The National Board of Medical Examiners in the USA also provides progress testing in various countries [10] [11] The feasibility of an international approach to progress testing has been recently acknowledged [12] and was first demonstrated by Albano et al. [13] in 1996, who compared test scores across German, Dutch and Italian medical schools.
[1] Regulation of biological processes occurs when any process is modulated in its frequency, rate or extent. Biological processes are regulated by many means; examples include the control of gene expression, protein modification or interaction with a protein or substrate molecule.

An examination (exam or evaluation) or test is an educational assessment intended to measure a test-taker's knowledge, skill, aptitude, physical fitness, or classification in many other topics (e.g., beliefs). [1] A test may be administered verbally, on paper, on a computer, or in a predetermined area that requires a test taker to demonstrate ...
These rates are likely to differ in non experimental settings. The models also require that N t μ >> 1 where N t is the total number of organisms. This assumption is likely to hold in most realistic or experimental settings. Luria and Delbrück [5] estimated the mutation rate (mutations per bacterium per unit time) from the equation
Light micrograph of a moss's leaf cells at 400X magnification. The following outline is provided as an overview of and topical guide to cell biology: . Cell biology – A branch of biology that includes study of cells regarding their physiological properties, structure, and function; the organelles they contain; interactions with their environment; and their life cycle, division, and death.
Evolutionary progress as a tree of life. Ernst Haeckel, 1866 Lamarck's two-factor theory involves 1) a complexifying force that drives animal body plans towards higher levels (orthogenesis) creating a ladder of phyla, and 2) an adaptive force that causes animals with a given body plan to adapt to circumstances (use and disuse, inheritance of acquired characteristics), creating a diversity of ...
Non-invasive micro-test technology (NMT) is a scientific research technology used for measuring physiological events of intact biological samples. NMT is used for research in many biological areas such as gene function , plant physiology , biomedical research , and environmental science .
