Answer:
Robotic arms used aboard the ISS are now used in delicate surgeries on Earth.
Explanation:
The ISS allows users to address hardware product development gaps, advanced manufacturing, and emerging technology proliferation. Microgravity-enabled material production capabilities and advanced manufacturing facilities are demonstrating scientific and commercial merit for Earth benefit
A group of cells together
Answer:
basically they have too much mass in them
Explanation:
They are held tightly together by strong forces of attraction. They are held in fixed positions but they do vibrate. Because the particles don't move, solids have a definite shape and volume, and can't flow. Because the particles are already packed closely together, solids can't easily be compressed.
