Less freshwater! Good luck!
Vestigial structures are parts of an animal's body that serve no function, but did in earlier evolutionary stages. Two examples of this are the human appendix and the snake pelvic bone.
They can both be used to identify organisms. Also, the phenotype of an organism is different depending on the genotype of the organism, making them relate to one another.
Hope this helps. Good luck! :)
<span>1. D dripstone produced by buildup of minerals precipitated from groundwater.
Water drips down from, for example, the roof of a cave and slowly leaves behind mineral deposits which form a shape similar to an icicle
2. D running water cuts small channels into a slope
Rill erosion is formed by soil removal from small streams of running water. They form based on how the water falls down a slope and tend to migrate to already depressed or softer areas of soil.</span>
