Well, the domain humans belong to (when I did a little research) is that they are actually a Eukaryote. Therefore, I'd say C, Eukarya. I hope this helps! ~Mia
Place mercury in the reactor. After a large amount of work, only a tiny portion of gold is created.
Decontaminate the resulting gold. This is harder than it sounds because you can't separate out non-radioactive gold from radioactive gold using purely chemical methods.
It should be obvious from this process that it currently costs much more money to create non-radioactive gold than you could ever earn by selling the gold. Creating gold from other elements is currently an expensive laboratory experiment and not a viable commercial activity. Perhaps technology will improve enough in the future to make creation of gold in nuclear reactors a profitable economic enterprise.
Based on a ruler in centimeters, with ten divisions between each centimer mark, you will have marks at every 0.1 cm.
Then, the measure of the length of a metal rod should have 1 decimal place.
That decimal place means mlimiters, given that 1 mm = 0.1 cm.
Answer: 1 decimal place
