General Science Quiz

Exactly 12 men have walked on the Moon, all during NASA's Apollo program between 1969 and 1972. Neil Armstrong was the first (Apollo 11, 1969), and Gene Cernan was the last (Apollo 17, 1972). These astronauts represent humanity's only direct exploration of another celestial body to date.

House flies typically live 15-30 days as adults, making 2 weeks the closest accurate answer among the options. House flies have four life stages - egg, larva, pupa, and adult - with the adult phase lasting approximately 2-4 weeks.

The Arctic Ocean is the smallest at about 14 million sq km, while the next smallest (Indian) is roughly 70 million sq km. It's also the shallowest ocean and centered around the North Pole region.

Nuclear power plants generate energy through fission - splitting heavy uranium atoms into lighter elements, releasing heat. Fusion (combining light atoms) occurs in stars and remains experimental for power generation on Earth.

Topography in anatomy refers to the detailed description and mapping of specific body parts or regions. This term is used in medical contexts to describe the precise location and characteristics of anatomical structures. Zootaxy is not a valid term, and Ornithology specifically studies birds.

Phonetics is the scientific study of speech sounds, including how they are produced (articulatory phonetics), transmitted (acoustic phonetics), and perceived (auditory phonetics). This definition precisely matches the question description. Mycology studies fungi, while Neuropathology studies nerve tissue diseases.

Ornithology is the branch of zoology that deals with the study of birds, including their behavior, physiology, classification, and ecology. This is the correct and established term for avian studies. Phonetics studies speech sounds, and Topography describes surface features.

Mycology is the branch of biology that studies fungi, including their genetic and biochemical properties, their taxonomy, and their use to humans as sources of medicine and food. It also encompasses the study of fungal diseases (mycoses). Genetics studies heredity, while Phonetics studies speech sounds.
