The prevalence of a disease is 12% in population X (n = 10,000). Two screening tests have been developed for this disease. Individuals first undergo screening test 1, which has a sensitivity of 85% and specificity of 80%. Only individuals who test positive from screening test 1 undergo the more invasive screening test 2, which has a sensitivity of 90% and a specificity of 80%. Please complete the following contingency tables: Screening Test 1

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.
