21. **C) Nucleus** - The nucleus is a primary target for antifungal drugs because it is essential for fungal cell replication and survival.<br /><br />22. **C) Hyphae** - Hyphae are the long, branching filaments that make up the structure of molds and are responsible for their fluffy appearance.<br /><br />23. **C) Viruses undergo binary fission.** - This statement is incorrect. Viruses do not undergo binary fission; they replicate by hijacking the host cell's machinery to produce new viral particles.<br /><br />24. **C) The lowest temperature at which the microorganisms grow** - Minimum growth temperature is the lowest temperature at which a microorganism can grow.<br /><br />25. **A) Pyruvic acid** - Pyruvic acid is a common universal intermediate in metabolic pathways.<br /><br />26. **A) True** - It is true that about a dozen of fungi are responsible for approximately 90% of all fungal diseases.<br /><br />27. **B) False** - The statement is false. Fungi do not grow ONLY in yeast or mold morphology; they can exhibit various forms depending on the conditions.
