Question

With liquid water underneath its icy surface, Jupiter’s moon Europa is often cited as a potential site for extraterrestrial life. What other compounds would indicate that chemosynthesis supports life on the planet?(1 point) Responses methane methane glucose glucose hydrogen peroxide hydrogen peroxide oxygen

Answer 1

In addition to liquid water, the presence of certain compounds can indicate potential for chemosynthesis and support for life. Among the options you provided, methane and hydrogen peroxide would be relevant.

• Methane can be an indicator of biological processes or geological activity that could support life.
• Hydrogen peroxide might serve as an oxidant, which can be utilized by certain organisms in chemosynthesis.

Oxygen could also be a strong indicator of life, especially if it is found in conjunction with other compounds that suggest biological activity.

So, the most relevant compounds from your list considering the context of potential life-supporting chemosynthesis would be methane and hydrogen peroxide.
