Which organ in the human body produces bile to aid in digestion?

Which gas is released by plants during photosynthesis?
Answer: Oxygen
Plants release oxygen as a byproduct of photosynthesis when they convert carbon dioxide and water into glucose using sunlight.
What is the function of the stomata in plant leaves?
Answer: Exchange of gases and transpiration
Stomata are tiny pores on plant leaves that allow gas exchange (CO₂ in, O₂ out) and regulate water loss through transpiration.
A student observes that iron rusts faster near the seashore than inland. Which factor is most responsible?
Answer: Presence of salt in moist air
Salt (sodium chloride) in the moist coastal air acts as an electrolyte that accelerates the electrochemical process of rusting.
Which part of the human eye is responsible for controlling the amount of light entering it?
Answer: Iris
The iris is the colored part of the eye that controls the size of the pupil, thereby regulating how much light enters the eye.
What is the process by which water vapor in the atmosphere cools and changes into liquid water droplets?
Answer: Condensation
