A metal which cannot displace hydrogen from acids

Base

Turns phenolphthalein solution pink and has a pH greater than 7

Turns phenolphthalein solution colorless and has a pH less than 7

Displacement Reaction

A type of reaction where one element displaces another in a compound

Metals

Elements with 1, 2, or 3 valence electrons

Non-Metals

Elements with 5, 6, 7, or 8 valence electrons

Endothermic Reaction

Reactions that absorb heat from the surroundings

Carbon dioxide production in human cells

Process that producess maximum ATP molecules per molecule of Glucose during cellular oxidation

Contraction of the left ventricle

Stage during the circulation of blood when oxygenated blood is pumped to all parts of the body

Longer small intestine

Adaptation in herbivores that helps in digestion of cellulose

Cerebellum

Part of the brain associated with posture and balance

Snails sex determination

Condition where sex is not genetically determined

Centre of Curvature

Point on a concave mirror where the angle of incidence is equal to zero

Producers

Trophic level which absorbs 1% of light energy directly from the source.

Decomposers

Replenishment of soil, waste decomposition and break down of dead remains

Hydrogen gas

A gas produced when dil. HCl is added to a substance, giving a 'pop' sound when a burning matchstick is brought near it.

Number of Chromosomes

Statements about chromosomes in germ cells restore the normal chromosomes number in a species
