Answer the following question given this paragraph: 38.2 Bone Bone, or osseous tissue, is connective tissue that includes specialized cells, mineral salts, and collagen fibers. The human skeleton can be divided into long bones, short bones, flat bones, and irregular bones. Compact bone tissue is composed of osteons and forms the external layer of all bones. Spongy bone tissue is composed of trabeculae and forms the inner part of all bones. Four types of cells compose bony tissue: osteocytes, osteoclasts, osteoprogenitor cells, and osteoblasts. Ossification is the process of bone formation by osteoblasts. Intramembranous ossification is the process of bone development from fibrous membranes. Endochondral ossification is the process of bone development from hyaline cartilage. Long bones lengthen as chondrocytes divide and secrete hyaline cartilage. Osteoblasts replace cartilage with bone. Appositional growth is the increase in the diameter of bones by the addition of bone tissue at the surface of bones. Bone remodeling involves the processes of bone deposition by osteoblasts and bone resorption by osteoclasts. Bone repair occurs in four stages and can take several months. Q: Osseous tissue - the connective tissue that includes specialized cells, mineral salts, and collagen fibers - makes up what? Choices: - muscles - spine - ligaments - bone A:
bone

Answer the following question given this paragraph: The pointed pattern is a form of partial albinism, which results from a mutation in an enzyme that is involved in melanin production. The mutated enzyme is heat-sensitive; it fails to work at normal body temperatures. However, it is active in cooler areas of the skin. This results in dark coloration in the coolest parts of the cat's body, such as the lower limbs and the face, as shown in Figure above . The cat's face is cooled by the passage of air through the nose. Generally adult Siamese cats living in warm climates have lighter coats than those in cooler climates. Q: Partial albinism results from a mutation in an enzyme that is involved in the production of what? Choices: - cytoplasm - hair - cancer - melanin A:
(A).
melanin

Choices: - testosterone - insulin - glucose - estrogen A:

Answer the following question given this paragraph: Feldspar and quartz are the two most common silicates. In beryl, the silicate pyramids join together as rings. Biotite is mica. The silicate pyramids come together to create thin, flexible sheets. Compare the beryl and the biotite pictured below ( Figure below ). Q: What are the two most common silicates? Choices: - Analcime and Feldspar - Petalite and Quartz - Petalite and Analcime - feldspar and quartz A:
