STANBRIDGE biology Exam 1
Question and answers correctly
solved 2025/2026
1. What are the 4 life molecules (organic compounds found in living things)? - correct answer
✔Protiens, carbohydrates, lipids, nucleic Acids
. Which 4 elements make up the majority of life molecules? - correct answer ✔Carbon, hydrogen,
nitrogen, oxygen
. How does atomic number and atomic mass compare to subatomic particles - correct answer ✔Atomic
number = number of protons in nucleus
Atomic mass = # of protons & neutrons in nucleus
Subatomic particles = number of protons in nucleus = atomic mass
. What's the difference between and ion and an isotope - correct answer ✔Ions are formed from the
loss or gain of electrons
Isotopes are change in neutrons
What's the difference between an acid and a base - correct answer ✔Acid is high hydrogen
concentration, a base is low hydrogen concentration
What's the difference between hypertonic and hypotonic solution - correct answer ✔Hypertonic
concentration of salt is higher in the cell
Hypotonic concentration of salt is lower in the cell
An acid - correct answer ✔Adds hydrogen ions to a solution
, The primary building block (monomer) of proteins is - correct answer ✔an amino acid
An ion could be - correct answer ✔Atom who has lost or gained electrons
Atom who has a positive or negative charge
cellular respiration formula - correct answer ✔C6H12O2 + 6O2 ------> 6CO2 + 6H20 + 36 (ATP)
What's the difference between hydrolysis and dehydration synthesis - correct answer ✔Hydrolysis is
the release of energy
Dehydration requires energy
Nucleolus - correct answer ✔produces ribosomes
Mitochondria - correct answer ✔Generate ATP through aerobic respiration
Ribosomes - correct answer ✔site of protein synthesis
Smooth ER - correct answer ✔Synthesizes fatty acids and hormones
Rough ER - correct answer ✔Makes proteins
Golgi body - correct answer ✔Transport vesicles and moves proteins
Vacuole - correct answer ✔Store food,waste and water for cells
Cytoskeleton - correct answer ✔Transport & sx of the cell and organelles
