One example of scientist taking different approaches that lead to the same result is

The given question is incomplete, the complete question is:

One example of scientists taking different approaches that lead to the same result is

A). two scientists testing different hypotheses about the same observation.

B). two scientists repeating a third scientist’s experiment as published.

C). two scientists working on one experiment at the same time in different labs.

D). two scientists performing one experiment at different times in the same lab.

The correct answer is statement A, that is, two scientists testing different hypotheses about the same observation.

Explanation:

The correct answer is statement A, as examining different hypotheses regarding the same observation may give a similar result. A proposed explanation or supposition made based on the confined proof as an initiation point for further investigation is known as a hypothesis.  

In statement B, the scientists are not considering distinct approaches, however, they are both performing an experiment published earlier. In statement C, scientists have considered a similar approach and are separated spatially. In statement D, the scientists are also considering a similar approach, however, are distinguished temporally.  

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.
