16 B: muscle tone is Constant tension by muscles for long periods of time
17 D: stratum basale basal layer sometimes referred to as stratum germinativum
18 E: simple columnar epithelium
19 C: by interfering with the synthesis of prostaglandins, aspirin prevents platelet plug formation
20 C: fibrinolysis is responsible for breaking down of the fibrin clot known as clot dissolution
