Answer 2

Answer:

(i) Yak - thick hair on the skin.

(ii) Cactus - fleshy stem.

(iii) Water hyacinth - Air spaces in stems.

(iv) Rohu - Gill.

Explanation:

• Central Asia is home to the yak, a member of the cow family with long horns and long hair.
• A perennial plant is a cactus. Their cylindrical or flattened stalks are covered in meat or succulents. The photosynthetic, green stems typically serve this purpose instead of the leaves, which are typically much diminished in number or entirely nonexistent in most adult cacti.
• In most of the world's frost-free zones, water hyacinth is a common freshwater weed and is thought to be the most problematic aquatic plant.
• A species of fish belonging to the carp family called the rohu, rui, or Roho labeo is found in South Asian rivers. It is a sizable omnivore that is widely cultivated.
