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.

Answer:
Kyla could not recall where she had been or what she had done all day.
Explanation:
Dissociative identity disorder may be defined as a psychological disorder and is mainly caused by repetitive, physical or sexual abuse. This is also known as multiple personality disorder.
The individual lacks the connection of the feeling, memories, emotion and sense of identity. The individual may become violent, excess traumatic and unable to control himself. Kyla case shows the dissociative identity disorder as she is unable to recall her whole day activity.
Thus, the correct answer is option (d).
Hepatitis<span> A </span>virus<span> is usually spread from person to person by putting something in the mouth that has been contaminated with the stool of a person with </span>hepatitis<span> A. This type of transmission is called the "fecal-oral" route.</span>
125 ml/hour x X hours = 1000 ml
X = 1000 ml/ 125 ml/hour
X = 8
It will take 8 hours
