(b)प्रत्येक जीवत एकाच प्रमाणात 'C - 14' असतो. / Every living being has the same proportion of carbon 14.
(c)मृत्यूनंतर जीव एकाच प्रमाणात कार्बन फेकतो. / After death every living organ throws same percentage of carbon.
(d)अर्धा C - 14 मृत्यु नंतर 5568 वर्षांनी नाहीसा होतो ज्यास 'हाफ लाईफ ऑफ C - 14' (सी - 14 चे अर्धे आयुष्य) संबोधण्यात. / After 5568 yrs of death half of C - 14 will disappear - which is called as half life of carbon - 14.
