Plants take in carbon dioxide and release oxygen as a byproduct of photosynthesis, providing the air we need to survive. This process happens in chloroplasts using sunlight energy.Venus takes 243 Earth days to rotate once but only 225 days to orbit the Sun, making its day longer than its year. Its thick atmosphere drives this slow spin.Mitochondria convert nutrients into ATP through cellular respiration, acting as the cell’s energy factories. They even have their own DNA inherited from your mom.The stomach secretes hydrochloric acid (pH 1-2) to break down food and kill bacteria. It’s strong enough to corrode some metals over time.Gravity pulls planets toward the Sun, balancing their forward motion to create stable orbits. Newton’s law describes this universal attraction.Neon gas emits a bright reddish-orange glow when electrified in tubes, creating iconic neon signs. Other noble gases produce different colors.White blood cells (leukocytes) detect and destroy pathogens through immune responses. They’re crucial for fighting infections.For every action, there’s an equal and opposite reaction—like the wall pushing back when you lean on it.Skin exposed to UVB rays synthesizes vitamin D, which helps absorb calcium for healthy bones. Deficiency causes rickets.Electrons orbit the nucleus in electron clouds at near-light speeds, determining chemical behavior. They’re negatively charged.Inhaling helium speeds up sound waves in your vocal tract, raising pitch to a squeaky level. It’s lighter than air.Kidneys filter waste and excess fluids from blood to form urine, regulating balance. They process about 180 liters daily.Igneous rocks (like granite or basalt) crystallize from cooling magma or lava. “Igneous” means born of fire.Ampere (amp) measures the flow rate of electric charge—one amp equals one coulomb per second.Photosynthesis converts light energy into glucose using CO₂ and water in chloroplasts. The equation is 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂.DNA (deoxyribonucleic acid) stores genetic instructions in a double-helix structure. It’s found in the nucleus.Light travels at approximately 299,792 km/s in a vacuum, the universal speed limit according to relativity.Adrenaline (epinephrine) triggers the fight-or-flight response, increasing heart rate and energy. It’s released by adrenal glands.The ozone layer in the stratosphere absorbs most ultraviolet radiation, protecting life from DNA damage.Humans exhale CO₂ from cellular respiration, which plants use for photosynthesis during the day.Galileo demonstrated that objects fall at the same rate regardless of mass (ignoring air resistance) in his Pisa experiments.Roots absorb water and minerals from soil while anchoring the plant. Root hairs increase surface area.Mercury’s high boiling point and expansion with heat made it ideal for thermometers before safer alternatives.Higher frequency sound waves produce higher pitch; frequency is measured in hertz (Hz).Marine ecosystems host diverse species from plankton to whales, regulating climate and oxygen.Covalent bonds form when atoms share electrons to achieve stability, like in H₂O molecules.The Hubble Space Telescope orbits above the atmosphere, capturing clear images of distant galaxies since 1990.Jupiter’s Great Red Spot is a massive anticyclonic storm larger than Earth, observed since the 1600s.A pH of 7 indicates neutrality; pure water has this value. Below 7 is acidic, above is basic.Ernest Rutherford’s gold foil experiment revealed the atomic nucleus, paving the way for nuclear physics.Elastic potential energy is stored in the compressed spring, released as kinetic energy when unwound.Lizards are ectothermic, absorbing heat from the environment to regulate temperature.Chlorophyll absorbs red and blue light for photosynthesis, reflecting green. It’s in chloroplasts.Cells are the basic structural and functional units of life, capable of metabolism and reproduction.Concave mirrors curve inward, focusing light to produce magnified images, like in makeup mirrors.Coal formed from compressed plant matter over millions of years and is burned to generate electricity.The pineal gland secretes melatonin to regulate sleep-wake cycles based on light exposure.Neutrons are neutral particles in the nucleus, contributing to atomic mass and stability.The Richter scale quantifies earthquake magnitude logarithmically; each step represents 10x more energy.Neutralization occurs when acid and base react to form water and ionic salt, balancing pH.You scored 0 out of 40You scored 1 out of 40You scored 2 out of 40You scored 3 out of 40You scored 4 out of 40You scored 5 out of 40You scored 6 out of 40You scored 7 out of 40You scored 8 out of 40You scored 9 out of 40You scored 10 out of 40You scored 11 out of 40You scored 12 out of 40You scored 13 out of 40You scored 14 out of 40You scored 15 out of 40You scored 16 out of 40You scored 17 out of 40You scored 18 out of 40You scored 19 out of 40You scored 20 out of 40You scored 21 out of 40You scored 22 out of 40You scored 23 out of 40You scored 24 out of 40You scored 25 out of 40You scored 26 out of 40You scored 27 out of 40You scored 28 out of 40You scored 29 out of 40You scored 30 out of 40You scored 31 out of 40You scored 32 out of 40You scored 33 out of 40You scored 34 out of 40You scored 35 out of 40You scored 36 out of 40You scored 37 out of 40You scored 38 out of 40You scored 39 out of 40You scored 40 out of 40
