The part of cellular respiration in which glucose is broken down is called

Glycolysis

Explanation:

In cellular respiration Glycolysis is an anaerobic process in which one molecule of glucose is broken down into two molecules of pyruvate and two net ATP and 2 NADH are produced.

For complete oxidation of glucose in an aerobic condition pyruvate is converted to a two carbon acetyl CoA which enters the TCA or Krebs Cycle.

In the TCA cycle during cellular respiration acetyl CoA is completely oxidized to a carbon molecule CO2, and produces energy rich molecules that are used in the electron transport chain.

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.
