Yes, movement can help differentiate living from non-living things. Living organisms move on their own in response to stimuli, while non-living objects require external forces for movement, lacking the ability to initiate motion independently.
Yes, a car is non-living because it does not grow, reproduce, or respond to stimuli. Unlike living organisms, it lacks metabolic processes and consciousness, functioning solely based on mechanical components and human operation.
I classify a car as non-living based on its inability to grow, reproduce, or respond to stimuli. It lacks metabolic processes, consciousness, and adaptation, relying solely on mechanical parts and external human operation.
I can grow, reproduce, respond to my environment, and adapt to changes. Unlike a car, I have metabolic processes, experience emotions, and possess consciousness, making me a living being with complex biological functions.
Living things grow, reproduce, respond to stimuli, use energy, and have complex cellular structures. In contrast, non-living things do not exhibit these characteristics, lacking processes like metabolism, adaptation, and self-repair that define life.
The image illustrates the process of evaporation followed by condensation. The steam from boiling water rises and, when cooled, it condenses into liquid form. This method is used in separation techniques like distillation for purifying water.
Yes, you can obtain both salt and water by using evaporation. Heating the saltwater solution allows the water to evaporate, leaving the salt behind as a solid, which can then be collected.
To obtain clear water, using two to three layers of fine cloth is typically sufficient. This allows larger particles and impurities to be trapped while enabling cleaner water to pass through effectively.
Chapter 9 explains various methods of separation, including filtration, handpicking, winnowing, and evaporation. These techniques help us purify and sort materials in everyday life, emphasizing their importance in cooking, agriculture, and science.
