Edexcel (also known since 2013 as Pearson Edexcel[2]) is a British multinational education and examination body formed in 1996 and wholly owned by Pearson plc since 2005. It is the only privately owned examination board in the United Kingdom. [3] Its name is a portmanteau term combining the words education and excellence.
Ecology, evolution, and paleontology. Unsolved problems relating to the interactions between organisms and their distribution in the environment include: Paradox of the plankton. The high diversity of phytoplankton seems to violate the competitive exclusion principle. Ediacaran biota.
In trilogy, science is delivered in the three traditional parts of biology, chemistry and physics. The trilogy specification document outlines topics for each science part and practicals are specified. The trilogy GCSE exam itself is made up of six papers (each one hour and fifteen minutes): two for biology, two for chemistry, and two for physics.
However, in the Physics paper 1 exam, a topic that was stated as "Not Assessed" came up; AQA accepted the mistake and awarded all students the full 9 marks to the question. [69] Also, in 2022, a question on one of the higher Maths papers was leaked hours before students sat them. The exam board Edexcel apologised and conducted a full ...
Biomolecular engineering is the application of engineering principles and practices to the purposeful manipulation of molecules of biological origin. Biomolecular engineers integrate knowledge of biological processes with the core knowledge of chemical engineering in order to focus on molecular level solutions to issues and problems in the life sciences related to the environment, agriculture ...
Biological systems engineering. Biological systems engineering or biosystems engineering is a broad-based engineering discipline with particular emphasis on non-medical biology. It can be thought of as a subset of the broader notion of biological engineering or bio-technology though not in the respects that pertain to biomedical engineering as ...
Biological engineering. Biological engineering or bioengineering is the application of principles of biology and the tools of engineering to create usable, tangible, economically viable products. [1] Biological engineering employs knowledge and expertise from a number of pure and applied sciences, [2] such as mass and heat transfer, kinetics ...
Micro-mass cultures of C3H-10T1/2 cells at varied oxygen tensions stained with Alcian blue. A commonly applied definition of tissue engineering, as stated by Langer [3] and Vacanti, [4] is "an interdisciplinary field that applies the principles of engineering and life sciences toward the development of biological substitutes that restore, maintain, or improve [Biological tissue] function or a ...
