Displacement is a vector quantity because it has both magnitude and direction. It describes the change in position of an object, unlike scalar quantities, which only have magnitude.Ice is the solid state of water, where molecules are tightly packed and vibrate in fixed positions, giving it a definite shape and volume.Red blood cells contain hemoglobin, which binds oxygen in the lungs and delivers it to body tissues for cellular respiration.Displacement is the shortest distance between the initial and final positions. In a full circle, the starting and ending points are the same, so displacement is zero.Speed is a scalar quantity because it only measures magnitude (how fast an object moves) without considering direction, unlike velocity, which is a vector.Displacement can be zero when an object returns to its starting point, as the net change in position is zero, regardless of the distance traveled.Newton’s third law states that for every action force, there is an equal and opposite reaction force, like a rocket pushing gas downward to move upward.Carbon dioxide traps heat in the Earth’s atmosphere, contributing significantly to the greenhouse effect, which warms the planet.Plasma is a state of matter with ionized, energetic particles (electrons and ions) that move freely, found in stars and lightning.The endoplasmic reticulum (ER), particularly the smooth ER, aids in detoxification by processing toxins in cells, especially in the liver.Ribosomes are cell structures that synthesize proteins by translating genetic instructions from mRNA, essential for cell functions.The Golgi apparatus packages and distributes proteins and lipids but does not directly participate in cell division, which involves structures like the nucleus.Noble gases (e.g., Neon, Argon, Krypton) are inert due to their full electron shells. Chlorine is a reactive halogen, not a noble gas.Ductility is the ability to be drawn into thin wires. Gold is the most ductile metal, capable of being stretched into extremely thin wires.The SI unit of electric current is the Ampere, measuring the flow of electric charge per unit time.Fluorine is the most reactive non-metal due to its high electronegativity, eagerly forming bonds with other elements.Water is a compound with the chemical formula H₂O, consisting of two hydrogen atoms bonded to one oxygen atom.Mitochondria produce ATP, the cell’s energy currency, through cellular respiration, earning them the title “powerhouse of the cell.”The Sun provides the primary energy for Earth’s climate system, driving weather patterns and heating the atmosphere.A stretched rubber band stores elastic potential energy, which is released when it snaps back to its original shape.At standard atmospheric pressure, water boils at 100°C, transitioning from liquid to gas.Mercury is the closest planet to the Sun, orbiting at an average distance of about 58 million kilometers.Nitrogen makes up about 78% of Earth’s atmosphere, far more than oxygen (21%) or other gases.Leaves contain chlorophyll, which captures sunlight to convert carbon dioxide and water into glucose during photosynthesis.The Newton is the SI unit of force, defined as the force required to accelerate a 1 kg mass by 1 m/s².Solar energy is renewable because it comes from the Sun, which is an abundant and sustainable resource.Transpiration is the evaporation of water from plant leaves, helping regulate water and nutrient movement.Copper is a metal and an excellent conductor of electricity due to its free electrons, unlike insulators like rubber or wood.The atomic number of carbon is 6, indicating it has 6 protons in its nucleus.Igneous rocks form when molten magma cools and solidifies, either below or on the Earth’s surface.Pure water has a neutral pH of 7, balancing hydrogen and hydroxide ions.The nucleus houses DNA, the genetic material that controls cell activities and inheritance.Table salt is sodium chloride, with the chemical formula NaCl, composed of sodium and chlorine ions.Dolphins are mammals, characterized by warm-bloodedness, live birth, and nursing their young with milk.Carbohydrates are the body’s primary energy source, broken down into glucose for cellular energy.Melting ice is a physical change because it alters the state of water without changing its chemical composition.The Joule is the SI unit of energy, measuring work done or energy transferred.Methane is a potent greenhouse gas, trapping heat in the atmosphere and contributing to global warming.The cell membrane controls the movement of substances in and out of the cell, maintaining homeostasis.The meter is the SI unit of length, used to measure distance or size.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
