Fish use gills to:
- A.
  
  Breathe
- B.
  
  Swim
- C.
  
  See
Correct Answer
A. Breathe

Explanation
Fish use gills to extract oxygen from water and release carbon dioxide. Gills are specialized respiratory organs that allow fish to breathe underwater. They are made up of thin, feathery filaments that have a large surface area for efficient gas exchange. As water passes over the gills, oxygen is absorbed into the bloodstream and carbon dioxide is expelled. This adaptation enables fish to live and survive in their aquatic environment.

Correct Answer
C. See

Explanation
Fish use their eyes to see their surroundings and navigate through their environment. The eyes of fish are adapted to function underwater, allowing them to detect light and distinguish shapes, colors, and movements. This visual information is crucial for their survival, as it helps them locate food, avoid predators, and find suitable habitats. Additionally, fish rely on their eyes to communicate with other members of their species through visual signals and displays. Overall, vision plays a vital role in the daily activities and survival of fish.
