Combined Science results in two GCSEs. Those with GCSEs in Combined Science can progress to A Levels in all of the three natural science subjects. Prior to this, around 1996, Combined Science GCSEs were available as an alternative to three separate Sciences for many exam boards. Combined Science consists of either Higher Tier (HT) or Foundation ...

The General Certificate of Secondary Education (GCSE) is an academic qualification in a range of subjects taken in England, Wales and Northern Ireland, having been introduced in September 1986 and its first exams taken in 1988. State schools in Scotland use the Scottish Qualifications Certificate instead. However, private schools in Scotland ...
According to Noether's theorem, the conservation of energy is a consequence of the fact that the laws of physics do not change over time. [6] Thus, since 1918, theorists have understood that the law of conservation of energy is the direct mathematical consequence of the translational symmetry of the quantity conjugate to energy, namely time.
In cellular biology, active is the movement of molecules or ions across a cell membrane from a region of lower concentration to a region of higher concentration —against the concentration gradient. Active transport requires cellular energy to achieve this movement. There are two types of active transport: primary active transport that uses ...
Bioenergetics is a field in biochemistry and cell biology that concerns energy flow through living systems. [1] This is an active area of biological research that includes the study of the transformation of energy in living organisms and the study of thousands of different cellular processes such as cellular respiration and the many other metabolic and enzymatic processes that lead to ...
