Explanations
1. Which of these reduces friction?
• A) Ball bearings
• B) Sandpaper
• C) Rough surfaces
• D) Adhesives
Answer: A) Ball bearings
Rationale: Ball bearings reduce friction by converting sliding friction
into rolling friction, which has a much lower coefficient of resistance.
This allows parts to move smoothly with less energy loss.
2. When a lobster grows a claw to replace one that was lost, the
process is called?
• A) Regeneration
• B) Reproduction
• C) Metamorphosis
• D) Mutation
,Answer: A) Regeneration
Rationale: Regeneration is the biological process by which organisms
regrow lost or damaged body parts. Lobsters, like many crustaceans,
can regrow claws through this process.
3. Astronomical body that revolves around a larger body:
• A) Planet
• B) Satellite
• C) Comet
• D) Asteroid
Answer: B) Satellite
Rationale: A satellite is any celestial body that orbits a larger body. This
includes natural satellites (moons) and artificial satellites. Planets orbit
stars, but the term "satellite" specifically describes a body revolving
around a larger body.
4. In chemistry, to be classified as an organic substance, a substance
must contain?
• A) Oxygen atoms
• B) Carbon atoms
• C) Hydrogen atoms
• D) Nitrogen atoms
, Answer: B) Carbon atoms
Rationale: Organic chemistry is defined as the study of carbon-
containing compounds. While many organic substances also contain
hydrogen, oxygen, and other elements, the presence of carbon atoms is
the defining characteristic.
5. Which element does not contain any neutrons?
• A) Hydrogen
• B) Helium
• C) Lithium
• D) Carbon
Answer: A) Hydrogen
Rationale: The most common isotope of hydrogen (protium) has one
proton and zero neutrons. Helium has 2 neutrons, lithium has 4, and
carbon has 6 neutrons in their most common isotopes.
6. The chemical formula of a compound describes the elements...
• A) Ratio of elements
• B) Types of bonds
• C) Physical state
• D) Reactivity
