BIOLOGY 1201 ACTUAL EXAM PAPER 2026
COMPLETE QUESTIONS WITH SOLUTIONS
GRADED A+
◉ Theory
Answer: broader in scope than a hypothesis and can lead to a new
testable hypothesis; supported by a large body of evidence in
comparison to a hypothesis
◉ Deductive
Answer: Testing what you think is true; Design, Test, Conclusion
◉ Inductive
Answer: making observations and solution from that observation;
All observations have the same result.
◉ Valence
Answer: Outer shell of electrons; the number of unpaired electrons
in the valence shell of an atom is generally equal to its valence (the #
of covalent bonds it can form)
, ◉ Atomic mass
Answer: the atom's total mass, which can be approximated by the
mass number
◉ Mass number
Answer: the sum of protons and neutrons in the nucleus
◉ Atomic number
Answer: the number of protons in an element
◉ Isotopes
Answer: two atoms of an element that differ in the number of
neutrons
◉ Radioactive isotopes
Answer: decay spontaneously, giving off particles and energy
◉ Hydrogen bonds
Answer: forms when a hydrogen atom covalently bonded to one
electronegative atom is also attracted to another electronegative
atom
◉ covalent bonds
