<span>They are composed of similar materials: DNA is a deoxyribonucleotide polymer while RNA is a ribonucleotide polymer. A nucleotide is composed of a nitrogenous base, a sugar, and a phosphate group. In ribonucleotides, the sugar is ribose, while in deoxynucleotides, the sugar is deoxyribose. Adenine, guanine, and cytosine are nitrogenous bases in both DNA and RNA, while thymine is found only in DNA and uracil is found only in RNA.</span>

Stimulation of glucose production and release into circulation to provide a quick fuel source for muscle tissue so that the body is readied for action during a stress event.
Option B.
<h3><u>Explanation:</u></h3>
Cortisol is a steroid group of hormone that is secreted from the Adrenal Cortex from the zona fasciculata. It's the middle layer of Adrenal Cortex. Cortisol helps in different functions of the body that includes the suppression of immune system, increasing the blood sugar level, gluconeogenesis, metabolism of fat, and proteins. This hormone helps in the gluconeogenesis which helps to produce glucose from non glucose sources. The primary sources include the fats and proteins and the glycogen reserve in liver and muscles. Thus increase in cortisol levels help in the retaining glucose levels in stress or hypoglycemia.
