Tests of sufficiency in biology are used to determine if the presence of an element permits the biological phenomenon to occur. In other words, if sufficient conditions are met, the targeted event is able to take place. However, this does not mean that the absence of a sufficient biological element inhibits the biological event from occurring.
Serial passage is the process of growing bacteria or a virus in iterations. For instance, a virus may be grown in one environment, and then a portion of that virus population can be removed and put into a new environment.
An inquest is a judicial inquiry in common law jurisdictions, particularly one held to determine the cause of a person's death. [1] Conducted by a judge, jury, or government official, an inquest may or may not require an autopsy carried out by a coroner or medical examiner. Generally, inquests are conducted only when deaths are sudden or ...
This is done by comparing concentrations to lethal limits. The most common samples analyzed are blood, urine, kidney, liver, and brain. The samples are usually put through various tests, but the most common instrument used to quantify and determine a substance is gas chromatography-mass spectrometry (GC-MS).
Real-life crime scene investigators and forensic scientists warn that popular television shows do not give a realistic picture of the work, often wildly distorting its nature, and exaggerating the ease, speed, effectiveness, drama, glamour, influence and comfort level of their jobs—which they describe as far more mundane, tedious and boring.
A coroner must summon a jury for an inquest if the death was not a result of natural causes and occurred when the deceased was in state custody (for example in prison, police custody, or whilst detained under the Mental Health Act 1983); or if it was the result of an act or omission of a police officer; or if it was a result of a notifiable accident, poisoning or disease.

Variants of the competition assay are useful for measuring the specificity of binding and for measurement of association and dissociation kinetics. Thus, EMSA might also be used as part of a SELEX experiment to select for oligonucleotides that do actually bind a given protein. [citation needed]
Mesocosm experiments also tend to include replication of different treatment levels. Manipulating something can give an idea as to what to expect if something were to occur in that ecosystem or environment. [2] For indoor mesocosms, growth chambers grant greater control over the experiment. [2]
