ExplanationThe atomic number represents the number of protons in an atom; Carbon has 6 protons in its nucleus.
Proton
Electron
Neutron
Photon
ExplanationNeutrons are neutral particles located in the atomic nucleus.
Respiration
Photosynthesis
Fermentation
Digestion
ExplanationPhotosynthesis is the chemical process plants use to convert light energy into chemical energy.
Joule
Watt
Newton
Pascal
ExplanationThe Newton (N) is the SI unit for force, defined as 1 kg·m/s^2.
Nucleus
Mitochondrion
Ribosome
Golgi apparatus
ExplanationMitochondria produce adenosine triphosphate (ATP), the main energy molecule of the cell.
Loss of electrons
Gain of electrons
Loss of oxygen
Gain of protons
ExplanationReduction is defined as the gain of electrons during a chemical reaction.
Newton's First Law
Newton's Second Law
Newton's Third Law
Kepler's Law
ExplanationNewton's Third Law defines the nature of paired forces acting between objects.
Oxygen
Nitrogen
Carbon
Hydrogen
ExplanationCarbon's ability to form stable bonds with many elements makes it the backbone of organic chemistry and life.
Identical clones are produced
The cell count remains the same
Chromosome number is reduced by half
The nucleus disappears
ExplanationMeiosis is a special type of cell division that results in four daughter cells with half the chromosomes of the parent.
Above 7
Exactly 7
Below 7
Above 14
ExplanationA pH level below 7 indicates an acidic solution, while 7 is neutral and above 7 is basic.
It decreases
It stays constant
It increases due to gravity
It stops
ExplanationGravity causes a constant acceleration (approx 9.8 m/s²), which increases the downward velocity over time.
Oxygen
Carbon dioxide
Nitrogen
Helium
ExplanationPhotosynthesis uses carbon dioxide, water, and light energy to produce glucose.
Gd
Au
Ag
Fe
ExplanationAu comes from the Latin word 'aurum'.
The origin of life on Earth
The evolution of species
The origin and expansion of the universe
The tectonic shifts of continents
ExplanationThe Big Bang theory describes the universe beginning from a hot, dense singularity and expanding.
Liver
Kidneys
Stomach
Heart
ExplanationThe kidneys filter waste products and excess water from the blood to create urine.
Transfer of electrons between atoms
Sharing of electron pairs between atoms
Attraction between oppositely charged ions
Weak hydrogen interactions
ExplanationCovalent bonding involves the sharing of electron pairs to stabilize atoms.
Solar
Wind
Coal
Hydroelectric
ExplanationFossil fuels like coal take millions of years to form and are finite in supply.
Evaporation
Condensation
Sublimation
Freezing
ExplanationCondensation is the process where gas turns into liquid, typically when cooling.
Kinetic
Thermal
Elastic potential
Chemical
ExplanationEnergy stored due to deformation of an elastic object is potential energy.
Dendrite
Axon
Synapse
Nucleus
ExplanationThe axon is the long extension of a nerve cell that transmits electrical impulses.
Positive
Negative
Neutral
Variable
ExplanationNeutrons have no electric charge, unlike protons (positive) and electrons (negative).
To generate energy
To act as a structural barrier
To store genetic information
To break down waste
ExplanationDNA carries the instructions for the development, functioning, and reproduction of organisms.
Faraday's Law
Ohm's Law
Hooke's Law
Boyle's Law
ExplanationOhm's law states V=IR, where V is voltage, I is current, and R is resistance.
Number of neutrons
Number of protons
Mass of the atom
Number of shells
ExplanationThe atomic number is defined strictly by the count of protons in an atom's nucleus.
Carbon dioxide
Nitrogen
Oxygen
Argon
ExplanationWhile we need oxygen, Nitrogen makes up approximately 78% of the Earth's atmosphere.
Increase the reaction rate
Decrease the temperature needed
Change the final product
Absorb heat
ExplanationA catalyst lowers the activation energy required for a reaction to proceed, thus speeding it up.
Frequently Asked Questions
Are these Natural Sciences (Physics, Chemistry, Biology) MCQs free?
Yes. Every Natural Sciences (Physics, Chemistry, Biology) MCQ on this page is free to practice, including the correct answer and explanation.
Do these include past-paper questions?
Yes — questions sourced from past papers are clearly marked with a "Past Paper" badge, alongside fresh practice questions.
Which exams do these Natural Sciences (Physics, Chemistry, Biology) MCQs help with?
They are aimed at Ministry of Education of the People's Republic of China and related Pakistani competitive exams that test Natural Sciences (Physics, Chemistry, Biology).
How should I practice subject-wise MCQs?
Attempt each question first, then reveal the answer and read the explanation. Short, focused sessions on one subject work better than long unstructured reading.
