Which of the following is not a vertebrate developmental stage? beginning stage growth stage pupa stage adult stage

Pupa stage

Vertebrates are the organisms that exhibit a vertebral column and they have bilateral body composition in which one side of the body is the mirror image of the other around their backbones. They typically exhibit three stages in their development cycle: egg, juvenile and adult. Pupa is the developmental stage found in the invertebrates.

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.
