Answer 1

QUESTION 1

The correct answer is DNA, associated species information, location information, habitat type. In fact, the information that is labelled on each specie of the herbaria is:

•Date

•Place where it was found

•Description of the specimen

•Altitude

•Special habitat conditions

This information allows us to determine the approximate location of the specie and its habitat. On the other hand, the specimen in herbaria are also used as source of DNA information for taxonomy. Even the ancient fungi are a valuable source of DNA.
