142
Ornithology is the scientific study of which group?
Answer:
Birds
Ornithology focuses on birds, including their behavior, evolution, and conservation. Researchers study flight, song, and migration. Fungi are studied in mycology, shells in conchology, and soils in pedology. Therefore, birds is correct.
143
Apiculture is the science dealing with which activity?
Answer:
Beekeeping
Apiculture involves the management of honeybees for honey, wax, and pollination. It includes hive maintenance and bee health. Wood engraving is xylography, stamp collecting is philately, and codes belong to cryptology. Hence, beekeeping is correct.
144
Entomology is the branch of zoology that studies what?
Answer:
Insects
Entomology is devoted to the scientific study of insects, including their classification and ecology. It informs agriculture and disease control. Birds are covered by ornithology, fish by ichthyology, and trees by dendrology. Therefore, insects is correct.
145
Cytology focuses on the study of which of the following?
Answer:
Cells
Cytology is the study of cell structure and function. It investigates cell organelles and processes like division. Seismology studies earthquakes, numismatics studies coins, and hyetology studies rainfall. Hence, cells are correct.
146
Acoustics is best described as the science of what?
Answer:
Sound
Acoustics deals with the generation, transmission, and reception of sound. It covers phenomena such as resonance, noise control, and room acoustics. Shells are studied in conchology, handwriting in graphology, and prison management in penology. Therefore, sound is correct.
147
Which discipline is concerned with the study of the Earth?
Answer:
Geology
Geology studies the Earth’s materials, structure, and processes. It includes minerals, rocks, plate tectonics, and geologic time. Cytology focuses on cells, philology on languages and texts, and dendrology on trees. Thus, geology is the correct field.
148
Hematology is the branch of science that studies which subject?
Answer:
Blood
Hematology examines blood, its components, and related disorders like anemia and leukemia. It encompasses physiology and pathology of blood and blood-forming organs. Option B is ornithology, Option C is mycology, and Option D is numismatics. Hence, blood is correct.
149
Paleontology focuses on the study of what?
Answer:
Fossils
Paleontology investigates fossils to reconstruct past life and environments. It analyzes preserved remains and traces to infer evolution and Earth’s history. Rainfall is covered by hyetology, soil management by agronomy, and earthquakes by seismology. Therefore, fossils are the central subject of paleontology.
150
Which description best classifies psoriasis?
Answer:
A chronic autoimmune skin disease
Psoriasis is an immune-mediated dermatologic condition characterized by plaques and scaling. It is not a cognitive or educational disorder, so Option A is incorrect.
