To conduct a phylogenetic analysis, we need an outgroup to:

A. decide which characters are analogous and which are homologous.

B. determine which character states are ancestral and which are derived.

C. determine which characteristics to include in our analysis.

D. decide which molecular data to use.

E. All of the answer options are correct.

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.
