The half-life carbon-14 is 5730 years. archaeologists dig up a seed that contains 0.25 parts per trillion of carbon-14. if it originally contained 1 part per trillion carbon-14, how old is the archaeological specimen?

a) 11,460 years

b) 5730 years

e) 28,650 years

how do you get 11,460 which is the answer of to this problem?

d i think its   answer d

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.

this is a good question! i'll do some research and come back when i have the answer!

i won't lie i don't know so go online and ask google thats what i do
