What are nails made from?
- A.
  
  Melanie
- B.
  
  Keratin
- C.
  
  Gelatin
- D.
  
  Melatonin
Correct Answer
B. Keratin

Explanation
Nails are made from keratin, a tough and flexible protein found in the outer layer of our skin, hair, and nails. Keratin provides strength and protection to our nails, allowing them to grow and withstand daily wear and tear. It is the main component of the nail plate, giving it its hardness and durability. Gelatin is derived from collagen and is used in various products, but it is not the primary material that nails are made from. Melatonin is a hormone that regulates sleep-wake cycles and has no relation to nail composition.

Correct Answer
B. Summer

Explanation
During the summer season, nails tend to grow faster. This is because warmer temperatures increase blood circulation, which in turn promotes nail growth. Additionally, exposure to sunlight during the summer months helps in the production of vitamin D, which is essential for nail health and growth. Therefore, the combination of increased blood flow and adequate vitamin D levels during summer accelerates nail growth.

Correct Answer
A. Hardness of Your Nail

Explanation
The hardness of your nail is genetic because it is determined by the genes that you inherit from your parents. The genes control the production of keratin, which is the protein that makes up your nails. Different variations in these genes can result in variations in nail hardness among individuals. Therefore, the hardness of your nail is a genetic trait that can be passed down through generations.
