Q: Answer the following question given this paragraph: Magma composition determines both eruption type and volcano type. Q: What composition determines both eruption type and volcano type? A:

OPTIONS:
- electrical
- chemical
- gas
- magma

A: magma

input: OPTIONS:
- filaments
- antibodies
- carbon
- phospholipids Now, answer this question: Answer the following question given this paragraph: The plasma membrane is composed mainly of phospholipids, which consist of fatty acids and alcohol. The phospholipids in the plasma membrane are arranged in two layers, called a phospholipid bilayer . As shown in Figure below , each phospholipid molecule has a head and two tails. The head "loves" water (hydrophilic) and the tails "hate" water (hydrophobic). The water-hating tails are on the interior of the membrane, whereas the water-loving heads point outwards, toward either the cytoplasm or the fluid that surrounds the cell. Q: What is the plasma membrane mainly composed of? A:
A:
output: phospholipids

Answer the following question given this paragraph: hydrophilic heads are directed outward, in contact with the water. Each micelle may contain thousands of lipid molecules. Polar lipids may also form a monolayer, a layer one molecule thick on the surface of the water. The polar heads face into water, and the nonpolar tails stick up into the air. Bilayers are double layers of lipids arranged so that the hydrophobic tails are sandwiched between an inner surface and an outer surface consisting of hydrophilic heads. The hydrophilic heads are in contact with water on either side of the bilayer, whereas the tails, sequestered inside the bilayer, are prevented from having contact with the water. Bilayers like this make up every cell membrane (Figure 17.6 "Schematic Diagram of a Cell Membrane"). Figure 17.5 Spontaneously Formed Polar Lipid Structures in Water: Monolayer, Micelle, and Bilayer. Q: When something is described as "hydrophilic", you can determine something about how it interacts with what? A:

OPTIONS:
- hydrogen
- air
- iron
- water

Answer: water

Problem: OPTIONS:
- expand
- generate
- melt
- evaporate
Q: Answer the following question given this paragraph: Always properly dispose of hazardous waste. For example, let liquid waste evaporate before placing the container in the trash. Q: What should you let liquid waste do before placing the container in the trash? A:
Answer: evaporate

Problem:OPTIONS:
- removal
- irrigation
- urban renewal
- reclamation

Answer the following question given this paragraph: U. S. law states that once mining is complete, the land must be restored to its natural state. This process is called reclamation . A pit may be refilled with dirt. It may be filled with water to create a lake. The pits may be turned into landfills. Underground mines may be sealed off or left open as homes for bats. The land is reshaped. Native plants are planted. Q: When land used for mining or other purposes is restored to its natural state, what do you call the process, which is often mandated by law? A:
****
A: reclamation

Problem:OPTIONS:
- spleen
- skin
- colon
- liver

Answer the following question given this paragraph: Urea Cycle The urea cycle is a set of biochemical reactions that produces urea from ammonium ions in order to prevent a toxic level of ammonium in the body. It occurs primarily in the liver and, to a lesser extent, in the kidney. Prior to the urea cycle, ammonium ions are produced from the breakdown of amino acids. In these reactions, an amine group, or ammonium ion, from the amino acid is exchanged with a keto group on another molecule. This transamination event creates a molecule that is necessary for the Krebs cycle and an ammonium ion that enters into the urea cycle to be eliminated. In the urea cycle, ammonium is combined with CO2, resulting in urea and water. The urea is eliminated through the kidneys in the urine (Figure 24.18). Q: The urea cycle, a set of biochemical reactions that produces urea from ammonium ions to prevent toxicity, occurs to some extent in the kidney, but primarily in what organ? A:
****
A:
liver
