A prokaryote is a unicellular organism that lacks a membrane-bound nucleus (karyon),
mitochondria, or any other membrane-bound organelle
A eukaryote is a unicellular organism that has membrane-bound oragnelles.
Bacteria are prokaryotes
A partnership is an association of individuals who operate a business for profit. This does not necessarily
mean that there must be a profit- just that the profit is the objective. Professional partnerships can vary in
size from 2 partners to thousands.
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a
sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T),
guanine (G) and cytosine (C). The order of these bases is what d

Atomic radius is the distance from the centre of an atom to the outermost electrons, expressed in
picometers (10-12 m).
Effective nuclear charge is the net force experienced by an electron in an atom due to the
positively charged nucleus.

The nuclei of atoms contains positively charged protons and neutral neutrons. Atomic number is the
number of protons in the nucleus and given the symbol Z. The atomic mass number, A, represents the
total amount of protons and neutrons.

Metabolism and Cellular Energy
the basic characteristics of any living organism is that it grows, repair itself, reproduces,
respires, and eventually dies
to do those things, an organism requires energy
