  2. Developmental bioelectricity - Wikipedia

    en.wikipedia.org/wiki/Developmental_bioelectricity

    Developmental bioelectricity is the regulation of cell, tissue, and organ-level patterning and behavior by electrical signals during the development of embryonic animals and plants. The charge carrier in developmental bioelectricity is the ion (a charged atom) rather than the electron , and an electric current and field is generated whenever a ...

  3. Uniform Mark Scheme - Wikipedia

    en.wikipedia.org/wiki/Uniform_Mark_Scheme

    These modules and courseworks for a specific A Level combine to give a total UMS mark. For example, an A level Chemistry course might consist of 4 exams worth 90 UMS and 2 exams worth 120 UMS, totalling a maximum of 600 UMS. From 2008 onward, many subjects moved from 600 to 400 UMS for the A-level, and from 300 to 200 UMS for the AS.

    On 17 June 2022, AQA apologised after A-level Law Paper Two contained a 30 mark question on Rylands v Fletcher and Private nuisance, accounting for 30% of the 100 mark paper, which had not been included in the advance information. In response, AQA stated that it would "look at how students performed" after the paper had been marked and that it ...

  5. Dagger (mark) - Wikipedia

    en.wikipedia.org/wiki/Dagger_(mark)

    In biology, the dagger next to a taxon name indicates that the taxon is extinct. [23] [24] [31] In chemistry, the double dagger is used in chemical kinetics to indicate a short-lived transition state species. In genealogy, the dagger is used traditionally to mark a death in genealogical records. [32]

  6. Microbial fuel cell - Wikipedia

    en.wikipedia.org/wiki/Microbial_fuel_cell

    Microbial fuel cell (MFC) is a type of bioelectrochemical fuel cell system [1] also known as micro fuel cell that generates electric current by diverting electrons produced from the microbial oxidation of reduced compounds (also known as fuel or electron donor) on the anode to oxidized compounds such as oxygen (also known as oxidizing agent or electron acceptor) on the cathode through an ...

    The first 20 questions involve biology, the second twenty questions involve chemistry, and the final twenty questions involve physics. No time warning is given, except that tests cannot be turned in until the proctor announces that 30 minutes have passed. The questions may be answered in any order; there is no penalty for skipping questions.
