The skeleton provides structure and support to the body, protects internal organs, stores minerals, and produces blood cells in the bone marrow.

29. What is the process of transpiration in plants?
Transpiration is the process by which plants lose water vapor through small openings in their leaves. This helps in the movement of water and nutrients from the roots.

30. What is the difference between reflection and refraction of light?
Reflection occurs when light bounces off a surface, while refraction happens when light bends as it passes from one medium to another.

31. What is the importance of water for living organisms?
Water is essential for life as it helps in digestion, temperature regulation, transporting nutrients, and removing waste from the body.

32. How does the process of pollination occur?
Pollination occurs when pollen from the male part of a flower is transferred to the female part, leading to fertilization and seed production.

Decomposers break down dead organic matter into simpler substances, returning nutrients to the soil and maintaining ecological balance.

36. What is a chemical reaction?
A chemical reaction occurs when substances combine or break apart to form new substances with different properties.

37. How do plants obtain water?
Plants absorb water from the soil through their roots. This water travels up to the leaves through the plant's vascular system.

38. What is the function of the immune system?
The immune system defends the body against infections by recognizing and fighting off harmful pathogens like bacteria, viruses, and fungi.

In an open circuit, the path is incomplete, preventing current from flowing, while in a closed circuit, the path is complete, allowing the current to flow.

40. How do we see objects?
We see objects because light reflects off them and enters our eyes, where it is processed by the brain to form images.

41. What is an eclipse?
An eclipse occurs when one celestial body passes in front of another, blocking its light. A solar eclipse happens when the moon blocks the sun, and a lunar eclipse occurs when the Earth blocks the moon's light.

42. How do plants respond to light?
Plants respond to light by growing towards it, a phenomenon called phototropism. This helps them maximize photosynthesis.
