Answer:
The finches on Galapagos Islands had different beak
The beaks of the finches changed over time
The Galapagos finches had a common ancestor
Explanation: Darwin's Finches are a good example of natural selection and adaptive radiation of evolution. The different finches in Galapagos Island have emerged from a common black, seed eating, short beak finches. This is called adaptive radiation, where different species arose from a single ancestor.
Due to changes in the natural environment, food resources, some finches have a long beak. This long beaks help them to eat insects. As a result, the competition will be less and nature selects them to survive in the new environment. This is a natural selection of evolution.

The kinds of rocks that weather most rapidly are sedimentary rocks due to the composition of the rock and several layers involved.
The process is decomposition.
Decomposition is a process by which organic substances, like leaves, are broken down into simpler matter. A lot of different types of organisms, called the decomposers, will consume the organic substances(like dead plants, dead animals) and continue an essential part of the nutrient cycle. This is important for recycling the organic matter that occupies space in the biosphere.
After the orginal trand has been seperated in DNA replication, the tRNA's bring together an amino acid, strands wind tightly together -corresponding base pairs are laid, and lastly, the bases are proofread for any errors.
