The vatican archives maintain a vault where century's worth of old documents are stored in very high n2 levels to prevent oxidat
Vinil7 [7]

The Vatican archives stores multiple precious documents and books of the world. These old documents dating hundred of years are kept in high nitrogen levels, in order to prevent the oxidation of the paper (papyrus). The presence of the high level of inert nitrogen in the air in the archives prevents any kind of damage that may caused to the paper or the ink on those documents. This high level of nitrogen, however, may affect the health of the individual by decreasing the oxygen levels in the body.

Hence, the answer is 'the oxygen level will be decreased in the body'.

1. Define fitness as it used to describe adaptation
aliya0001 [1]

Answer:

In terms of adaptation, fitness refers to the ability of an organism to survive and reproduce in a constantly changing environment.

Adaptive traits are very much important in a constantly changing environment as they increase the chances of survival of a population in the environment.

For example, Darwin's finches adapted to develop different types of beaks in order to get nutrition in different environments. Long necks of giraffes are also considered as a result of adaptation which helps them get the food located high on trees.
