Condensation is the phase change from gas to liquid. You can see condensation in the real world if you have a very cold drink. A bottle of water filled with ice will attract water vapor from the air, and it will condensate around the bottle because the temperature is lower, which facilitates the phase change. The outside of the bottle will contain a bunch of water droplets.

Answer:a) a sturdy-finned, shallow-water lobe-fin whose appendages had skeletal supports similar to those of terrestrial vertebrates.
Explanation:
An ancestor - An earlier type of a species at any distant time — a progenitor.
A tetrapod is any vertebrate with four limbs. It includes any vertebrate (such as birds or snakes) that have evolved from early tetrapods — especially all members of the superclass Tetrapoda.
The presence of bones that support the appendages in Lobe – fin fish were found to be similar to the categorical skeletal supports found in the limbs of sample tetrapods. The sub class crossopterygii includes the Lobe – fin fish, which is seen as one of the recent common ancestor of living tetrapod today.
