There is a major difference between homeostasis and allostasis. Sterling and Eyer (1988) coined the term allostasis to mean that
The primary explanatory framework for physiological control, homeostasis, has undergone major adjustment in recent years, with modern models varying greatly from the original formulation.
Allostasis, a different perspective on physiological control, extends beyond its homeostatic foundations, providing unique insights pertinent to our understanding and treatment of a variety of chronic health disorders. Despite increased interest in allostasis, the notion remains ambiguous, in part because of uncertainty in how the term is defined and used, hindering effective translational and clinical research on allostasis.

The prototype approach assumes that stimuli are classified into different concepts based on features that are set of entities within the category that represent a prototypical member.
The acquisition of a prototypical representation of a category through some sort of abstraction process, according to prototype theory, is how categorization is accomplished. According to Posner (1969) and Neumann (1977), the prototypical representation is thought to be a summary representation that represents the "central tendency" of all the examples that have been encountered. Then, new examples can be categorized according to how closely they resemble this "best example." Think about what happens when someone is asked to envision a category like "tree," for instance.

For each molecule of glucose that is processed by glycolysis and the citric acid cycle, what is the total number of nadh fadh2 molecules produced?
12 is the total number of NADH FADH2 molecules that will be produced.
In each citric acid cycle, one molecule of FADH2 is formed during the conversion of succinic acid to fumaric.
The CAC is called a cycle because the starting molecule, oxaloacetate is regenerated at the end of the cycle.
It is also known as Krebs cycle. This is actually a part of a huge process called cellular respiration. The citric acid cycle captures the energy stored in the chemical bonds of acetyl CoA (processed glucose) in a step-by-step process, trapping it in the form of high-energy intermediate molecules.
NADH:- It is an energy shuttle that delivers high energy electrons to the electron transport chain where they eventually get to power the production of 2 to 3 ATP molecules.
FADH:- This is another energy shuttle that carries high energy electrons to the electron transport chain, where they will ultimately drive production of 1 to 2 ATP molecules.

What type of human cells contain a half set of chromosomes?
Corticotropin-releasing hormone (CRH)-immunoreactive (IR) axon varicosities target a subset of growth hormone-releasing hormone (GHRH)-IR neurons in the human hypothalamus
It is well accepted that one of the key causes stifling growth is stress.
Previous research has shown that the catecholaminergic and neuropeptide Y (NPY) systems, which are involved in the activation of stress-related neural circuits, regulate growth hormone (GH) release through altering GHRH production.
Catecholaminergic and NPY-immunoreactive (IR) axon varicosities do, in fact, abut the surface of GHRH neurons, creating connections. These juxtapositions appear to be actual synapses and might be the morphological foundation of stress's influence on development.
Aside from catecholamines and NPY, there is a large body of evidence suggesting corticotropin-releasing hormone (CRH), a significant stress hormone, regulates GH secretion.
The architecture of these CRH-GHRH juxtapositions shows that, among other neurotransmitters/neuromodulators, CRH regulates development via direct synaptic processes via influencing hypothalamic GHRH production.

ConditioningAccording to the "learning" or conditioning theory of behavioral psychology, a person or an animal's response to an object or event can be changed. Operant Conditioning, which Skinner developed from the most well-known variation of this, is a result of the Classical Conditioning method. The experiments of Ivan Pavlov, who decided to study conditioning after learning that his canine subjects began to salivate not only when meat powder was presented to them, but more importantly, when the person who was feeding them came into proximity with them, provided evidence for this mode of learning. The dogs unintentionally learned through classical conditioning to link the person giving them food with the meal itself and responded similarly to the feeders as a result.

A large area undergoes the same amount of metamorphism. All rock reach the same metamorphism grade. However, after the metamorphism some rocks are marble and some rocks are slate. Why?
The only explanation in this situation is that the parent rocks of the marble and slate were different. This indicates that the region once held both shale and limestone before metamorphism.
In reference to rocks, it denotes those that have undergone metamorphism—rocks that may have started as sedimentary, igneous, or another type of metamorphic rock but has since undergone "recrystallization" and taken on an entirely new form—under new temperature and pressure conditions.
For instance, when limestone is heated and compressed, it changes into marble, a more coarsely crystalline and occasionally banded rock.
When shale, a clay-rich, soft rock, is compressed, slate, a tougher rock, is created.
The alterations are frequently even more remarkable, resulting in the formation of new minerals, including garnet, mica, and tourmaline (as seen in schist).

What do having the measles and being vaccinated against the measles have in common?
They are both forms of active immunity.
What is active immunity?When our own immune system defends us against a pathogen, this is known as active immunity. Our immune system develops active immunity when exposed to a potential disease-causing substance (i.e., pathogen). Active immunity is crucial since it not only "fights off" these pathogens but also lasts a very long period in the form of immunologic memory.
B and T lymphocytes with the ability to recognize a particular pathogen make up immunologic memory. These cells circulate at low levels in human bodies, but if they become "activated" by encountering the pathogen while traveling, they rapidly begin to multiply and send signals to other immune system components to do the same. There are two reasons memory cells are important. They first help our immune systems react swiftly. The immune response is prepared the moment the infection is contacted since they are secondly pathogen-specific.
