Explanation

An inclined plane is a slanting surface connecting a lower level to a higher level.

It is a simple machine that helps to lift or move loads to a higher position, and is commonly used in:

• Ramps
• Staircases
• Slides
• Ski lifts
• Hilly roads

Explanation

• Camels have a special water storage space in their humps, which store fatty tissue.
• When food and water are scarce, the camel's body metabolizes the fatty tissue in the hump, providing energy and water.
• This allows camels to survive for extended periods without water.

Explanation

• The pupal stage of a bee is known as a Cocoon.
• This stage is characterized by a resting, non-feeding state, where the larva transforms into an adult bee.

Explanation

• The larval stage of a bee is known as a Grub.
• This stage is characterized by a legless, worm-like body, fed royal jelly and pollen by worker bees.

Explanation

• Smoking is the leading cause of lung cancer.
• It is responsible for about 80-90% of all lung cancer deaths.

Explanation

• The Earth rotates on its axis, completing one full rotation in 24 hours.
• This is the equivalent of 1,440 minutes or 86,400 seconds.
• This rotation is what gives us day and night, as different parts of the planet face towards or away from the Sun.

Explanation

• As a result of the flow of energy (heat) from a region of high temperature to a region of low temperature: the warmer materials cool down and cooler materials warm up.
• This flow of energy is known as heat transfer.
• It occurs through conduction, convection, and radiation.
  
• As a result, the warmer materials lose energy and cool down, while the cooler materials gain energy and warm up.

Explanation

Sodium is present in various foods, including:

• Meats (especially processed meats)
• Eggs
• Table salt (sodium chloride)
• Fruits (in small amounts)
• Vegetables (in small amounts)

Explanation

• The lungs are responsible for exchanging oxygen and carbon dioxide through the process of respiration.
• Oxygen from the air we breathe in is absorbed into the bloodstream.
• Carbon dioxide, a waste product, is removed from the bloodstream and exhaled out.

Explanation

• The nose not only takes in air from our surroundings.
• But it also warms, moistens, and filters the air before it goes to the lungs.
• The nasal passages contain tiny hairs called cilia and mucous membranes that help to trap dust, bacteria, and other particles, preventing them from entering the lungs.
