if you were able to send a test tube of one kind of extremophile to mars, which extremophile would you choos?

Answer 1

Temp on Mars 80F to -200F. There is scarce nutrients on Mars. A polyextremophile might be able to survive.

A polyextremophile (to like several extremes in more-or-less Greek) is an organism which combines several extremophilic features. For example, a polyextremophile living at the summit of a mountain in the Atacama Desert might be a radioresistant xerophile, a psychrophile, and an oligotroph.
