Loss of islet beta cells is the pathologic abnormality most likely to be present in her pancreas at the time of her collapse.
<h3>What are islet beta cells?</h3>
The islets of Langerhans, which are cellular islands dispersed throughout the endocrine pancreas in most animals, include four main kinds of cells, the -cell being one of them. The beta-cell primarily produces and secretes the hormone insulin in reaction to glucose, while it can also do so in response to other foods, hormones, and nervous system stimulation. Adult rats have a sluggish mitotic rate in their -cells. Recent research offers fresh perspectives on the -cell's functioning. An major role for insulin/IGF-1 signaling in the control of -cell activity is suggested by the existence of functioning insulin, insulin receptors, and IGF-1 signaling pathway components. Glucokinase (GK) and ATP-dependent potassium channels have also recently been found on insulin secretory granules.

Answer:
make an exact copy of a DNA strand for bacterial reproduction
Explanation:
The purpose of DNA replication would be <u>to make an exact copy of a DNA strand for bacterial reproduction.</u>
<em>DNA replication is a process during which an extra copy of an organism's DNA is made following a series of steps. The replication usually precedes reproduction or the formation of daughter cells. Each daughter cells resulting from reproduction must have a complete genome that mirrors that of the parent or otherwise depending on the type of reproduction. </em>
Without reproduction, DNA replication would not have been necessary.
When a skeletal muscle fiber is at rest, its ATP demands are met by ADP and creatine phosphate. In a resting muscle, excess ATP transfers its energy to creatine, producing ADP and creatine phosphate. This acts an energy reserve that can be used to quickly create more ATP. When the muscle starts to contract and needs energy, creatine phosphate transfers its phosphate back to ADP to form ATP and creatine.
