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:
Student's t-test
Explanation:
The student's t-test is used to compare, measure or evaluate two independent groups. It helps to show the significant differences between two groups that are significantly different from each other, in this case, the two immersive learning treatments. It helps to measure if the differences which is usually measured in mean, happened by chance.
It is the most appropriate method for comparing two groups with a continuous variable. Forms of Student's t-test are the paired t-test, unpaired t-test, single sample, etc.
Answer:
The neonatal period is the first 28 days of life. It is the period when new born babies are vulnerable to health problems. Considering health problem analysis framework, Infant or neonatal mortality is rampant at this stage of life, as babies(one month or below) have low chances of surviving. Better care or better babies care focus intensive care for neonates, and reducing their mortality rate.
Public health science outcome-orientated perinatal surveillance system can be explained as an objective, understandable, and acceptable basis for establishing monitoring evaluation, and regulatory strategies for hospitals with units for maternity and newborns. It is also the continuous, systematic collection, analysis and interpretation and data related to newborn babies in Hospitals, for the planning, implementation, and evaluation of public health practice.
Explanation:
Health problems are situations or conditions of people which are considered undesirable. It is measured as death, disease and disability.
