Sounds like infectious would fit.
Living things are based on a universal genetic code. All organisms store the complex information they need to live, grow, and reproduce in a genetic code written in a molecule called DNA. That information is copied and passed from parent to offspring and is ALMOST identical in every organism on Earth.
Because those are traces of life meaning that there was life living there once, that life wouldn't have been able to survive there with how Antarctica is now.
Boys need 2,400 to 3,200 a day, while girls need 1,800 to 2,400 a day.
Hope this helps!
