Bats use echolocation, emitting ultrasonic waves that bounce off objects.

It allowing them to navigate and hunt in the dark.

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

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

Explanation

A free-falling object has an acceleration of 9.8 m/s/s, downward 

Explanation

Glaucoma is caused by an increase in pressure within the eyeball, specifically in the fluid pressure inside the eye.

This increased pressure can damage the optic nerve and lead to vision loss if left untreated.
