Which organelle is responsible for producing ATP through cellular respiration in eukaryotic cells?
Answer: Mitochondria
Mitochondria are the site of aerobic cellular respiration, producing the majority of ATP (adenosine triphosphate) used by the cell.
What type of chemical bond involves the sharing of electrons between atoms?
Answer: Covalent bond
Covalent bonds form when two atoms share one or more pairs of electrons, creating molecules such as H₂O and CO₂.
Which of Newton's laws states that for every action there is an equal and opposite reaction?
Answer: Third Law (Action-Reaction)
Newton's Third Law states that when object A exerts a force on object B, object B exerts an equal and opposite force on object A simultaneously.
What is the process by which water vapor cools and transforms into liquid water droplets, forming clouds?
Answer: Condensation
Condensation is the phase change from gas (water vapor) to liquid. In the atmosphere, water vapor condenses around dust particles at the dew point to form cloud droplets.
What is the atomic number of an element?
Answer: The number of protons in the nucleus
The atomic number equals the number of protons in an atom's nucleus. It uniquely identifies an element — carbon always has 6 protons, oxygen always has 8.
Which type of rock forms from the cooling and solidification of magma or lava?
Answer: Igneous
Igneous rocks form from the cooling of magma (underground) or lava (at the surface). Examples include granite (intrusive) and basalt (extrusive).
