Answer:
Chemically altered nucleosides derived from canonical ribo-or deoxyribonucleoside-derivatives of adenosine, cytosine, guanosine, and uridine or thymidine are found in all types of nucleic acids, DNA and RNA. They are particularly abundant in noncoding RNAs, such as transfer RNAs and ribosomal RNA of higher organisms. By increasing the structural diversity of nucleic acids, modified nucleosides play important roles in gene expression and in regulating many aspects of RNA functions. They also contribute to nucleic acid stability and to protection of genetic materials against virus aggression. In this chapter we present a historical overview of the discovery, occurrence, and diversity of the many naturally occurring modified nucleosides that are present in both DNA and RNA of diverse organisms. We also briefly describe the different enzymes that accomplish these nucleic acid ‘decorations’. More information about the structure, function, biosynthesis and evolutionary aspects of selected modified nucleosides in DNA and RNA and their corresponding modification enzymes can be found elsewhere in this volume.

By components do you mean organs? If so...
1. Brain - gives demands ands orders to all of the body to function properly
2. Heart - pumps blood, and keeps the organism receiving the blood alive
3. Skin - protects the tissue from UV Rays that may be harmful
Answer:
Tell her to wait until October to discuss plan choices with you so that you can share plan benefits for the current year as well as any changes for the following year that may impact her choice
Explanation:
Fat is a quite simple component to measure. Increased or
above normal/ average body fat has been proven to be linked with many health
risks.<span>
<span>Body weight is not always an accurate indication
of body composition. If you were to equate an NFL running back who is 5'
10" and weighs 200 lbs, to a 5'10" 200 lbs. banker, there body
composition would be VERY unalike although there weight is exactly the same. Of
course the football player is healthier, because he is perhaps carrying one
third of the body fat as the banker of the same weight. Maintaining that muscle
mass would also infer healthy habits like nutrition and exercise.</span></span>
