I think the answer is<span> all species evolve from pre-existing species. This was based on Charles Darwin's Theory of Evolution which he learned during his expeditions.He identified that some fossils have similarities with other existing animals, in which he believed were a part of adaptation in order to survive.</span>
The answer is 'cooler'. The Cretaceous Period was relatively warm and was experiencing global warming. However, a cooling trend was evident towards the end of the Cretaceous. The Paleocene followed the meteorite impact that resulted in the extinction of most of the dinosaurs. It is thought that dust particles in the atmosphere resulted in cooling during the early Paleocene.
Answer: Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin. Several enzymes and proteins then work together to prepare, or prime, the strands for duplication. Finally, a special enzyme called DNA polymerase organizes the assembly of the new DNA strands. The following description of this three-stage process applies generally to all cells, but specific variations within the process may occur depending on organism and cell type.
