Explanation

A biome is a community of both plants and animals that occupy a specific habitat and are adapted to a particular climate and geography.

Biomes can be terrestrial (land-based), freshwater, or marine (ocean-based), and they can vary in size from small to global.

Biomes are composed of:

• Plants (flora)
• Animals (fauna)
• Microorganisms (such as bacteria and fungi)
• Physical environment (climate, soil, water, etc.)

Explanation

Skin regulates body temperature through sweating, blood flow adjustment, and insulation.

It helps maintain homeostasis by releasing heat or conserving warmth as needed.

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

Explanation

Hypothermia is caused by exposure to cold temperatures for a long time.

It can also occur after prolonged immersion in cold water. 

Causes 

Cold temperatures: Exposure to temperatures below 10°C for a long time

Cold water: Prolonged immersion in water below 20°C

Wet clothing: Wearing wet clothing in cold or windy weather

Heavy exertion: Exerting yourself while in cold weather

Dehydration: Not drinking enough fluids in cold weather

Undereating: Not eating enough in cold weather

Explanation

Fishes breathe with their Gills.

Gills are feathery organs full of blood vessels.

A fish breathes by taking water into its mouth and forcing it out through the gill passages

Explanation

"The branch of biology that deals with organisms living in the ocean is called marine biology."
:
The term Marine Biology is used to refer to the study of marine organisms and ecosystems.

Explanation

Vitamin D deficiency can cause Rickets, a disease characterized by:

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