Answer 2

Answer:

b) Mold spores

Explanation:

In biology, a spore is a structure of sexual and asexual reproduction made by an organism or species to propagate itself (dispersal) or to survive for a long time under extreme conditions. Spores are an important part of the life cycle of many plants, algae, fungi, and protozoa. Bacteria also form spores, called endospores, which are not part of any reproductive cycle, but a passive contractile structure designed to keep bacteria alive in difficult conditions. Some parasites inject different types of spores into the bodies of other organisms, which develop within those organisms. The key potential sources of fecal bacteria are animal waste from agricultural operations.
