DNA
Prokaryotic cells LACK
ACTG
Letters associated with DNA
Antibiotic resistent bacteria
Does not fall under Domain Eukarya
Unequal Reproductive Success
Darwin's inescapable conclusion
Properties associated with life
Example: order, regulation, reproduction, evolution, response to enviornment
Biology
study of life

Natural selection tends to act at the level of
Population
proton
positively charged particle
neutron
neutral particle of an atom
electron
negatively charged particle
atomic number
the number of protons in the nucleus of an atom
mass number
the number of protons plus the number of neutrons it contains
atom
basic unit of matter
2 forces causing chemical bonding
sharing of electrons, opposite electrical charges
ionic bond
a chemical bond in which one atom loses an electron to form a positive ion and the other atom gains to electron to form a negative ion, and the opposite charges cause them to combine
covalent bond
a bond formed when atoms share one or more pairs of electrons
