Will mark Branliest if correct. (I think B, but I am not sure. It doesn't seem to be D.) What makes mitochondrial DNA useful as a molecular clock? (2 points)

It is only found in select organisms, making it easier to compare relationships between species that have it.

A large portion of the DNA ring is not vital to structure or function, allowing it to accumulate neutral mutations.

Its rate of mutation increases over time as organisms continue to evolve and differentiate from each other.

A slow mutation rate makes it useful for determining evolutionary relationships between ancient species.

Mitochondrial DNA is useful as a molecular clock because it displays uniparental inheritance

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.
