The correct answer is HPA axis.
The Hypothalamic-Pituitary-Adrenal (HPA) axis is one of the most important neuroendocrine systems, which regulates the stress response and other functions such as the digestion, mood, emotions and the immune system.
The hypothalamus, when triggered by a possible stressor, releases two hormones; the vasopressin and the corticotropin-releasing hormone (CRH). CRH, in turn, triggers the release of the adrenocorticotropin hormone (ACTH) from the pituitary gland. As a result of the secretion of ACTH, cortisol is secreted by the adrenal cortex.
Cortisol is a steroid hormone, considered to be our body's stress hormone.
Scientists use fossils to study earth history by identifying the fossil and what era it came from. By knowing what era the fossil came from and what location it was found, scientists can make assumptions about the earth formation at that time.
The answer relates to the medium in which the sensed molecules travel. On land, animals detect a scent through organic molecules transported in the air. Land animals will experience a taste sensation by grasping an object using their mouth. Here, the organic molecules providing the sensation are transported by saliva or organic fluids of the object. So on land, there is a clear distinction between molecules transported in the wind and those that can be tasted. Water is a much more dense medium than air, and can carry small and large organic molecules, unlike air. Therefore, aquatic animals have little need for olfactory organs as all molecules can be 'tasted' from the water.
These nucleotides have three parts: 1) a five carbon ribose sugar, 2) a phosphate molecule and 3) one of four nitrogenous bases: adenine, guanine, cytosine or uracil.
The lifelong process of learning and internalizing the norms of society, in which we interact is called socialization.
The role of socialization is for a person to learn, through interaction with others, the norms of a given society. It prepares individuals to participate in a community by exposing the individual to the rights and wrongs of each community. Socialization is most important for children and should begin during the home phase.
Socialization is a lifelong process. Over time and throughout the course of our lives, we interact with others in our communities. Which each and every interaction we can learn more about what is acceptable In society and for each of our peers
