Explain to someone who knows nothing about fossils the study of invertebrate paleontology and how it helps scientists understand the history of the earth. Be sure your explanation contains a minimum of two complete sentences.

Paleontology is the study of the history of life on Earth as based on fossils. Fossils are the remains of plants, animals, fungi, bacteria, and single-celled living things that have passed away and replaced by some rock material. They're impressions of organisms preserved in rock. Paleontologists use fossil remains to understand different aspects of extinct and living organisms.

Vertebrate paleontology and invertebrate are subfields of paleontology. It is the scientific study of ancient invertebrates. They do this by analyzing invertebrate fossils.

All of this, all this studying helps to know our past. Perhaps our descendants. It helps to know how the animals at whatever period were capable of, how they lived, if they were living good or struggling, perhaps possible death situations that may happen to us and prevention, etc...

Explanation:

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
