If you are asked to design one micro life to introduce on mars, what is the prime characters do you think your microbe should contain?

The hypothetical micro life in mars must have 4 principal characteristics: anaerobiosis, desiccant resistant, psychrophilic and radiotolerence.

Explanation:

Mars has a very extreme environmental condition. The atmosphere of mars has about 95% of carbon dioxide and very low oxygen ( 0.18%),  minor amounts of water and the average temperature is about minus 80 degrees. Also, it has elevated radiation of its surface. The micro life must grow in the absence of oxygen ( called anaerobiosis), the ability to grow at very low temperatures ( called psychrophilic) and must be desiccant and radiotelorant to be able to survive.

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."

he forelimbs below belong to four species that descended in a direct line from the ancestral mammal shown above. of the four descendants shown, which species most likely appeared earliest in evolutionary history?
