<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.
Answer:
A. Yes. All phylum members are classified together in the same kingdom
Explanation:
This because there are two broad classification of living organisms which are plants kingdom and animal kingdom which have several subdivisions under each. The phylum molluscs is under the animal kingdom because all the organism present under it are animals. The group consist of majorly eukaryotic, multicellular organisms that are heterotrophic in nature.
Answer:
True
Explanation:
The sympathetic autonomic nervous system activates the body for hormonal or neuronal responses also known as fight- or - flight response, For example during an fire emergency and there is a need to run. The response occurs primarily by via impulses transmitted through the sympathetic nervous system, and also secondarily through catecholamines secreted from the adrenal medulla.
Although the sympathetic autonomic nervous system is activated in stressful conditions, it needs to be constantly active even at a basal level to maintain homeostasis.
Answer:
a. adenine and guanine
Explanation:
A purines nucleotide is a combination of the heterocyclic aromatic rings, the imidazole and pyrimidine ring.
1) Cholesterol is important for the production of hormones, for example, some hormones are synthesized (made) from cholesterol - for example stereoid hormones.
2) Vitamin D is also made from cholesterol- it's an important vitamin used to support the absorption of calcium
