Scientists discover remains of wooden structures near a Celtic runes site. What kind of testing will indicate when the stones were moved into place by the Celts?

1. Radioactive dating

2. Carbon dating

** THIS IS SCIENCE **

Option (2)

Explanation:

Celtic runes sites refers to some of the places in the northern part of Europe whose common scripts are the Celtic runes.

The remnants of wooden structures are discovered in this place by the scientists, and in order to determine the time, that is, when the stones were carried by the Celts into the mentioned place, the most efficient way of determining this time will be the carbon dating method.

The carbon dating method is efficiently used to date an object that are of very recent age. It is because the half life of carbon is approximately 5700 years, which is geologically a very small age.

Thus, the correct answer is option (2).

the answer is 1. photosynthesis. glad to

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
