Question

Which statement describes how technology has increased our information on Mars?

Answer 1

Answer:

The correct statements are that the Curiosity rover found sulfur compound in rocks, and detected carbon in organic molecules.

Explanation:

The Curiosity rover detected methane gas in the atmosphere of Mars as well as organic substances from shallow-soil samples from Gale crater. Both the soil compounds and methane gas are organic matter. The organic matter is chemically illustrated as combinations of hydrogen, carbon, and other elements basically witnessed in biology like oxygen and sulfur, that is, usually related to life.  

At certain times, the rocks can get produced on their own via the geological procedures. However, discovering organic matter in such large concentration indicates that it potentially exhibit biological origins, either from bacteria or other life forms, which prevailed long ago.  

Answer 2

The Curiosity rover found sulfur compounds in rocks and carbon in organic compounds like propane, butene, benzene, toluene and thiophene.

It detected methane, not in soil samples, but in the Martian atmosphere.

It did not discover helium in underground pockets. The hole it can drill is only 5 cm deep.
