The condition of birds and mammals having four limbs is a shared ancestral character because the structure of the limbs are similar in both the cases.

A tree that has leaves that are shaped to help water drip off them would most likely live where?
Elena-2011 [213]

Answer:

The correct answer is tropical rain forests.

Explanation:

The hot and moist biome witnessed close to the equator of the Earth is the tropical rainforest. The largest tropical rainforests in the world are found in Africa, South America, and Southeast Asia. About 60 to 160 inches of rainfall is witnessed in the tropical rainforests throughout the year. Due to this, the leaves of the trees found in the tropical rainforests possess unique features that help them to survive.  

The leaves of the trees found in the tropical rainforest possess drip tips that help them to cope with the extreme amount of rainfall that takes place throughout the year. The drip tips help the drop of rains to run off briskly from the surface of the leaves. This adaptation helps the plants in the region to prevent the growth of bacteria and fungus.
