

Answer the following question given this paragraph: When current flows in just one direction, it is called direct current (DC) . The diagram below shows how direct current flows through a simple circuit. An example of direct current is the current that flows through a battery-powered flashlight. In addition to batteries, solar cells and fuel cells can also provide direct current. Q: What kind of current flows in just one direction? Choices: - physical current - slow current - Alternating current - direct current A:
**Answer**
direct current

Answer the following question given this paragraph: A hydration reaction is the opposite of a dehydration reaction. A hydration reaction adds water to an organic molecule and breaks the large molecule into smaller molecules. Hydration reactions occur in an acidic water solution. An example of hydration reaction is the breaking of peptide bonds in polypeptides. A hydroxide ion (OH - ) and a hydrogen ion (H + ) (both from a water molecule) bond to the carbon atoms that formed the peptide bond. This breaks the peptide bond and results in two amino acids. Q: What kind of reaction adds water to an organic molecule and breaks the large molecule into smaller molecules? Choices: - heat reaction - supplementation reaction - aerobic reaction - hydration reaction A:
**Answer**
hydration reaction
