Heart rate can fluctuate due to various factors including physical activity increasing demand for oxygen, health issues signaling stress on the body, or medications altering cardiovascular function.Combustion is a chemical reaction between substances, usually including oxygen and accompanied by the generation of heat and light in the form of flame.Dams are primarily constructed for purposes like generating hydroelectric power, irrigating farmland, and preventing floods by controlling water flow, but they are not typically designed for conserving land areas.Red blood cells contain hemoglobin, a protein that binds to oxygen in the lungs and releases it to tissues throughout the body, essential for cellular respiration and energy production.Genetics is the branch of biology that examines how traits and characteristics are passed from parents to offspring through genes, involving the study of DNA and inheritance patterns.The hydrologic cycle, also known as the water cycle, describes the continuous movement of water on, above, and below the Earth's surface through processes like evaporation, condensation, and precipitation.A fire blanket is a safety device made of fire-resistant material used to smother small fires by cutting off the oxygen supply, making it effective for contained blazes like those in kitchens.The small intestine is where the majority of chemical digestion and nutrient absorption occurs, with enzymes breaking down food into usable forms for the body.Photosynthesis is the biochemical process in which plants capture light energy to synthesize glucose from carbon dioxide and water, releasing oxygen as a byproduct.Fossils are the mineralized or otherwise preserved traces of animals, plants, or other organisms from past geological ages, providing evidence of evolutionary history.An invasive species is one that is introduced to a new habitat, often by human activity, where it can outcompete native species and disrupt the local ecosystem balance.The central nervous system comprises the brain and spinal cord, serving as the main control center for processing information and coordinating body functions.The outer core is a fluid layer of molten iron and nickel that generates Earth's magnetic field through convective currents, situated between the mantle and the solid inner core.A herbivore is an organism that primarily consumes plants as its source of energy and nutrients, such as rabbits or cows, allowing it to thrive in ecosystems rich in vegetation without relying on animal prey.The pancreas secretes enzymes that aid in breaking down carbohydrates, proteins, and fats in the small intestine, while also producing hormones like insulin to regulate blood sugar levels.Deserts receive minimal precipitation, leading to sparse vegetation and adaptations in organisms for water conservation, with hot days and cold nights due to lack of moisture.The cell is the smallest structural and functional unit of all living organisms, capable of performing essential life processes like metabolism, growth, and reproduction.Gravity is the attractive force between masses that pulls planets toward the sun, balancing with their orbital velocity to maintain stable paths in space.Chlorophyll is a green pigment in plant cells that absorbs light energy, primarily in the blue and red wavelengths, to drive the process of photosynthesis.Igneous rocks form when magma or lava cools and crystallizes, either beneath the Earth's surface (intrusive) or on the surface (extrusive), examples including granite and basalt.The kidneys act as filters, removing excess water, salts, and metabolic wastes from the blood to form urine, maintaining the body's fluid and electrolyte balance.Tides result from the gravitational forces exerted by the moon and, to a lesser extent, the sun, causing periodic rises and falls in sea levels.A volcano island forms when volcanic activity builds up landmass from the ocean floor until it emerges above the water surface, creating islands like Hawaii through repeated eruptions and lava accumulation.Chemical energy is stored in the bonds of molecules within food, which is released during digestion and cellular respiration to power bodily functions.Erosion is the process where wind, water, ice, or gravity transport and break down rocks and soil, reshaping landscapes over time.The cerebellum, located at the back of the brain, processes sensory information to fine-tune motor movements, ensuring smooth balance and coordination.Nitrogen comprises about 78% of Earth's atmosphere, playing a key role in the nitrogen cycle and serving as an inert gas that dilutes oxygen.Mitosis is the process by which a single cell divides into two identical daughter cells, essential for tissue growth, development, and replacing damaged cells.Tropical rainforests support an immense variety of species due to stable warm temperatures, high rainfall, and abundant resources, fostering complex food webs.The pH scale measures the concentration of hydrogen ions in a solution, ranging from 0 (highly acidic) to 14 (highly alkaline), with 7 being neutral.Mars earns its nickname from the iron oxide (rust) on its surface, giving it a reddish appearance, and it is the fourth planet from the sun.Symbiosis refers to interactions where organisms live together, which can be mutualistic (both benefit), commensal (one benefits, other unaffected), or parasitic (one benefits at other's expense).A seismograph detects and records the vibrations caused by seismic waves during an earthquake, helping to determine its magnitude and location.Plant roots anchor the plant in soil while taking up water and essential minerals through root hairs, transporting them to other parts via the vascular system.Sound waves are mechanical waves that propagate through the vibration of particles in a medium like air, water, or solids, unlike electromagnetic waves.Biodiversity encompasses the diversity of species, genetic variations, and ecosystems, which contributes to ecological stability and resilience against changes.The liver synthesizes bile, a digestive fluid that emulsifies fats in the small intestine, aiding in their breakdown and absorption.Earth's axial tilt of about 23.5 degrees causes varying sunlight exposure throughout the year, leading to seasonal changes in temperature and daylight.Calcium is a mineral that provides strength and structure to bones and teeth, and it also plays roles in muscle contraction and nerve signaling.An ecosystem includes all biotic (living) and abiotic (non-living) components interacting in a specific area, such as energy flow and nutrient cycling in a forest or pond.You scored 0 out of 40You scored 1 out of 40You scored 2 out of 40You
