For the leaves to be presearved as fossil, they have to undergo a natural process of carbonization. This involves a slow chemical reaction with water over time that allows oxygen, nitrogen, and hydrogen to escape the leaves’ structure as gases leaving behind a carbon skeleton/film.

To preserve the leaves that are put in a forest floor the leaves have to be dehydrated and put in 10% formalin.

<u>Explanation:</u>

The tissues or any organelles that are got form any organism contains a lot of hydration in them; it is the water content that makes them vulnerable to contamination.

In order for the leaves to remain like fossils, they must be naturally carbonated. This involves a slow chemical reaction with water, allowing oxygen, nitrogen and hydrogen to escape from the leaf structure as the gas leaves the carbon atoms.  

The contamination is caused by the bacteria that grow on these leaves by feeding on the hydration and organic content of the material, when this is fixed using an organic solvent then there is no room for contamination.

the size difference between most multicellular hosts and their pathogens results in which of the following evolutionary advantag
professor190 [17]

Pathogens can adapt more quickly than hosts since they have higher populations and faster generation periods.

Pathogens, of course, have the advantage in this evolutionary game because they can change far more quickly than the hosts—especially in long-lived animals like humans—due to their high population numbers and rapid generation rates. The relationship between surface area and complement activation shows how bacterial pathogenicity may be influenced by tiny size. The region of the microbial surface may also have a role in their action since other antimicrobial agents are focused there. A pathogen reacts with the host and creates infection, which results in the host being ill. Any dangerous microbial agent, including bacteria, viruses, protozoa, fungi, and helminths, might be considered a pathogen.
