Einstein's Special Theory of Relativity introduced which revolutionary concept?
Answer: The speed of light is constant and time passes differently for observers in different frames of reference
Special Relativity established that the speed of light is constant for all observers and that time dilation and length contraction occur at relativistic speeds.
The process of cellular respiration in biology serves which primary function?
Answer: Converting glucose into ATP (usable energy) through chemical reactions
Cellular respiration is the metabolic process that breaks down glucose to produce ATP, the primary energy currency of cells.
Which law of thermodynamics states that energy cannot be created or destroyed, only converted from one form to another?
Answer: The First Law of Thermodynamics
The First Law of Thermodynamics, also called the law of conservation of energy, states that total energy in a closed system remains constant.
In genetics, which term describes a trait that appears in offspring only when both copies of a gene carry that version?
Answer: Recessive
A recessive trait is only expressed when an organism inherits two copies of the recessive allele, one from each parent.
The water cycle (hydrological cycle) describes which continuous process on Earth?
Answer: The continuous movement of water through evaporation, condensation, precipitation, and collection
The water cycle describes how water continuously moves between the atmosphere, land surface, and subsurface through evaporation, condensation, and precipitation.
Which subatomic particles are found in the nucleus of an atom?
Answer: Protons and neutrons
The atomic nucleus contains positively charged protons and electrically neutral neutrons, while electrons orbit the nucleus in energy shells.
