Finally, do not apply asphalt over a newly sealed surface. The surface should be grey, much like the street in front of your house. Although the binder coat may last by itself, a finer aggregate top coat will provide a surface that is more resistant to water infiltration and damage.
24. Gases in the alveoli must cross two layers of epithelium and a layer of fused basement membrane to reach the blood. True. False. 25. There are two folds of muscle and connective tissue in the larynx called the vocal cords or vocal folds; the inferior pair are the true vocal cords involved in speech.4.

Read an explanation of this examination online. The larynx houses the vocal cords, two elastic bands of tissue (right and left) that form the entryway into the trachea (airway). Above and to the sides of the true vocal cords are the false vocal cords, or ventricular cords.oice production begins with respiration (breathing). Air is inhaled as the diaphragm (the large, horizontal muscle below the lungs) lowers. The volume of the lungs expands and air rushes in to fill this space. We exhale as the muscles of the rib cage lower and the diaphragm raises, essentially squeezing the air out.
