Helium was first detected in the sun’s spectrum during a solar eclipse in 1868 before it was found on Earth. It’s the second most abundant element after hydrogen, making up a significant part of stars.Chloroplasts contain chlorophyll, a pigment that absorbs sunlight to drive photosynthesis. This process converts light energy into chemical energy stored in glucose.Gravity is the force that pulls planets toward the sun, keeping them in stable orbits. Without it, planets would drift away in straight lines.Phosphorus forms part of the sugar-phosphate backbone of DNA, linking nucleotides together. This structure is crucial for DNA’s stability and function.The Richter Scale measures the magnitude of earthquakes based on seismic wave amplitude. It’s a logarithmic scale, so each whole number represents a tenfold increase in energy.Electrons are negatively charged particles that orbit the nucleus of an atom. They play a key role in chemical bonding and electricity.Hydrogen bonds form between the slightly positive hydrogen atoms and slightly negative oxygen atoms of neighboring water molecules. These bonds give water its unique properties, like high surface tension.Mitochondria produce ATP, the cell’s main energy currency, through cellular respiration. They’re essential for powering cellular activities.Solar radiation from the sun drives Earth’s climate by heating the atmosphere, oceans, and land. It powers weather patterns and the water cycle.Venus’s atmosphere is about 96% carbon dioxide, creating a intense greenhouse effect that makes it the hottest planet. This thick gas layer traps heat effectively.Herbivores, like cows and deer, exclusively eat plant material for their nutrition. Their digestive systems are adapted to break down tough plant fibers.The ampere (amp) measures the flow of electric charge, or current, in a circuit. It’s defined as one coulomb of charge per second.Sunlight triggers the skin to produce vitamin D, which helps the body absorb calcium for strong bones. It’s often called the “sunshine vitamin.”Proxima Centauri, part of the Alpha Centauri system, is 4.24 light-years away, making it the closest known star to Earth after the sun. It’s a faint red dwarf.Igneous rocks, like granite or basalt, form when molten magma or lava cools and solidifies. Their texture depends on the cooling rate.The cerebellum, located at the back of the brain, coordinates voluntary movements like balance and posture. It fine-tunes motor skills for smooth actions.Neon, a noble gas, emits a bright red-orange glow when electrified, making it ideal for neon signs. It was first identified in the sun’s spectrum.Hurricanes draw energy from warm ocean water, which evaporates and fuels their intense winds and storms. Water temperatures above 26.5°C are ideal.ATP (adenosine triphosphate) is the cell’s primary energy carrier, releasing energy when its bonds are broken. It powers most cellular processes.Perihelion is when a planet is closest to the sun in its elliptical orbit, resulting in faster orbital speed. For Earth, this occurs around early January.Gamma rays have the shortest wavelength and highest energy in the electromagnetic spectrum. They’re produced by radioactive decay and cosmic events.The pancreas produces insulin, a hormone that regulates blood sugar levels. It’s released by beta cells in the islets of Langerhans.Evaporation is the process where liquid water turns into vapor due to heat, often from the sun. It’s a key part of the water cycle.Oxygen makes up about 46% of Earth’s crust by weight, primarily in compounds like silicates. It’s found in rocks, minerals, and water.A stretched rubber band stores elastic potential energy due to its deformation. When released, this energy converts to kinetic energy, causing it to snap back.Ants have the largest brain-to-body size ratio among animals, with their brains making up a significant portion of their tiny bodies. This supports their complex social behaviors.Nitrogen makes up about 78% of Earth’s atmosphere by volume. It’s a relatively inert gas, essential for life in compounds like proteins.Exothermic reactions release heat into the surroundings, like combustion or neutralization. This makes the surroundings feel warmer.Mars appears red due to iron oxide (rust) on its surface. This distinctive color is visible even from Earth.Mitosis is the process where a eukaryotic cell divides its nucleus to produce two identical daughter cells. It’s essential for growth and repair.Earth’s magnetic field is generated by the movement of molten iron in its outer core, a process called the geodynamo. This creates a protective magnetic shield.Cumulonimbus clouds are tall, dense clouds that produce thunderstorms, heavy rain, and lightning. They often have an anvil-shaped top.Hemoglobin, found in red blood cells, binds oxygen in the lungs and transports it to tissues. Its iron content gives blood its red color.Free fall describes an object falling under gravity alone, without air resistance, accelerating at 9.8 m/s². All objects fall at the same rate in a vacuum.Nitrogen, when excited by charged particles from the sun, emits green light in auroras. This creates the vibrant displays in polar skies.A catalyst lowers the activation energy of a chemical reaction, speeding it up without being used up. Enzymes are common biological catalysts.Saturn has the most known moons, with over 140, including Titan, its largest. Many are still being discovered or confirmed.The cuticle is a waxy, waterproof layer on plant leaves and stems that reduces water loss. It helps plants survive dry conditions.The watt measures power, or the rate of energy transfer, defined as one joule per second. It’s used for things like light bulbs and engines.Arteries carry oxygenated blood away from the heart to the body’s tissues, except for the pulmonary artery, which carries deoxygenated blood to the lungs. They have thick, elastic walls to handle high pressure.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
