prokaryotic cell - answer does not have an organelle
Eukaryotic cells - answerhas organelles
The three domains of life are - answerBacteria ( unicellular prokaryote), Archaea
(unicellular prokaryote), Eukarya (unicellular & multicellular eukaryotes)
Prokaryotic and Eukaryotic both have - answercell membrane, cytoplasm, genetic
material (dna)
Energy - answerthe ability and capacity to do work
organelles - answermembrane bound structures with specific structures (ex: nucleus)
Viruses are - answernonliving
living things respond to a - answerstimulus
Homeostasis - answerto maintain a set point
valence electrons - answerelectrons in the outermost shell
buffer system - answerresist changes in pH (blood)
covalent bond - answeratoms share a pair of electrons (ex; water)
hydrogen bonds - answerwhen one molecule loosely associates with another molecule
through a weak interaction
ionic bonds - answerwhen one atom transfers electrons to another (ex; salt)
3 parts of DNA are - answerphosphate, pentose sugar, and a base
Proteins are made up of - answeramino acids
what happens when you change the shape of an amino acid? - answeryou change the
function of it
DNA dictates the order of - answeramino acids
, what is the work of the cell? - answerchemical and transport work
functional groups add something to the - answercore compound
Electronegativity - answerone molecule has a greater pull than another molecule
asymmetrical pull - answerpolar molecule (stronger pull)
symmetrical pull - answernonpolar molecule (equal pull)
Organic compounds contain - answercarbon, hydrogen, oxygen
monomer - answerone unit (ex; glucose)
polymer - answermany units (ex: proteins)
amino acid structure - answera carboxyl group, amine group, and R group
primary structure of protein - answerlinear sequence of amino acids
secondary structure of protein - answerhydrogen interaction
