FAQs (Frequently Asked Questions)
What are the characteristics of living organisms?
Living organisms share several key characteristics, including cellular organization, reproduction, growth and development, response to stimuli, energy utilization (metabolism), and the ability to adapt to their environment.
How did life originate on Earth?
