Biology and Science Terminology Questions
-
bacteria
-
bacterial plasma membrane
-
bacterial pillus
-
bacterial capsule
A
Correct answer
Explanation
Bacteriology is the study of bacteria. It comprises the identification, classification and characterisation of bacterial species.
-
Ornithology
-
Cambrogenics
-
Cryogenics
-
Embryology
C
Correct answer
Explanation
Cryogenics is the branch of physics and engineering that deals with the production and study of very low temperatures (typically below -150°C or 123K). It involves the study of how materials behave at these temperatures and their technological applications like superconductivity, liquid gases storage, and cryopreservation. The other options are unrelated fields.
-
Palaeontology
-
Petrology
-
Seismology
-
Bathymetry
A
Correct answer
Explanation
Paleontology is the scientific study of fossils and the history of life on Earth through examination of plant and animal remains preserved in rocks. Petrology studies rocks, seismology studies earthquakes, and bathymetry measures underwater depth.
-
paleontology
-
homology
-
phrenology
-
peunology
A
Correct answer
Explanation
Paleontology is the scientific study of fossils, including fossilized plants, animals, and other organisms. It helps us understand evolution and prehistoric life. The other options: homology (similarities from common ancestry), phrenology (discredited skull theory), and peunology is not a recognized scientific term.
-
Radiology
-
Rheology
-
Seismology
-
Craniotomy
B
Correct answer
Explanation
Rheology is the study of the deformation and flow of matter, including liquids, gases, and soft solids. It examines how materials respond to applied forces. The other options: Radiology (medical imaging), Seismology (earthquakes), Craniotomy (surgical procedure).
-
Mycology
-
Rheumatology
-
Toxicology
-
Pedology
D
Correct answer
Explanation
Pedology is the branch of soil science dealing with the origin, classification, and mapping of soils in their natural environment. The other options relate to different biological/medical fields: Mycology studies fungi, Rheumatology deals with rheumatic diseases, and Toxicology examines the effects of chemicals on living organisms. Pedology comes from Greek 'pedon' meaning soil or earth.
-
Detective work
-
physiology and medicine
-
leprosy control
-
psychology
D
Correct answer
Explanation
Sigmund Freud is universally recognized as the founding figure of psychoanalysis and psychology. He developed theories about the unconscious mind, dream interpretation, and psychosexual development. His work revolutionized our understanding of human psychology and mental processes.

-
Pedology
C
Correct answer
Explanation
Palynology is the study of pollen grains.
-
Myology
-
Syndesmology
-
Angiology
-
Splanchnology
B
Correct answer
Explanation
Syndesmology is defined as the study of the structure, function and diseases of the joints present in the human body.
-
ecology
-
forest ecology
-
autoecology
-
synecology
-
plant ecology
C
Correct answer
Explanation
The branch of ecology that deals with the biological relationship between an individual organism or an individual species and its environment.
-
Astronomy
-
Taxonomy
-
Anatomy
-
None of these
B
Correct answer
Explanation
Taxonomy is the branch of science concerned with classification, specifically of organisms. The term comes from Greek 'taxis' (arrangement) and 'nomia' (method). Astronomy studies celestial bodies, and anatomy deals with body structure.
-
genetics
-
biology
-
biotechnology
-
botany
A
Correct answer
Explanation
Genetics is the specific branch of biology that studies heredity (the passing of traits from parents to offspring) and variation (the differences that exist between individuals). While biology is the broader study of life, biotechnology applies biological knowledge to technology, and botany specifically studies plants - genetics is the precise term for the study of heredity and variation across all organisms.
-
Pharmacodynamcis
-
Pharmacokinetics
-
Pharmacophore
-
All of the above
-
phycology
-
chronology
-
zoology
-
phrenology
A
Correct answer
Explanation
Phycology is the branch of biology that studies algae, including their physiology, structure, ecology, and classification. Chronology is the science of arranging events in order, zoology studies animals, and phrenology is the pseudoscience of determining character from skull shape.
-
Entomology
-
Soil biology
-
Pedology
-
Aerobiology
C
Correct answer
Explanation
Pedology (from Greek pedon = soil) is the branch of soil science that studies soil in its natural environment - its formation, classification, morphology, and geographic distribution. Entomology studies insects, aerobiology studies airborne organic particles, and soil biology is a subfield of pedology.
