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.
Red blood cells carry oxygen around the body. These specialized cells are outfitted with the substance hemoglobin, which is a protein, and is the actual oxygen carrying molecule on the cell. The cell has a unique shape that allows it to carry as much oxygen molecules as possible. Red blood cells also transport carbon dioxide away from cells and back to the lungs where the cells are then re-oxygenated.
D.
Since results and genetic engineering haven’t been fully tested and operational, the results are currently unpredictable.
Hope this helps!
