Carbon-14 has a half life of about 5700 years. how useful is it in dating ancient fossils?

Radioactive dating is used to measure the carbon-14 content in the ancient fossil or specimen. This carbon-14 or radiocarbon is a naturally occurring substance which is formed when the cosmic rays in the atmosphere strikes the nitrogen atoms which then oxidizes to form carbon dioxide. This carbon dioxide is taken by plants and is also transferred to the animals feeding on them. After the death of organism, the amount of carbon -14 decreases as the organism decays. It has a half life of 5700 years which means that the carbon 14 decays reduces to half in amount after 5700 years. Fossils from the last 70,000 years which were made up of wood, charcoal, bone can be dated using this technique.

the answer is admiramos

the rule for verbs is whoever you are referring to (in this case 'nosotros'), you need to change the ending of the word.

nosotros - amos

yo - o

tu - as

el, ella, usted - a

ellos, ellas, ustedes - an

(examples: nosotros bailamos (instead of bailar) or yo hablo (instead of habla)
