BIO 252 EXAM SCRIPT UPDATED
COMPLETE QUESTIONS WITH ACCURATE
ANSWERS
●● Osmosis
Answer: A passive movement of water molecules through a semi
permeable membrane. Water moves from an area of low solute
concentration to high solute concentration
●● Active Transport
Answer: An active movement where an input of energy is required.
Particles move from low concentration to high concentration
●● Facilitated Diffusion
Answer: A passive movement of particles from high to low
concentration through a protein channel in a cell.
●● Isotonic Solution
Answer: The same concentration of dissolved substances. Water in =
water out.
●● Hypertonic Solution
Answer: Higher concentration of solutes outside cell than inside
,●● Plasmolyse
Answer: When a cell has shrunk
●● Hypotonic Solution
Answer: A cell has more solute inside than outside.
●● Turgid
Answer: Cell may explode under pressure due to a hypotonic solution.
●● Exocytosis
Answer: Movement out of a cell
●● Endocytosis
Answer: Movement into a cell
●● Lysosome
Answer: A vesicle that contains destructive/digestive chemicals
●● Pinocytosis
Answer: A form of endocytosis where a cell engulfs liquid into the cell.
,●● Phagocytosis
Answer: A form of endocytosis where a cell engulfs solids into a cell
●● Scientific question
Answer: Questions that can be answered by using experiments and
factual reasoning.
●● Biology
Answer: The study of living organisms and how they function.
●● Scientific Method
Answer: A method of procedure that has characterized natural science
since the 17th century, consisting in systematic observation,
measurement, and experiment, and the formulation, testing, and
modification of hypotheses.
●● Hypothesis
Answer: 1st part of the scientific method
●● experimental design
Answer: Experimental design refers to how participants are allocated to
the different conditions (or IV groups) in an experiment.
, ●● variable
Answer: factors that are kept constant or unchanging.
●● observation
Answer: The process of studying of something to gain information.
●● inference
Answer: A conclusion made up of facts and inferring knowledge.
●● conclusion
Answer: The final ending or idea of a process
●● prediction
Answer: A statement about the hypothesis
●● qualitative observations
Answer: detailed examination with your senses only
●● quantitative observations
Answer: measuring something with numbers
●● homeostasis
