Question

1. microscopic organisms that live within other organisms, namely people or animals, and are spread through contaminated water used in the growing or preparation process of food are referred to as:

○ viruses.

○ dna.

○ parasites.

○ protozoa.

Explanation:

To solve this, we analyze each option:

• Viruses: While some viruses are intracellular, the description of spread via contaminated water in food processes and "microscopic organisms living within others" better fits parasites or protozoa, but viruses aren't typically described as organisms in the same way (they're acellular).
• DNA: Not an organism, so eliminated.
• Parasites: Organisms that live in/on another organism (host) and derive nutrients, can be spread via contaminated water in food. This matches the description.
• Protozoa: Some protozoa are parasites, but the term "parasites" is a broader category for organisms living within others and spreading via such means. The key is the definition of an organism living within another (host) and transmission route. Parasites (including some protozoa) fit, and "parasites" is the most direct term for this relationship.

Answer:

C. parasites.
