Answer:
The right answer to this question is water vascular system.
Explanation:
Through this system it's possible to identify it easily an echinoderm, that's why we can use it as a method of checking the information. But be careful, because for example, the radial symmetry, is not present in all the kinds of animals said on the question, shrimps are good examples, shrimps are part of the crustaceans. In this way, as you first see the organism, you are going to guess what it is by its appearance, and then you're going to analyse it properly after. Once you check it has a water vascular system, it's most probably to be an echinoderm.

This can be possible because we no longer need to use a large hose and spray water on the roads and let the dirty water drain away back into seas and rivers and create water pollution. However, this methods requires a large amount of labor and time.
<span>Extreme temperature and bedrocks
Tundra and desert both have shallow soil profiles because of the extreme temperatures and the bedrocks it has. In the case of tundra, it has extreme cold temperature and the soil were covered in ice in long periods of time. Because of this, the plants were unable to get water from the bedrocks resulting in plants dying. In the desert, however, it has extreme hot temperature making the plants unable to survuve due to lack of water in the environment and in the bedrocks. The plants that can only survive in this temperature are the plants that has the ability to store water in their system.</span>
