<span>In an event of a rattlesnake bite, keeping the person bitten to calm down is the 1st thing to do. When the venom reaches the heart of the victim, it could lead to a fatal death. So by calming down, the circulation of blood is prevented to rise. After which, they directly cut an "x" at the middle of the bite marks and suck out blood as many as possible hoping that the venom is also sucked out too. This was an old technique used in the Oregon trail and may not be the best technique there is nowadays.

High levels of circulating glucocorticoids (GC) activate the HPA (hypothalamic-pituitary-adrenal).
The hypothalamic-pituitary-adrenal (HPA) axis, an intricate yet robust neuroendocrine mechanism that mediates the effects of stressors by regulating numerous physiological processes such as metabolism, immune responses, and the autonomic nervous system, is a key component of the homeostatic response (ANS). The hypothalamus, anterior and posterior pituitary glands, and adrenal cortex are the three primary components of the HPA axis.
The hypothalamic-pituitary-adrenal (HPA) axis, which regulates stress hormones such as glucocorticoids and, in particular, cortisol, may be involved in this process.
Corticosteroids, which are steroid hormones, are a subclass of glucocorticoids. Glucocorticoids are corticosteroids that bind to the glucocorticoid receptor, which is found in nearly every cell of a vertebrate animal.

Answer:
The best answer to the question: The focus of this study is MOST accurately defined as:___, would be: Insomnia.
Explanation:
This scientist wishes to investigate the effects of failure of sleep on athletic performance. However, the characteristics of the people he is seeking to form part of his research sample group are very unique in that all of them have had loss of sleep, be it complete, or partial, but it does not matter the reasons as to why these people were unable to sleep. So, most likely what this researcher is looking for is simply to define the effects of insomnia, which is simply defined as the inability of a person to get enough sleep, regardless of causation.
