Explanation:
Galapagos islands are groups of island in the pacific ocean that are known to have a wide range of native animals such as giant tortoise that found no where else on earth. These native animals helped Darwin in the development of the theory of natural significance which attributes to the biological significance of the Galapagos islands. Human species is a threat to the natural wildlife on these islands mainly due to poaching and destruction of natural forests that destroys habitat and also impacts negatively on biological diversity of living organisms.
<u><em>The nitrogenous base</em></u> is the central information carrying part of the nucleotide structure. These molecules, which have different exposed functional groups, have differing abilities to interact with each other.
<u><em>The second portion of the nucleotide is the sugar.</em></u> Regardless of the nucleotide, the sugar is always the same. The difference is between DNA and RNA. In DNA, the 5-carbon sugar is deoxyribose, while in RNA, the 5-carbon sugar is ribose. This gives genetic molecules their names; the full name of DNA is deoxyribonucleic acid, and RNA is ribonucleic acid.
<u><em>The last part of nucleotide structure, the phosphate group</em></u>, is probably familiar from another important molecule ATP. Adenosine triphosphate, or ATP, is the energy molecule that most life on Earth relies upon to store and transfer energy between reactions. ATP contains three phosphate groups, which can store a lot of energy in their bonds. Unlike ATP, the bonds formed within a nucleotide are known as phosphodiester bonds, because they happen between the phosphate group and the sugar molecule.
<h2>
Answer:</h2>
The correct answer is option D which is that endocrine control can control melatonin.
<h2>
Explanation:</h2>
As melatonin is released from pineal gland which is a part of endocrine system.The endocrine system is a chemical messenger system which has glands, which secretes certain chemicals known as hormones.These hormone acts on different organs to control different metabolisms in body.So melatonin which is hormone can be controlled by the endocrine system.
