Answer:

Due to environmental conditions.

Explanation:

With the passage of time, environmental conditions change which causes the evolution of of four legged land animals from fish like creature. This change occurs due to change in environment. In water, there is no need for legs because fish moves with the help of fins and tail but the organisms that lives on land has legs in order to move from one place to another so we can say that change in the physical structure of organism occurs due to environment.

Tom [10]

Answer: d - water forming on the lid under the container

Explanation:

Condensation is the process that describes the change of state of water from gas to liquid. It happens in the water cycle when water vapor gets to the atmosphere and due to the lower temperatures turns into liquid water that then forms clouds.

In the demonstration, the container is meant to be the clouds so when water forms under the container, that is condensation happening because the water vapor has not turned back to liquid after leaving the aquarium water as water vapor.
