Saturation
Lipofuscin is the name given to finely granular yellow-brown pigment granules [ 1 ] composed of lipid -containing residues of lysosomal digestion. It is considered one of the aging or "wear-and-tear" pigments, found in the liver , kidney , heart muscle, adrenals , nerve cells, and ganglion cells. It is specifically arranged around the nucleus, and is a type of lipochrome . [ edit ] Formation and turnover It appears to be the product of the oxidation of unsaturated fatty acids , and may be symptomatic of membrane damage, or damage to mitochondria and lysosomes . Aside from a large lipid content, lipofuscin is known to contain sugars and metals, including mercury , aluminum , iron , copper and zinc . [ 2 ]

Multipotentiality
A limiting factor causes a population to decrease in size. A few limiting factors are food, shelter, water, space. These are not all limited to the condition of the species. Some factors may be increased or reduced based on circumstances. An example of a limiting factor is sunlight in the rain forest, where growth is limited to all plants in the under story unless more light becomes available. This decreases plants photosynthesis.

Competitive exclusion principle
In ecology , the competitive exclusion principle , [ 1 ] sometimes referred to as Gause's law of competitive exclusion or just Gause's law , [ 2 ] is a proposition which states that two species competing for the same resources, that are limited, cannot coexist if other ecological factors are constant. When one species has even the slightest advantage or edge over another, then the one with the advantage will dominate in the long term. One of the two competitors will always overcome the other, leading to either the extinction of this competitor, complete anihilation of the species, or an evolutionary or behavioral shift towards a different ecological niche . The principle has been paraphrased into the maxim " complete competitors cannot coexist ". [ 1 ] [ edit ] Experimental basisMycoplasma
Mycoplasma refers to a genus of bacteria that lack a cell wall . [ 1 ] Without a cell wall, they are unaffected by many common antibiotics such as penicillin or other beta-lactam antibiotics that target cell wall synthesis. They can be parasitic or saprotrophic . Several species are pathogenic in humans, including M. pneumoniae , which is an important cause of atypical pneumonia and other respiratory disorders, and M. genitalium , which is believed to be involved in pelvic inflammatory diseases . Mycoplasma is the smallest known cell and is about 0.1 µm in diameter. [ edit ] Origin of the name The name Mycoplasma , from the Greek mykes (fungus) and plasma (formed), was first used by Albert Bernhard Frank in 1889.Waste

Precautionary principle
The precautionary principle or precautionary approach states if an action or policy has a suspected risk of causing harm to the public or to the environment , in the absence of scientific consensus that the action or policy is harmful, the burden of proof that it is not harmful falls on those taking an act. This principle allows policy makers to make discretionary decisions in situations where there is the possibility of harm from taking a particular course or making a certain decision when extensive scientific knowledge on the matter is lacking. The principle implies that there is a social responsibility to protect the public from exposure to harm, when scientific investigation has found a plausible risk. These protections can be relaxed only if further scientific findings emerge that provide sound evidence that no harm will result. In some legal systems, as in the law of the European Union , the application of the precautionary principle has been made a statutory requirement. [ 1 ]Systematic error
Systematic errors are biases in measurement which lead to the situation where the mean of many separate measurements differs significantly from the actual value of the measured attribute. All measurements are prone to systematic errors, often of several different types. Sources of systematic error may be imperfect calibration of measurement instruments (zero error), changes in the environment which interfere with the measurement process and sometimes imperfect methods of observation can be either zero error or percentage error. For example, consider an experimenter taking a reading of the time period of a pendulum swinging past a fiducial mark: If their stop-watch or timer starts with 1 second on the clock then all of their results will be off by 1 second (zero error).Error
The word error entails different meanings and usages relative to how it is conceptually applied. The concrete meaning of the Latin word "error" is "wandering" or "straying". Unlike an illusion , an error or a mistake can sometimes be dispelled through knowledge (knowing that one is looking at a mirage and not at real water does not make the mirage disappear). For example, a person who uses too much of an ingredient in a recipe and has a failed product can learn the right amount to use and avoid repeating the mistake. However, some errors can occur even when individuals have the required knowledge to perform a task correctly.Enthalpy is a measure of the total energy of a thermodynamic system . It includes the internal energy , which is the energy required to create a system, and the amount of energy required to make room for it by displacing its environment and establishing its volume and pressure . Enthalpy is a thermodynamic potential . It is a state function and an extensive quantity. The unit of measurement for enthalpy in the International System of Units (SI) is the joule , but other historical, conventional units are still in use, such as the British thermal unit and the calorie .
