How did these prints become trace fossils?
Trace fossils are things like foot prints, burrows, and fossilized feces (coprolites). So quite simply, they're formed by the living-part of an animal's life (rather than its death, being buried as a body fossil). If there's a muddy bottom and an animal crawls across it, it could leave an imprint. Burrows could left behind. These divots and so on can get filled in with hardy sediment that becomes fossilized when the mud is covered over and the sediments become a standard sedimentary rock containing trace fossils.
When is a carbocation formed?
A carbocation is formed when a alkane or a alkyl group containing molecule undergoes through a SN1 reaction.
What does the blastopore become?
At the stage of development when the gut forms there is only a single opening into the digestive track, this opening may become either the mouth or anus.
