Which planet is known as the Red Planet?
Jupiter
Earth

Mars appears red due to iron oxide on its surface. This distinctive hue has earned it the nickname "Red Planet."
What is the boiling point of water at sea level in Celsius?
90°C
0°C
100°C
212°C
At standard atmospheric pressure (sea level), water boils at 100°C. This is a fundamental reference point for temperature scales.
What is the largest organ in the human body?
Heart
Liver
Skin
Brain
The skin is the largest organ by surface area and weight. It protects internal tissues and regulates temperature.
What is the chemical symbol for water?
CO2
H2O
H2
O2
Water is composed of two hydrogen atoms bonded to one oxygen atom, giving the chemical formula H2O. This is a basic chemistry fact.
Which gas do plants primarily absorb from the atmosphere during photosynthesis?
Oxygen
Nitrogen
Carbon dioxide
Hydrogen
During photosynthesis, plants take in carbon dioxide (CO2) and convert it into glucose and oxygen. This process is fundamental to plant biology.
Newton's First Law of Motion is also known as the law of what?
Action and reaction
Gravity
Inertia
Acceleration
Newton's First Law states that an object will remain at rest or in uniform motion unless acted upon by a net external force. This principle is commonly referred to as the law of inertia.
In which organelle does cellular respiration primarily occur?
Chloroplast
Nucleus
Ribosome
Mitochondria
Mitochondria are known as the powerhouse of the cell because they generate ATP via cellular respiration. This makes them the main site for energy production.
Who formulated the law of universal gravitation?
Albert Einstein
Johannes Kepler
Isaac Newton
Galileo Galilei
Isaac Newton published the law of universal gravitation in his work "Principia Mathematica." It describes the gravitational attraction between masses.
The formula for calculating density is mass divided by what?
Weight
Volume
Length
Area
Density is defined as mass (m) divided by volume (V). This relationship is fundamental in understanding material properties.
What is the pH value of a neutral solution at 25°C?
14
7
0
1
At 25°C, pure water has a pH of 7, which is considered neutral on the pH scale. Values below 7 are acidic and above 7 are basic.
Which element has the atomic number 6?
Nitrogen
Oxygen
Carbon
Helium
The atomic number indicates the number of protons in an element's nucleus. Carbon has 6 protons, so its atomic number is 6.
How many chromosomes are present in a typical human gamete?
46
23
22
44
Human gametes (sperm and egg cells) are haploid and contain 23 chromosomes. When fertilization occurs, the diploid number of 46 is restored.
A car travels 150 km in 3 hours. What is its average speed in km/h?
50 km/h
45 km/h
150 km/h
75 km/h
Average speed is calculated by dividing total distance by total time. Here, 150 km ÷ 3 h equals 50 km/h.
Which instrument is used to measure atmospheric pressure?
Thermometer
Barometer
Hygrometer
Anemometer
A barometer measures atmospheric pressure by balancing the weight of mercury against atmospheric force. It is essential in weather forecasting.
What phenomenon causes the sky to appear blue?
Reflection
Refraction
Diffraction
Rayleigh scattering
Rayleigh scattering preferentially scatters shorter (blue) wavelengths of sunlight in the atmosphere. This is why the sky appears blue to our eyes.
According to Einstein's mass - energy equivalence, E equals what expression?
m×c^2
m×g
½mv^2
p×v
Einstein's famous equation E = mc^2 describes how mass (m) can be converted into energy (E) with c representing the speed of light. It underpins modern physics and nuclear energy applications.
In a Punnett square cross between two heterozygous organisms (Aa × Aa), what is the probability of an offspring being homozygous recessive?
0%
75%
25%
50%
A Punnett square of Aa × Aa yields one AA, two Aa, and one aa genotype. Thus, there is a 1 in 4 chance, or 25%, of an offspring being homozygous recessive (aa).
Which best describes entropy in thermodynamics?
Measure of heat capacity
Measure of pressure
Measure of disorder
Measure of energy
Entropy quantifies the degree of disorder or randomness in a system. It plays a central role in the second law of thermodynamics and predicts the direction of natural processes.
When analyzing a star's spectrum, a redshift indicates that the star is doing what?
Remaining stationary
Rotating rapidly
Moving towards the observer
Moving away from the observer
A redshift occurs when spectral lines shift toward longer wavelengths, indicating that an object is moving away due to the Doppler effect. Astronomers use this to measure cosmic expansion.
In statistical hypothesis testing, a p-value below 0.05 typically suggests what action?
Accept the null hypothesis
Reject the null hypothesis
Increase the sample size
Accept the alternative without evidence
A p-value below 0.05 indicates that the observed data is unlikely under the null hypothesis at a 5% significance level. Statistically, this leads to rejection of the null hypothesis in favor of the alternative.

  4. Apply scientific reasoning to practical scenarios
  5. Demonstrate mastery of core general knowledge trivia
  6. Interpret data to draw evidence-based conclusions

Cheat Sheet

  1. Master the Scientific Method - Science is a grand detective game where you observe clues, make wild guesses in the form of hypotheses, run experiments to test them, and draw conclusions like a pro sleuth. Embrace this logical toolkit to answer life's big "whys" and "hows" with style! Dive into the Scientific Method
  2. Grasp the Law of Conservation of Energy - Think of energy as a mischievous shape-shifter that can never be created or destroyed but loves to change costumes between heat, light, and motion. This magical rule underpins everything from rolling marbles to powering starships (well, almost!). Discover the Conservation of Energy
  3. Understand Evolution by Natural Selection - Picture nature as an epic reality show where only the fittest contestants (aka organisms) pass on their traits to the next generation. Over eons, this survival-of-the-coolest process crafts the dazzling diversity of life on Earth. Evolution by Natural Selection Explained
  4. Comprehend Cell Theory - Cells are the tiny building blocks that assemble into all living things, sort of like LEGO bricks forming everything from algae to zebras. Remember: every cell springs from another cell, so it's truly a family affair! Explore Cell Theory
  5. Learn the Laws of Motion - Newton's three laws turn everyday pushes and pulls into a universal anthem - objects stay still or move straight unless nudged, force equals mass times acceleration, and for every action there's an equal and opposite reaction. Ride these principles to ace everything from skateboarding tricks to rocket launches! Dive into Newton's Laws
  6. Explore the Periodic Table - Imagine a grand periodic party chart where each element has its own atomic badge number, electron outfit, and quirky chemical habits. This table helps you predict which elements will mingle well (or explode spectacularly!). Blast Off Into the Periodic Table
  7. Understand Plate Tectonics - Earth's crust is like a cracked eggshell floating on gooey magma, with giant plates drifting, colliding, and pulling apart to craft mountains, trenches, and epic earthquakes. It's geology's ultimate dance floor! Uncover Plate Tectonics
  8. Recognize the Second Law of Thermodynamics - In any energy handoff, disorder (entropy) always creeps in like an uninvited party guest who refuses to leave. This rule means your room will get messier and your hot coffee cooler - science's way of keeping life interesting! Get the Scoop on Entropy
  9. Study Mendelian Genetics - Dive into pea plants (yes, peas!) to see how traits like flower color follow clear-cut patterns via dominant and recessive genes. Gregor Mendel's pea plot is your ticket to understanding heredity's secret code. Peep Mendelian Genetics
  10. Understand Quantum Mechanics - Shrink down to the atomic dance floor where particles moonlight as waves, teleport through barriers, and follow rules stranger than fiction. Welcome to the micro-universe that powers lasers, LEDs, and maybe future teleporters! Quantum Quirkiness 101
