Red Giant
A star that has expanded and cooled, resulting in it becoming red and much larger than it was before it expanded.
1 of 16
Respiration
The process by which food molecules are broken down to release energy to cells.
2 of 16
Ribosome
The site of protein synthesis in a cell
3 of 16
Speciation
The formation of new species
4 of 16
White Dwarf
A star that has collapsed from the giant stage to become much hotter and denser than it was
5 of 16
Gamma Radiation
Electromagnetic radiation emitted from unstable nuclei in radioactive substances
6 of 16
Genetic Disorder
Disease which is inherited
7 of 16
Half Life ( of a radioactive isotope )
Average time taken for the number of nuclei of the isotope of mass of the isotope in a sample of halve
8 of 16
Meiosis
The two stage process of cell division which reduces the chromosome number of the daughter cells. It is involved in making the gametes for sexual reproduction.
9 of 16
Mitosis
Asexual cell division where two identical cells are formed.
10 of 16
Nuclear Fission
The process in which certain nuclei (uranium- 235 and plutonium-239) split into two fragments, releasing energy and two or three neutrons as a result
11 of 16
Catalyst
A substance which speeds up a chemical reaction. At the end of the reaction the catalyst remains chemically unchanged.
12 of 16
Chain Reaction
Reactions in which one reaction causes further reactions which in turn causes further reactions.. A nuclear chain reaction occurs when fission neutrons cause further fission so more fission neutrons are released.These go on to produce further fission
13 of 16
Super Giant
A massive star that becomes larger than a giant star when fusion of helium nuclei commences.
14 of 16
Supernova
The explosion of a massive start after fusion in its core ceases and the matter surrounding its core collapses onto the core and rebounds.
15 of 16
Lipase
Enzyme which breaks down fats and oils into fatty acids and glycerol
