Q: Answer the following question given this paragraph: Accidentally introduced in the 1900s, the fungus decimated elm trees across the continent. Many European and Asiatic elms are less susceptible to Dutch elm disease than American elms. In humans, fungal infections are generally considered challenging to treat. Unlike bacteria, fungi do not respond to traditional antibiotic therapy, since they are eukaryotes. Fungal infections may prove deadly for individuals with compromised immune systems. Fungi have many commercial applications. The food industry uses yeasts in baking, brewing, and cheese and wine making. Many industrial compounds are byproducts of fungal fermentation. Fungi are the source of many commercial enzymes and antibiotics. Q: Many european and asiatic elms are less susceptible to dutch elm disease than which elms? Choices: - caribbean - rican - african - american A:
A: american

Q: Chemical reactions either require or release what? Choices: - light - electricity - enzymes - energy A:
A: energy
