Ineed asap im on a in what way has technology used aboard the international space station benefitted humans back on earth? 1. robotic arms used aboard the iss are now used in delicate surgeries on earth. 2. air purifiers developed for the iss now provide cleaner air for humans on earth. 3. software created for the iss was adapted and is now used to conduct brain surgery on earth. 4.research conducted on the iss crew about heart disease is now used to patients on earth.

Option 1,  Robotic arms used aboard the ISS are now used in delicate surgeries on Earth.

Explanation:

The robotic arm on the international space station is used in conducting surgery. The first space robotic arm was launched in 2001 and its name was “Canadarm 2”. Though the aim of this arm was to construct space station but now a days it is used in imaging the surgical work area and instruments through its camera. The best feature of this hand is that it follows the instruction with high efficiency and precision level.

Hence, option 1 is correct.

Option 1,  Robotic arms used aboard the ISS are now used in delicate surgeries on Earth.

Explanation:

good thing- during decomposition the organic molecules in organic matter are broken down into simpler organic molecules that require further decomposition or into mineralised nutrients

bad thing- it can be harmful in crop productivity
