The Glycogenin has a tyrosine amino acid group , which have a hydroxyl group , on which the glucose unit is attached .  

The first molecules of Glucose to Glycogenin is transfered by the nezyme Glycogen initiator synthase .

Ahat [919]

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.

Anettt [7]
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.
