The tree species that was most often killed by A. ostoyae in control forests. Introduction: Parasitic fungi attack plants and withdraw nutrients from them. Armillaria ostoyae (honey mushroom) is an example of such a fungal parasite . They attack the root systems of living trees. When the tree dies, the fungal parasite survives on the dead remains. The hyphae that grow from roots of infected trees and dead stumps invade roots of healthy plants leading to infection.

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.

The metabolic pathway below is used for the production of the purine nucleotides adenosine monophosphate (AMP) and guanosine monophosphate (GMP) in eukaryotic cells. Assume each arrow represents a reaction catalyzed by a different enzyme. Using the principles of feedback inhibition, propose a regulatory scheme for this pathway that ensures an adequate supply of both AMP and GMP, and prevents the buildup of Intermediates A through G when supplies of both AMP and GMP are adequate.
