What is the process of photosynthesis? Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. It involves the green pigment chlorophyll and generates oxygen as a byproduct.
How do we classify materials as conductors or insulators? Materials are classified as conductors or insulators based on their ability to conduct electricity. Conductors allow electric charge to flow through them easily, whereas insulators do not.
What is the role of the ozone layer for living organisms? The ozone layer protects Earth’s living organisms by absorbing and scattering the majority of the sun’s harmful ultraviolet radiation.
Describe the water cycle briefly. The water cycle describes the continuous movement of water on, above, and below the surface of the Earth, involving processes such as evaporation, condensation, precipitation, and runoff.
What causes the tides in the oceans? Tides are caused by the gravitational forces exerted by the moon and the sun and the rotation of the Earth.
Explain how fossils are formed. Fossils are formed when plants or animals are buried in sedimentary rock, preserving their shapes as the organic matter decays and is replaced with minerals over time.
What are renewable energy sources? Give two examples. Renewable energy sources are those that can be replenished naturally over short periods. Examples include solar energy and wind energy.
How does the human eye function to see objects? The human eye functions by focusing light through the cornea and lens to form an image on the retina, which sends signals to the brain via the optic nerve.
What is ecological succession? Ecological succession is the process by which the structure of a biological community evolves over time, involving species that gradually replace one another.
Describe Newton’s third law of motion. Newton’s third law states that for every action, there is an equal and opposite reaction. This means that forces always occur in pairs that are equal in magnitude and opposite in direction.
Why is genetic diversity important in populations? Genetic diversity increases the chances of survival and adaptation of a population by providing a broader range of traits for natural selection.
How does pollution affect ecosystems? Pollution can lead to harmful effects on individual species and whole ecosystems, reducing biodiversity and disrupting normal life processes.
What is the principle behind hydraulic systems? Hydraulic systems operate based on Pascal’s principle, where pressure applied at any point in a confined fluid is transmitted undiminished throughout the fluid.
How do vaccinations work? Vaccinations work by introducing a harmless piece of a virus or bacterium into the body, prompting the immune system to respond and build immunity without causing the disease.
What role do decomposers play in an ecosystem? Decomposers break down dead organisms and waste materials, recycling essential nutrients back into the ecosystem.
Explain the greenhouse effect. The greenhouse effect is the warming of the Earth’s surface and atmosphere caused by the presence of greenhouse gases which trap heat from the sun.
What are the major parts of the brain and their functions? The major parts of the brain include the cerebrum (responsible for higher cognitive functions), the cerebellum (coordinates movement), and the brainstem (controls basic life functions).
Why do we need to conserve biodiversity? Conserving biodiversity ensures the sustainability of our natural resources and maintains ecological balance.
How do earthquakes occur? Earthquakes occur due to the sudden release of energy in the Earth’s crust that creates seismic waves, often caused by tectonic plates shifting.
What is the difference between a virus and a bacterium? Viruses are small infectious agents that need a host cell to replicate, while bacteria are single-celled organisms that can live independently and perform all necessary life processes.
