General Biology Exam Questions & Answers |
Complete Study Guide (High Accuracy) updated 2025
1. quantitative observations
measuring something with numbers
2. homeostasis
Balancing human or any living organisms
3. Diffusion
The passive movement of particles from an area of high concentration to low
concentration. This happens along a concentration gradient
4. Osmosis
A passive movement of water molecules through a semi permeable
membrane. Water moves from an area of low solute concentration to high
solute concentration
5. Active Transport
An active movement where an input of energy is required. Particles move
from low concentration to high concentration
6. Facilitated Diffusion
A passive movement of particles from high to low concentration through a
protein channel in a cell.
,7. Isotonic Solution
The same concentration of dissolved substances. Water in = water out.
8. Hypertonic Solution
Higher concentration of solutes outside cell than inside
9. Plasmolyse
When a cell has shrunk
10.Hypotonic Solution
A cell has more solute inside than outside.
11.Turgid
Cell may explode under pressure due to a hypotonic solution.
12.Exocytosis
Movement out of a cell
13.Endocytosis
Movement into a cell
, 14.Lysosome
A vesicle that contains destructive/digestive chemicals
15.Pinocytosis
A form of endocytosis where a cell engulfs liquid into the cell.
16.Phagocytosis
A form of endocytosis where a cell engulfs solids into a cell
17.Scientific question
Questions that can be answered by using experiments and factual reasoning.
18.Biology
The study of living organisms and how they function.
19.Scientific Method
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.
