□ the motility of a specimen can be viewed under a microscope.
□ no special equipment is needed.
□ the specimen can be viewed as living cells.
□ the contrast of a specimen is enhanced with the addition of water to the slide.

Explanation:

• For "The motility of a specimen can be viewed under a microscope": A wet mount keeps the specimen in a liquid environment, allowing for the observation of movement (motility) of organisms like bacteria or protozoa.
• For "No special equipment is needed": Wet mounts are prepared with basic lab equipment (slide, coverslip, water, specimen), no specialized tools beyond a microscope (which is standard for viewing) are required.
• For "The specimen can be viewed as living cells": The wet mount preserves the specimen in a natural, hydrated state, so living cells retain their normal structure and function for observation.
• The statement about contrast enhancement is incorrect because water alone does not enhance contrast; stains or other techniques are used for that. So the first three options are correct.

Answer:

A. The motility of a specimen can be viewed under a microscope.
B. No special equipment is needed.
C. The specimen can be viewed as living cells.
