Scientific Questions

Earth's shape is due to gravitational forces that pull matter into a spherical form.
Stars remain in the sky and maintain positions due to gravitational interactions and the dynamics of celestial objects.
Giraffe's food takes considerable time to digest, typically around 24-48 hours, to travel through their digestive system.
Only mammals possess hair as a characteristic feature, aiding in insulation, sensory perception, and protection.
Humans perceive color through specialized cells in the eyes called cones, which are sensitive to different wavelengths of light.
Humans cannot fly due to anatomical limitations such as bone structure, muscle mass, and lack of wings needed for flight.
