Answers
fossil is that you have catch it at oil at 200 years
Answer:
i. Remnants and impressions of organisms which get buried and remain preserved underground are called fossils. Study of fossils is an important aspect of study of evolution.
ii. Carbon consumption of animals and plants stop after death and since then, only the decaying process of C-14 occurs continuously.
iii. In case of dead bodies of plants and animals, the ratio of C-14: C-12 changes continuously instead of remaining constant as C-12 is non – radioactive.
iv. The time passed since the death of the plant or animal can be calculated by measuring the radioactivity of C -14 and the ratio of C-14 to C-12 present in their body.
v. This is carbon dating method. It is used in determining the age of human fossils and manuscripts.
vi. Once the age of the fossil is determined, it becomes easy to deduce information about the erstwhile organisms.
vii. It seems that vertebrates have slowly originated from invertebrates.
