macromolecule
Giant covalent structure
1 of 19
main sequence star
the main stage is the life of a star during which it radiates energy because of fusion of hydrogen nuclei in its core.

mass
the quantity of matter in an object; a measure of the difficulty of changing the motion of an object (in kilogram kg)
3 of 19
mass number
the number of protons plus neutrons in the nucleus of an atom
4 of 19
mass spectrometer
a machine that can be used to analyse small amounts of a substance to identify it and to find its relative molecular mass
5 of 19
mean
the arithmatical average of a series of numbers
6 of 19
median
the middle value in a list of numbers
7 of 19
meiosis
the two-stage process of cell division which reduces the chromosome number of the daughter cells. it is involved in making gametes for sexual reproduction
8 of 19
mesophyll tissue
the tissue in a green plant where photosynthesis takes place.

mode
the number that occurs most often in a set of data
13 of 19
mole
the number of substance in the relative atomic or formula mass of a substance in grams
14 of 19
molecular formula
the chemical formula that shows the actual number of atoms in a particular molecule
15 of 19
molecular ion peak
the peak on the mass spectrum of a substance which tells us the relative molecular mass of the substance. the peak is produced by the heaviest positve ion shown on the mass spectrum
16 of 19
momentum
this equals mass (kg) X Velocity(m/s). the unit of momentum is kilogram metres per second (kg m/s)
17 of 19
multicellular organism
an organism that is made up of many different cells which work together. some of the cells are specalised for different functions in the organism
