A student argues that two species of birds are the same species because they have similar body structures, similar DNA, and similar beaks. Another student argues that the birds are different species because they have different color patterns and have a different mating season. Which piece of evidence supports the second student's argument?

"The birds have different mating seasons" piece of evidence supports the second student's argument.

Explanation:

The precise timing for bird sets to successfully match varies, and the timing for distinct species develops to give the consequent chicks the best chance of survival. Speciation is the mechanism through which new species are produced. This happens when classes within an individual are separated and diverge reproductively.

Organisms contribute to the same group as per the biological species definition if they can reproduce in order to create healthy, fertile offspring. Group are divided by prezygotic and postzygotic restrictions which prevent mating or producing viable, fertile offspring from each other.

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.
