What is an element?
A pure substance is made of only one type of atom, like neon or gold.
100
What are control variables?
In an experiment, these are the factors you keep the same to make it a fair test.
100
What are metals?
These elements, found on the left and middle of the table, are good conductors of heat and electricity.
100
What is the function of red blood cells
carry oxygen around the body
200
What is lactic acid?
The waste product builds up in muscles during vigorous exercise when there's not enough oxygen.
200
What is a mixture? Give three examples of mixtures
Substances that are mixed but not chemically bonded.
Examples: Salt water, air, and granite.
200
What energy transfer occurs in the image below
When a battery powers a bulb, energy is transferred from a chemical store to light energy (a useful store).
200
The atomic number on the periodic table is the amount of this particle in an atom.
What is a proton?
200
What is a joint?
The place where two or more bones meet.
300
What is a Punnett square?
This square diagram is used to predict the probability of different genotypes in offspring.
300
What are compounds? Give two examples
Pure substances formed by chemically combined elements.
Examples: carbon dioxide, water 
300
What energy transfer does the image below show?
Chemical energy to heat energy.
300
What is a tendon?
The tough, elastic tissue that connects muscle to bone.
300
What is meant by contract (pull)?
When muscles work in pairs to move bones by pulling.
400
What is a dominant allele?
An allele that codes for a characteristic, even if there's only one copy present.
400
What is malleable?
A property of metals like gold or copper that means they can be hammered or rolled into shape.
400
What energy transfer does the image below show?
Electric energy to sound and light energy
400
The reactivity of the elements increases as you move down this group.
What is group 1/alkali metals?
400
what is anaerobic respiration and why do we need it?
A type of respiration that converts glucose into lactic acid and creates energy when there is a lack/no oxygen
500
What is the function of the lungs?
This organ's main function is gas exchange, getting oxygen into the blood and removing carbon dioxide.
500
What is rusting?
The name for the corrosion of iron, which requires oxygen and water.
500
What is the law of conservation of energy?
The law that states energy cannot be created or destroyed, only transferred or stored.
500
This non-toxic element can be commonly found at parties.
What is Helium?
