• It is thinner in the center than at the edges.
• This lens disperses light rays, allowing them to focus correctly on the retina.

Explanation

• The Earth is tilted at an angle of 23.5 degrees.
• This tilt is responsible for the changing of the seasons and the difference in the amount of sunlight reaching a given point on the surface during the course of a year.
• The tilt varies between 22.1 and 24.5 degrees in a cycle that averages about 40,000 years.

Explanation

• Rickets is a disease caused by a deficiency of Calcium and Vitamin D.
• It leading to softening of the bones in children.
• It can cause bowed legs, stunted growth, and skeletal deformities.

Explanation

• The average internal temperature of the human body is 37°C (98.6°F).
• Which is the normal body temperature range for a healthy adult.

Explanation

Explanation

• The electricity from a cell (such as a battery) is Direct Current (DC).
• It is the flow of electric charge in one direction only, without changing direction.

• Soft and weak bones
• Skeletal deformities
• Stunted growth
• Increased risk of fractures
