BIOLOGY 181 TEST PAPER 2025/2026 QUESTIONS AND
ANSWERS GRADED A+
✔✔Control Group and Experimental Group - ✔✔In an experiment, the group that is not
exposed to the treatment; contrasts with the experimental group and serves as a
comparison for evaluating the effect of the treatment.
✔✔Modeling - ✔✔Another way to gain scientific knowledge without a controlled
experiment. Scientific models represent the real world in a smaller and simpler fashion.
✔✔Scientific Theories - ✔✔With repeated testing, some hypotheses may eventually
become scientific theories. A scientific theory is broad explanation that is widely
accepted as true
✔✔Scientific Laws - ✔✔General rules that summarize how nature behaves.
✔✔Bio- inspiration (Biomimicry or biomimetrics) - ✔✔Deriving inspiration from nature's
design, processes, and systems to produce innovative solutions to human problems.
✔✔Carbohydrates - ✔✔The main fuel source for most things.
✔✔Carbohydrate monomer - ✔✔monosaccharide
✔✔Carbohydrate polymer - ✔✔polysaccharide
✔✔Two monosaccharides joined together - ✔✔disaccharide
✔✔Lipids - ✔✔Energy-rich organic compounds, such as fats, oils, and waxes, that are
made of carbon, hydrogen, and oxygen. They are involved in energy storage,
membrane formation, and steroid function.
✔✔True or False: Lipids lack a monomer unit - ✔✔True
✔✔True or false: Lipids are hydrophobic - ✔✔true
✔✔Triglycerides - ✔✔A type of lipid. When people calories are unused, triglycerides
convert calories into fat which is stored in the fat cells called lipocytes.
✔✔Saturated Fats - ✔✔A type of lipid in which the fatty acid chains have all single
bonds.
✔✔Unsaturated fats - ✔✔Unsaturated fatty acids have one or more double bonds.
✔✔Ratio of Carbohydrates - ✔✔1:2:1
