Answer the following question given this paragraph: Exocrine Glands Exocrine glands release their contents through a duct that leads to the epithelial surface. Mucous, sweat, saliva, and breast milk are all examples of secretions from exocrine glands. They are all discharged through tubular ducts. Secretions into the lumen of the gastrointestinal tract, technically outside of the body, are of the exocrine category. Q: Through what part do exocrine glands discharge their contents? A:
OPTIONS:
- follicles
- capillaries
- urethra
- tubular ducts
tubular ducts

Answer the following question given this paragraph: 30.5 Applications of Atomic Excitations and De-Excitations 30. Figure 30.39 shows the energy-level diagram for neon. (a) Verify that the energy of the photon emitted when neon goes from its metastable state to the one immediately below is equal to 1.96 eV. (b) Show that the wavelength of this radiation is 633 nm. (c) What wavelength is emitted when the neon makes a direct transition to its ground state? 31. A helium-neon laser is pumped by electric discharge. What wavelength electromagnetic radiation would be needed to pump it? See Figure 30.39 for energy-level information. Ruby lasers have chromium atoms doped in an aluminum oxide crystal. The energy level diagram for chromium in a ruby is shown in Figure 30.64. What wavelength is emitted by a ruby laser?. Q: A desmosome is a cell structure that anchors the ends of what fibers together? A:
OPTIONS:
- skeletal muscle
- controllable muscle
- smooth muscle
- cardiac muscle
cardiac muscle

Answer the following question given this paragraph: Dissolved mineral salts wash into the ocean. As ocean water evaporates, it leaves the salts behind. This makes the water saltier. Ocean water is about 3.5 percent salts. The main salt is sodium chloride. Q: Concentration of what, the substance left behind when ocean water evaporates, is about 3.5 percent? A:
OPTIONS:
- hydrogen
- sugar
- quartz
- salts
