Answer:
Domain Eukarya
Explanation:
There are only three domains; the Archaea, Eukarya, and Bacteria. Domain Eukarya came from the first prokaryotic cells billions of years ago.
Answer:
A quarter of the sample.
Explanation:
Let the quantity at the beginning be T. If the element has a half-life of 1,000 years, it means that after 1000 years, T/2 (which represents half the initial quantity available) would have decayed, remaining T/2.
After another 1000 years (making 2000 years), T/4 (which represents have of the quantity left after the first 1000 years) would have decayed, remaining T/4.
This means that only a quarter of T would be left after 2000 years.
I believe the answer is C (recycle them, but not through the regular trash disposal)
I hope this helps :)
