HUMAN BIOLOGY 17TH EDITION ACTUAL
TEST PAPER 2026 QUESTIONS WITH
SOLUTIONS GRADED A+
◉metabolism. Answer: sum of reactions involved in life processes
◉photosynthesis. Answer: responsible for producing organic
molecules that serve as food
◉Life must:. Answer: reproduce, experience growth, develop,
acquire materials and energy from the environment, maintain
homeostasis, respond to stimuli, adapt, and have an evolutionary
history
◉Scientific Method Steps. Answer: observation, hypothesis using
inductive reasoning, experimentation, make prediction, collect and
analyse data, form a conclusion, present findings
◉matter. Answer: anything that takes up space and has mass.
composed of elements.
◉elements. Answer: basic building blocks of matter that cannot be
broken down by chemical means
,◉atoms. Answer: smallest units of an element that retain the
element's physical and chemical properties
◉molecules. Answer: 2+ atoms bonded together
◉atomic number. Answer: the number above the abbreviation
◉neutrons. Answer: uncharged subatomic particles
◉electrons. Answer: negatively charged subatomic particles that
orbit the nucleus
◉Isotopes. Answer: atoms that have the same atomic number but
different atomic mass because the number of neutrons differ
◉radioisotopes. Answer: useful in dating old objects, imaging body
organs and tissues through X-rays, and killing cancer cells
◉Ionic bonds. Answer: atoms donate or take on electrons which
results in a stable outer shell
◉anion. Answer: negative charge
, ◉cation. Answer: positive charge
◉Covalent bonds. Answer: atoms share electrons that result in a
stable outer shell
◉polar covalent bond. Answer: unequal sharing of electrons
◉non-polar covalent bond. Answer: evenly distributed electrons, no
overall charge
◉hydrogen bonds. Answer: relatively weak bonds that occur
between a hydrogen in a covalent bond and a negatively charged
atom
◉Why is water the universal solvent?. Answer: it is polar
◉hydrophilic. Answer: interact easily with water
◉hydrophobic. Answer: do not interact well with water
◉Acids. Answer: dissociate and release H+ (hydrogen ions), but
decrease pH of water.
