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.

The skeleton of your larynx is composed of nine cartilages that are joined together and supported by a series of ligaments, muscles and membranes. Three of these cartilages (the cricoid cartilage, the thyroid cartilage, and the epiglottis) are single, and three (the cuneiforms, corniculates, and arytenoids) are paired.he opening between the vocal cords is called the rima glottidis, or simply the glottis. The arytenoid cartilages, which anchor the vocal cords at the rear of your larynx, play a major role in tightening and moving your vocal cords in and out to vary the pitch of the sounds you make.
