Why have scientist devised a system of comparative weights for atoms rather than using actual weights

Biology
1 answer:
tatuchka [14]2 years ago
5 0

Answer:

Because of multiple reasons:

Explanation:

  1. Atoms are way too small to weigh.
  2. They couldn't use weight, they would have to use mass.
  3. Some atoms are free-floating, because they are the air.
  4. If they even made a scale that measured each atom, it would also catch the air atoms as well, unless they had a vacuum chamber, but even then, no one can make a perfect vacuum, space is not even a perfect vacuum...

Hope this helps.

  • The cattle is incapable of producing this cellulase enzyme by itself and is dependent on the micro-organisms for its synthesis.
  • Hence, the the micro-organisms help the cattle in obtaining nutrition and energy by the digestion of cellulose.
