Person X is feeling a burning sensation in several muscles because of the accumulation of lactic acid due to inadequate oxygen in their system. When oxygen becomes inadequate during exercises, anaerobic respiration takes place to augment the oxygen shortage and this leads to the production of lactic acid which accumulates up in the muscles and gives a burning sensation.

$C_6H_1_2O_6 --> 2C_3H_6O_3$

Person Y does not feel any burning sensation in their muscles because oxygen is adequate in their system and they do not need to respire anaerobically. Person X exercise regime must have been more rigorous than that of person Y.

How long does it take for most fossils to form

luda_lava [24]

Answer:

10,000 years

Explanation:

Fossils are defined as the remains or traces of organisms that died more than 10,000 years ago, therefore, by definition the minimum time it takes to make a fossil is 10,000 years. But, that is just an arbitrary line in the sand – it means very little in terms of the fossilisation process.
