What is a fossil and how do they form? Explain.
Fossils are preserved remains of an organisms or traces of living remains. Sediment surrounding the organism turns into stone and the original remains dissolved leaving a mold.

how do fossils form
a mold creates a hollow area inside a rock that is shaped of an organism or part of an organism
what are protiens

A mutation
True or false- The process by which two species evolve in response to changes in each other over time is called natural selection.
False- It is called Coevolution.
