Question

question 11 1 pts planetary scientists and astrobiologists are particularly interested in finding liquid water on other planets because the presence of water on other planets tells us that those planets likely have an internal structure almost exactly like the earths. none of the above. we can date the age of a planet by its water content. life very likely began in the earths oceans, so the presence of water on other planets could indicate the potential for life on these planets.

Explanation:

Life on Earth likely originated in the oceans. Liquid water is a key ingredient for life as we know it. So, finding water on other planets may suggest the possibility of life there. The presence of water doesn't imply an Earth - like internal structure, and water content isn't used to date a planet.

Answer:

D. Life very likely began in the Earth's oceans, so the presence of water on other planets could indicate the potential for life on these planets.
