Question

A central idea in nasa confirms evidence that liquid water flows on today’s mars is that life cannot exist without water. which passage from the text best supports this central idea?

Answer 1

The passage that best supports the idea that life cannot exist without water states that Mars is the most promising place to look for life, and the guiding principle to assess habitability is to 'follow the water.'

Step-by-step explanation:

The passage from the text that best supports the central idea that life cannot exist without water is:

Of all the planets and moons in the solar system, Mars seems to be the most promising place to look for life, both fossil microbes and (we hope) some forms of life deeper underground that still survive today. But where (and how) should we look for life? We know that the one requirement shared by all life on Earth is liquid water. Therefore, the guiding principle in assessing habitability on Mars and elsewhere has been to "follow the water." That is the perspective we take in this section, to follow the water on the red planet and hope it will lead us to life.
