Explanation

• Oranges are well-known for being rich in Vitamin C.
• It is essential for immune function, skin health, and other bodily processes.

Additional information 

• Vitamins are essential nutrients
• That your body requires in small amounts to function, grow, and develop properly.
• They are divided into two main groups:
• water-soluble (like Vitamin C and the B-vitamins)
• fat-soluble (like Vitamin A, D, E, and K)

Explanation

• Feathers and hollow bones make birds light for flight.
• Feathers provide lift, balance, and insulation.
• Hollow bones reduce body weight while remaining strong.
• These adaptations help birds fly efficiently and conserve energy.
• Most flying birds have hollow (pneumatic) bones.

Explanation

• A cell shrinks due to osmosis when placed in a concentrated salt solution.
• Water moves out of the cell into the salt solution through the cell membrane.
• This happens because the outside solution is hypertonic.
• As water leaves the cell, it loses volume and shrinks.
• This process is called osmosis.

Explanation

• MRI (Magnetic Resonance Imaging) is the best scan for detailed images of soft tissues, ligaments, and the brain.
• It uses strong magnets and radio waves.
• MRI provides highly detailed images of organs and soft tissues.

Additional information:

• CT Scan: Bones, internal bleeding, chest and trauma injuries
• X-ray: Broken bones, teeth, chest examination
• Ultrasound: Pregnancy and soft organs

Explanation

• During photosynthesis, plants absorb carbon dioxide (CO₂) from the atmosphere.
• They use carbon dioxide, water, and sunlight to prepare food (glucose).
• During this process, plants release oxygen (O₂) into the atmosphere.
• Photosynthesis mainly takes place in the chloroplasts of green leaves.

Explanation

• If ribosomes do not function properly, protein synthesis will stop.
• Ribosomes are the site of protein synthesis in all living cells.
• Proteins are essential for growth, repair, and cell functions.
• Without proteins, the cell cannot function or survive properly.
• Ribosomes are found in both prokaryotic and eukaryotic cells.

Explanation

• CT Scan provides cross-sectional (slice) images of both bones and soft tissues using multiple X-ray images.
• It is commonly used in complex trauma, internal bleeding, fractures, and organ injuries.
• CT stands for Computed Tomography.
• Inventor: Sir Godfrey Hounsfield (1972)
