Yes, birds show significant changes in their life cycle. They start as eggs, hatch into chicks, and undergo developmental stages like fledgling and juvenile before reaching adulthood. Each stage involves notable physical and behavioral changes.
Plant seeds in separate containers at different temperatures (e.g., 10°C, 20°C, 30°C). Monitor germination rates and growth. Compare results to determine if temperature affects the speed and success of seed germination.
A seed is considered living because it contains dormant embryonic plants that can grow under the right conditions. While it may not show activity in its dry state, it can germinate, grow, and develop into a new plant, indicating life.
Living creatures differ from non-living things in their ability to grow, reproduce, respond to stimuli, and maintain internal balance. Non-living things do not possess these abilities or biological functions.
Living creatures grow by increasing in size and complexity. This growth involves cellular multiplication and expansion, development of tissues and organs and overall maturation, driven by genetic instructions and environmental factors.
