Answer the following question given this paragraph: The continental slope lies between the continental shelf and the abyssal plain. It has a steep slope with a sharp drop to the deep ocean floor. Q: What lies between the continental shelf and the abyssal plain? Choices: - successive slope - continental belt - equator - continental slope A:
continental slope
Answer the following question given this paragraph: Saprotrophs are the final step in decomposition. They feed on any remaining organic matter that is left after other decomposers do their work. Saprotrophs include fungi and single-celled protozoa. Fungi are the only organisms that can decompose wood. Q: What are the only organisms that can decompose wood? Choices: - bacteria - protists - fossil - fungi A:
fungi
Q: Answer the following question given this paragraph: Like flowing water, wind picks up and transports particles. Wind carries particles of different sizes in the same ways that water carries them ( Figure below ). Q: How is flowing water and blowing wind similar? Choices: - processes particles - stocks particles - phases particles - transports particles A:
A: transports particles
Question: Answer the following question given this paragraph: Gluons ( g ) are the proposed carrier particles for the strong nuclear force, although they are not directly observed. Like quarks, gluons may be confined to systems having a total color of white. Less is known about gluons than the fact that they are the carriers of the weak and certainly of the electromagnetic force. QCD theory calls for eight gluons, all massless and all spin 1. Six of the gluons carry a color and an anticolor, while two do not carry color, as illustrated in Figure 33.22(a). There is indirect evidence of the existence of gluons in nucleons. When high-energy electrons are scattered from nucleons and evidence of quarks is seen, the momenta of the quarks are smaller than they would be if there were no gluons. That means that the gluons carrying force between quarks also carry some momentum, inferred by the already indirect quark momentum measurements. At any rate, the gluons carry color charge and can change the colors of quarks when exchanged, as seen in Figure 33.22(b). In the figure, a red down quark interacts with a green strange quark by sending it a gluon. That gluon carries red away from the down. Q: Like quarks, gluons may be confined to systems having a total color of what? Choices: - yellow - blue - red - white A:
Answer: white

Answer the following question given this paragraph: matrix and deposit calcium, which hardens the matrix. The non-mineralized portion of the bone or osteoid continues to form around blood vessels, forming spongy bone. Connective tissue in the matrix differentiates into red bone marrow in the fetus. The spongy bone is remodeled into a thin layer of compact bone on the surface of the spongy bone. Endochondral Ossification Endochondral ossification is the process of bone development from hyaline cartilage. All of the bones of the body, except for the flat bones of the skull, mandible, and clavicles, are formed through endochondral ossification. In long bones, chondrocytes form a template of the hyaline cartilage diaphysis. Responding to complex developmental signals, the matrix begins to calcify. This calcification prevents diffusion of nutrients into the matrix, resulting in chondrocytes dying and the opening up of cavities in the diaphysis cartilage. Blood vessels invade the cavities, and osteoblasts and osteoclasts modify the calcified cartilage matrix into spongy bone. Osteoclasts then break down some of the spongy bone to create a marrow, or medullary, cavity in the center of the diaphysis. Dense, irregular connective tissue forms a sheath (periosteum) around the bones. The periosteum assists in attaching the bone to surrounding tissues, tendons, and ligaments. The bone continues to grow and elongate as the cartilage cells at the epiphyses divide. In the last stage of prenatal bone development, the centers of the epiphyses begin to calcify. Secondary ossification centers form in the epiphyses as blood vessels and osteoblasts enter these areas and convert hyaline cartilage into spongy bone. Until adolescence, hyaline cartilage persists at the epiphyseal plate (growth plate), which is the region between the diaphysis and epiphysis that is responsible for the lengthwise growth of long bones (Figure 38.21). Q: This calcification prevents diffusion of nutrients into the matrix, resulting in what dying and the opening up of cavities in the diaphysis cartilage? Choices: - nanoparticles - phytocytes - keratinocytes - chondrocytes A:
**Answer**
chondrocytes
Q: Answer the following question given this paragraph: Hot spots are found within continents, but not as commonly as within oceans. The Yellowstone hot spot is a famous example of a continental hot spot. Q: The yellowstone hot spot is a famous example of a what? Choices: - form hot spot - oceanic hot spot - deeper hot spot - continental hot spot A:
A: continental hot spot
