Complete Solutions
living things respond to a stimulus
Homeostasis to maintain a set point
valence electrons electrons in the outermost shell
buffer system resist changes in pH (blood)
covalent bond atoms share a pair of electrons (ex; water)
hydrogen bonds when one molecule loosely associates with another molecule through a
weak interaction

, BRCC BIO EXAM 1 Questions With
Complete Solutions
3 parts of DNA are phosphate, pentose sugar, and a base
Proteins are made up of amino acids
what happens when you change the shape of an amino acid? you change the function of it
DNA dictates the order of amino acids
what is the work of the cell? chemical and transport work
functional groups add something to the core compound
Electronegativity one molecule has a greater pull than another molecule
asymmetrical pull polar molecule (stronger pull)
