Camouflage helps animals blend into their surroundings, making it harder for predators to spot them. Food provides energy, migration is seasonal movement, and fire is not a natural defense mechanism for animals.Hibernation is when animals slow their metabolism and become inactive during winter to conserve energy. Consumption and eating are related to food intake, and extinction means a species no longer exists.Friction is the force that resists motion when two surfaces rub against each other. Conduction transfers heat, radiation involves energy waves, and magnetism attracts certain materials.Migration is when animals move from one place to another, often seasonally, for food or breeding. Aging is growing older, hibernation is winter inactivity, and changing form is metamorphosis.Solar energy comes from the sun’s rays, which can be harnessed for power. Windmills use wind, electric cars run on electricity, and batteries store energy.An endangered species is at high risk of extinction. Threatened species are at risk but less severe, exotic species are non-native, and common species are widespread.Density measures how much mass is packed into a given volume. Color, height, and length are unrelated to density.A habitat is the natural environment where an organism lives. Ocean, tree, and grass are specific places, not the general term.A microscope magnifies tiny objects like cells. Telescopes view distant objects, stethoscopes listen to sounds, and periscopes redirect light.A carnivore eats mainly meat. Herbivores eat plants, omnivores eat both, and predators hunt other animals but may not only eat meat.Lungs take in oxygen, which the heart pumps through the body. The brain controls functions, the stomach digests food, and kidneys filter waste.Gravity is the force that attracts objects toward each other, like Earth pulling objects downward. Weight is a result of gravity, volume measures space, and electricity is unrelated.Microscopic structures require a microscope to see. Macroscopic objects are visible to the naked eye, and heteroscopic/endoscopic are not standard terms.Conservation means protecting and preserving resources. Rotation is turning, pollution harms the environment, and agriculture is farming.Reptiles, like snakes and lizards, lay eggs, breathe air, and have scales. Mammals give live birth, ducks are birds, and insects have exoskeletons.Germs are tiny organisms, like bacteria or viruses, that can cause disease. Insects and plants are larger, and diseases are caused by germs.Vaporization is when a liquid turns into a gas, like water evaporating. Freezing turns liquid to solid, chilling cools, and melting turns solid to liquid.Food provides energy for the body to function. Dark matter is cosmic, sunlight is external, and time is unrelated.Charles Darwin developed the theory of evolution by natural selection. Circumnavigation is travel, climate change is modern, and gravity is Newton’s discovery.The sun provides the energy that drives Earth’s climate through heat and light. The moon affects tides, volcanoes release heat, and oceans store energy.Omnivores eat both plants and animals, like humans. Herbivores eat plants, carnivores eat meat, and decomposers break down dead matter.A thermometer measures temperature. Rulers measure length, scales measure weight, and compasses show direction.Photosynthesis is how plants use sunlight, water, and carbon dioxide to make food. Respiration uses oxygen, digestion breaks down food, and fermentation produces energy without oxygen.The lithosphere is Earth’s solid crust. The atmosphere is air, the hydrosphere is water, and the biosphere includes living things.Plants take in carbon dioxide during photosynthesis to produce food and release oxygen. Oxygen is released, nitrogen is abundant but not used, and hydrogen is in water.A force is a push or pull that can cause motion. Energy enables work, motion is movement, and speed measures how fast something moves.The nucleus is the center of an atom, containing protons and neutrons. Electrons orbit the nucleus, protons carry positive charge, and neutrons are neutral.Food stores chemical energy, which the body uses for growth and activity. Thermal is heat, kinetic is motion, and electrical is current.The embryo is the young plant inside a seed that grows when conditions are right. Roots, stems, and leaves develop from it.Metamorphosis is the transformation of an insect, like a caterpillar into a butterfly. Evolution is species change, migration is movement, and hibernation is inactivity.The crust is Earth’s thin, outermost layer. The core is the center, the mantle is below the crust, and magma is molten rock.Vertebrates have a backbone, like mammals and birds. Invertebrates lack a backbone, and reptiles/amphibians are specific vertebrate groups.The sun is Earth’s primary light source, driving day and night. The moon reflects sunlight, stars are distant, and fire is artificial.Precipitation is water falling as rain, snow, or hail. Evaporation turns liquid to gas, condensation forms clouds, and sublimation is solid to gas.Cells are the basic building blocks of life, making up all living organisms. Atoms form molecules, which form cells, and tissues are groups of cells.The atmosphere is the layer of gases around Earth. The hydrosphere is water, the lithosphere is solid ground, and the biosphere is living things.Melting is when a solid, like ice, turns into a liquid. Freezing is the reverse, evaporation turns liquid to gas, and condensation turns gas to liquid.Amphibians, like frogs, live in water and on land. Reptiles prefer land, mammals vary, and birds primarily live on land or in air.The water cycle describes how water moves through evaporation, condensation, and precipitation. Other cycles involve rocks, carbon, or nitrogen.A balance measures an object’s mass by comparing it to known weights. Rulers measure length, thermometers measure temperature, and barometers measure air 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
