|
Half Life
|
The average time taken for the number of radioactive atoms in a sample to half.
|
|
|
Activity
|
The number of radioactive decays each second ( Units are Bequerels, Bq)
|
|
|
Conductors
|
a material or object that allows electricity or heat to move through it
|
|
|
Insulators
|
a material that allows little or no heat, electricity, or sound to go into or out of something
|
|
|
Electrolysis
|
the process of separating a liquid into its different chemical parts by passing an electric current through it
|
|
|
Electrodes
|
one of the two points through which electricity flows into or out of a battery or other device
|
|
|
Electrolyte
|
a liquid (such as the liquid in a battery) through which electricity can pass
|
|
|
Anode
|
the positive terminal of an electrolytic cell
|
|
|
Cathode
|
the negative terminal of an electrolytic cell
|
|
|
Inheritance
|
the reception of genetic qualities by transmission from parent to offspring
|
|
|
Characteristics
|
a special quality or trait that makes a person, different from others
|
|
|
Heterozygous
|
having the two alleles at corresponding loci on homologous chromosomes different for one or more loci
|
|
|
Homozygous
|
having the two genes at corresponding loci on homologous chromosomes identical for one or more loci
|
|
|
Allell
|
one of several forms of a gene that determine alternate forms of one or more genetic traits and occupy identical places on two chromosomes
|
|
|
Pedigree
|
an ancestral line (the history of the family members in a person's or animal's past)
|
|
|
Potential Difference
|
The potential difference across a component is the work done per unit of charge in pushing charge through the component. Measured in volts.
|
|
|
Current
|
The rate of flow of electric charge (electrons). Units are AMPERES
|
|
|
EMF
|
The EMF of a cell is the work done per unit charge by the cell in driving charge around a complete circuit (including the cell itself.) Measured in Volts
|
|
|
Resistance
|
A measure of how difficult it is for a current to flow through a conductor, such as a wire. The larger the resistance, the harder it is for the current to flow. Resistance measured in Ohms.
|
|
|
Fuse
|
A thin wire that is in most electrical appliances. Designed to melt and break a circuit when the current is too high]
|
|
|
Power
|
The rate at which energ is tranformed from one form to another.
|
|
|
Watt
|
The unit of Power
|
|
|
Chromosomes
|
the part of a cell that contains the genes which control how an animal or plant grows and what it becomes
|
|
|
Allele
|
any of the alternative forms of a gene that may occur at a given locus
|
|
|
Gamete
|
one of the cells that join together to begin making a person or other creature
|
|
|
Zygote
|
a cell that is formed when an egg and a sperm combine
|
|
|
Dominant
|
causing or relating to a characteristic or condition that a child will have if one of the child's parents has it
|
|
|
Recessive
|
causing or relating to a characteristic or condition that a child will have only if both of the child's parents have it
|
|
|
Circuit breaker
|
A device designed to break the circuit if there is an electrical fault.
|
|
|
Resistor
|
An electrical device that is designed to have a very specific resistance (such as 10ohm, 5 ohms etc). The resistance of this never changes.
|
|
|
Power
|
The rate at which energ is tranformed from one form to another.
|
|
|
Watt
|
The unit of Power
|
|
|
Magnet
|
An object that has a magnetic field.
|
|
|
Magnetic field
|
A region where a magnetic material experiences a magnetic force.
|
|
|
Magnetic material
|
A material that may be magnetised or attracted to a magnet. Steel, Iron, Nickel, Cobalt are the only materials.
