Answer:
<h2><em><u>C. Incident.</u></em></h2>
Explanation:
Incidents surprise people, causing then to jump. This happened even when the incident did not actually cause any pain for the person. Hope this helps!
Answer:
Both Howard and Harold are at the risk of developing Alzheimer disease. But Harold has much greater risk because of his lifestyle.
Explanation:
The major risk of developing the Alzheimer disease is age. The likelihood of developing this disease will increase twice as much every 5 years beginning at age 65. Thus , the fact that Howard and Harold are 66 increases both their chances of developing this disease. Furthermore, the disease is also associated with other life threatening conditions such as high blood pressure and diabetes. However, a balanced nutritious diet, physical activities, and mentally stimulating games might help reduce the chances of getting the disease. Respectively, Harold's lifestyle increases the chances of developing the Alzheimer disease to a greater extent as compared to Howard's lifestyle.
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.
