EXAM 1 BIOLOGICAL FOUNDATIONS 57 QUESTIONS
WITH VERIFIED ANSWERS 2025/2026
A material that donates energy to reactants in order to reduce their activation
energy - CORRECT ANSWER Catalysts
A process in which a protein unravels, losing its specific structure and hence
function; can be caused by changes in pH or salt concentration or by high
temperature - CORRECT ANSWER Denaturation
Organisms are highly organized and coordinated structures that consist of one or
more cells
Simple, single-celled organisms are complex- atoms, molecules, organelles, etc.
Multicellular organisms- tissues work to create organs - CORRECT ANSWER Order
Organisms respond to diverse stimuli
Movement toward stimulus is positive, while away is negative - CORRECT ANSWER
Sensitivity/response to stimuli
Single-celled organisms reproduce duplicating DNA then dividing it equally as cell
divides to two new cells
Multicellular organisms produce germline cells that will form genes containing
DNA passed to organism's offspring - CORRECT ANSWER Reproduction
Organisms grow/develop following instructions coded for by genes
, Genes provide instructions to direct cellular growth - CORRECT ANSWER Growth
and Development
Coordinate internal functions, respond to stimuli, and cope with stress - CORRECT
ANSWER Regulation
Conditions such as correct temp., pH, concentration of diverse chemicals, etc.
change from one moment to next
The ability of organism to maintain constant internal conditions - CORRECT
ANSWER Homeostasis
All organisms use source of energy for metabolic activities
Organisms capture energy from sun and convert to chemical energy
(photosynthesis) or they use chemical energy in molecules they take in as food
(cellular respiration) - CORRECT ANSWER Energy Processing
smallest and most fundamental unit of matter- contains nucleus - CORRECT
ANSWER Atom
two or more atoms joined together - CORRECT ANSWER Molecule
large molecules that are formed by polymerization (DNA) - CORRECT ANSWER
Macromolecule
small structures that exist within cells - CORRECT ANSWER Organelle
