How are finches in the Galapagos islands a good example of adaptation?

solmaris [256]

The finches on the Galapagos Islands are a good example of adaptation because they all trace their ancestry into a small group of finches that inhabited these islands, but diversified in accordance to the environment. On the Galapagos Islands, there are finches that have numerous types of different beak shapes and sizes, despite them all being derived from a single group of finches that had the same characteristics. The reason for this is that once they got to these islands, there were multiple niches int the food chain that were free for taking. Some finches started to feed on plants, some on seeds, some became insect-eaters etc. Every food type needs special adaptation so that the finches can eat it more easily, or even be able to get to its nutritional part, thus their beaks started to change in accordance to their food preference.

Why is replication on one strand of dna continuous, while on the other strand the replication must be discontinuous?

Basile [38]

This is because DNA polymerase can only add new nucleotides in the 5’ to 3’ direction. In the replication bubble, the continuous strand is 5’-3’, however the discontinuous strand is 3’-5’. This forces DNA polymerase to use small primers and work backwards on the discontinuous strands, forming Okazaki fragments.

Use the list of words and place them under the correct category (DNA, RNA, or Both)

fiasKO [112]

Answer:

DNA: Deoxyribonucleic Acid, Double Helix, Double Stranded, Deoxyribose Sugar, Thymine, Instructions for making proteins, Located in Nucleus of Eukaryotes, Genetic Information,

RNA: Uracil, Copy the Instructions and Make Proteins, Cytoplasm, Ribosomes, Single Strand, Ribonucleic Acid, Ribose Sugar

Both: Nucleic Acid, 3 Types, Nucleotide is the monomer, 5-Carbon Sugar, Phosphate Group, Pyrimidines, Adenine, Guanine, Cytosine,

Explanation:

DNA or deoxyribonucleic acid, and RNA ribonucleic acid are made up of nucleotides, molecules that are essential to life- DNA stores genetic information, while RNA is important for facilitating the translation of DNA's information to proteins.

Nucleotides are monomers composed of DNA, a nucleic acid that serves as a storage molecule to encode proteins, along with RNA, a ribose sugar-containing nucleotide. In nucleotides, 5-carbon deoxyribose or ribose sugar, phosphate and one of four bases of nitrogen are found:

Adenine (A)

Guanine (G)

Cytosine (C)

Thymine (T).

Uracil (U) found in RNA
