REVIEW

All the non-living matter in an

environment.Abiotic

BioticAll the living matter in

an environment.

Amino acid sequenceThe order of

amino acids in a protein or

peptide chain.

The primary structure

determines the protein type

Protein

An organic compound that is made of one or more chains of amino acids.

Is a principal component of all cells

Protein

Each bead is a small amino acid. The amino

acids join to make different proteins.

Proteins are sometimes described as long necklaces with different colored beads.

Antoine Lavoisier

French chemist know as the father

of modern chemistry

AcceleratorA substance that speeds up a chemical reaction

AcceleratorWhen you push on the car accelerator the car goes faster.

Albert Einstein

(March 14, 1879 - April 18, 1955)A theoretical physicist, born in Germany, who is widely regarded as the greatest

scientist of the 20th century. He proposed the theory of relativity and also made

major contributions to the development of quantum mechanics, statistical

mechanics, and cosmology.

Albert Einstein

His famous equation that the energy of a body at rest (E)

equals its mass (m) times the speed of light (c) squared:

Atomic bombIts violent explosive power is due to the sudden release of energy.

The energy is a result from splitting the nuclei of elements by

neutrons in a very rapid chain reaction

Atomic bomb

John Dalton

English chemist and physicist who formulated atomic theory and the law

of partial pressures

Atomic theory

A theory that states that all matter is composed of tiny particles called atoms

Atomic configuration

The arrangement of atoms or groups in a molecule

Atomic massThe average mass of all

the known isotopes of an element

Atomic numberThe number of protons that an atom contains

ElectronA subatomic particle in an atom that is negatively charged and

occupies an energy level outside the nucleus

ProtonPositively charged particle in the nucleus of an atom. Has

a positive charge.

Neutron A subatomic particle found in the nucleus of an atom. It has

no charge = Neutral.

Alfred Wegener

German meteorologist and geophysicist who formulated

the first complete statement of the continental drift hypothesis

Plate tectonicsTheory that Earth’s crust and upper mantle are broken into plates that float and move around on a plastic like layer of the mantle

Daniel Gabriel Fahrenheit

German physicist who invented the mercury

thermometer and developed the scale of temperature that bears

his name

Fahrenheit

A scale used to measure temperature

Water freezes at 32 degrees Fahrenheit

Big Bang theoryThe theory that the universe

originated from the cataclysmic explosion of a small volume of

matter at extremely high density and temperature.
