Answer 1

Answer:

1. Plants like cactus and acacia are able to survive in desert places because of the special features they contain. They have got needle like leaves which reduces the rate of transpiration rate hence plants are able to store the little water for a long period of time. They have got thick stems for storage of water.

2. Plants in snowy regions have needle like leaves to conserve water by decreasing the surface area of the leaves. Also, the have cone shaped canopy so that snow does not cover the stomata on the leaves by settling on it.

3. In order to live on land, amphibians replaced gills with another respiratory organ, the lungs. ... Because frogs are amphibians, they have adaptations that help them live on land and in water. They are cold blooded, which means that their body temperatures change with that of the environment.
