6 Answer Key Testname: CHAPTER3 1) C 2) B 3) E 4) E 5) B 6) A 7) E 8) D 9) E 10) B 11) A 12) E 13) D 14) D 15) A 16) C 17) A 18) E 19) D 20) B 21) A 22) nuclear pores 23) C 24) differentiation 25) Cancer results when cells begin to divide and grow and do not respond to normal controls that would limit their growth. Anchoring junctions eventually fail to keep the cancer cells together, allowing them to spread to other organs where they continue to grow uncontrolled. Some cancer cells secrete proteases that improve their ability to spread or metastasize. A tumor is a lump of cancerous cells. Cancer is usually not contagious, being caused instead by genetic mutations in an individual or exposure to environmental factors by that individual; exceptions are cancers caused by viruses, which are believed to be the minority. 26) glands 27) histology 28) Peripheral 29) D 30) This is discussed in the "Tissues of the Body" section of the chapter. 31) This is discussed in the "Tissue Remodeling" section of the chapter. 32) All are structures involved in synthesis of biomolecules. All but ribosomes are membranous structures. Ribosomes may be free or attached to ER, making it rough. See Fig in the chapter. 33) The cytoskeleton consists of actin microfilaments, intermediate filaments, and microtubules and forms a scaffolding throughout the cytoplasm. An interesting feature is that some of the proteins are relatively fixed in position, whereas others can be rapidly assembled or disassembled as necessary. The functions include providing mechanical strength and shape, stabilizing position of organelles, intracellular transport system, functional linkage to other cells and to extracellular space, and cell-generated movements. 34) In any tissue, the extracellular matrix consists of two basic components proteoglycans and insoluble proteins. The matrix plays an important role in processes ranging from growth and development to cell death. The matrix aids in cell communication with its environment by attaching to the cell membrane or cytoskeleton. 6 35) Since gases must diffuse across the alveoli and associated capillaries you would expect to find exchange epithelia, composed of very thin cells (simple squamous epithelium). Thicker types of epithelial cells would slow the process of gas diffusion to and from the blood.
