Answer the following question given this paragraph: Excretion is the process of removing wastes from the body. Q: Name the process of removing wastes from the body. Choices: - filtration - depletion - degradation - excretion A:
excretion
Answer the following question given this paragraph: Many of the problems with fossil fuels are worse for coal than for oil or natural gas. Burning coal releases more carbon dioxide than either oil or natural gas. Yet coal is the most common fossil fuel, so we continue to burn large amounts of it. That makes coal the biggest contributor to global warming. Q: What is the most common fossil fuel? Choices: - diesel oil - uranium - methane - coal A:
coal
Q: Answer the following question given this paragraph: Ulna The ulna is the medial bone of the forearm. It runs parallel to the radius, which is the lateral bone of the forearm (Figure 8.6). The proximal end of the ulna resembles a crescent wrench with its large, C-shaped trochlear notch. This region articulates with the trochlea of the humerus as part of the elbow joint. The inferior margin of the trochlear notch is formed by a prominent lip of bone called the coronoid process of the ulna. Just below this on the anterior ulna is a roughened area called the ulnar tuberosity. To the lateral side and slightly inferior to the trochlear notch is a small, smooth area called the radial notch of the ulna. This area is the site of articulation between the proximal radius and the ulna, forming the proximal radioulnar joint. The posterior and superior portions of the proximal ulna make up the olecranon process, which forms the bony tip of the elbow. Q: What is the medial bone of the forearm that runs parallel to the radius? Choices: - humerus - fibula - radius - ulna A:
A: ulna
Question: Answer the following question given this paragraph: Soils may also remain in place but become degraded. Soil is contaminated if too much salt accumulates. Soil can also be contaminated by pollutants. Q: What natural resource can be damaged by the accumulation of too much salt? Choices: - forests - sediment - mineral - soil A:
Answer: soil

Answer the following question given this paragraph: As Melvin Calvin discovered, carbon fixation is the first step of a cycle. Like an electron transport chain, the Calvin Cycle, shown in Figure below , transfers energy in small, controlled steps. Each step pushes molecules uphill in terms of energy content. Recall that in the electron transfer chain, excited electrons lose energy to NADPH and ATP. In the Calvin Cycle, NADPH and ATP formed in the light reactions lose their stored chemical energy to build glucose. Q: Carbon fixation is the first step of what cycle involving light reactions? Choices: - sun cycle - life cycle - water cycle - calvin cycle A:
**Answer**
calvin cycle

(A).
spherical aberration
