Advanced Placement (AP) Biology (also known as AP Bio) is an Advanced Placement biology course and exam offered by the College Board in the United States. For the 2012–2013 school year, the College Board unveiled a new curriculum with a greater focus on "scientific practices".
Influenced by 19th century positivism [5] and Charles Darwin's evolution, for both Friedrich Engels and Karl Marx, the idea of uncertainty and chance in social dynamics (and thus unintended consequences beyond results of perfectly defined laws) was only apparent, (if not rejected) since social actions were directed and produced by deliberate human intention.
This is an example of a locally acting (negative feedback) mechanism. An example of upregulation is the response of liver cells exposed to such xenobiotic molecules as dioxin . In this situation, the cells increase their production of cytochrome P450 enzymes , which in turn increases degradation of these dioxin molecules.
The pre-testing effect, also known as errorful generation or pre-questioning, is a related but distinct category where testing material before the material has been learned appears to lead to better subsequent learning performance than would have been the case without the pre-test, provided that feedback is given as to the correct answers once ...
The collective goal is to contribute excellent biology diagrams to the Commons and to corresponding Wikipedia articles. This is done as part of an Advanced Placement Biology course. The lead editor is Chris Packard. This project is inspired by the 2009 Wikipedia AP Biology Project. There are many basic and important diagrams missing from ...

Auditory feedback in the form of periodic audio signals was found to have a significant improvement on the gait of patients, with several explanations proposed. One model argues that auditory feedback acts as an additional information channel for the motor systems, thereby decreasing the onset of motor faults and refining the gait of patients. [37]
Secondary feedback loops interact with this primary feedback loop. CLOCKWORK ORANGE (CWO) binds the E-boxes to act as a direct competitor of CYC-CLK, therefore inhibiting transcription. PAR-DOMAIN PROTEIN 1 ε (PDP1ε) is a feedback activator and VRILLE (VRI) is a feedback inhibitor of the Clk promoter, and their expression is activated by dCLK ...
