Aseries of experiments, which are repeated over and over, seem to suggest that a scientific theory is incorrect. what does this most likely mean?

a. the experiments were faulty.
b. the scientist was manipulating the results.
c. the theory must be revised.
d. the results should be modified to agree with the theory.

The correct answer is option C. The theory must be revised.

The theory is the scientific explanation of a phenomenon, which explains the working and its causes. The experiments performed to give a theory must be replicatable and must produce the same result all the time. In case, the experiment according to the theory produces different result many times when performed by different scientists, then there must be some fault in the theory, then it need to be revised.

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.

this is math not biology xd
