Answer:

1 Fish gills are organs that allow fish to breathe underwater. Most fish exchange gases like oxygen and carbon dioxide using gills that are protected under gill covers (operculum) okn both sides of the pharynx (throat). Gills are tissues that are like short threads, protein structures called filaments.

2 The leaves of 'cactus' are reduced to 'spines' to prevent the loss of water by transpiration. EXPLANATION: Leaves lose water by the process of transpiration but cactus grows in deserts and cannot afford to lose water. The spines of the cactus store water.
