One property you could measure is its solubility. Knowing whether or not it dissolves in water will help you narrow down the possible substances it could be.

Another is density. Using the volume and mass, you can calculate density. This will also narrow down the possible substances.

The anterior portion of the body of most annelids, such as the earthworm, is adapted for sensing the environment.
Diano4ka-milaya [45]

Answer:

The answer is False. Although sensitive cells are <u>more abundant</u> in the <u>anterior portion</u> of the annelid´s body, in general, they are arranged in all the segments.

Explanation:

Annelids, such as the earthworm, have a variety of sensory cells:    

  • <u>Mechanoreceptors</u>, disposed of in groups in <em><u>each segment</u></em> of their body.  
  • <u>Photoreceptors</u>: Light-sensitive cells. Although they are <em><u>located in the whole </u></em>body, they are <em><u>abundant in anterior and posterior segments</u></em>, concentrated in the intern and dorsal part of the epidermis.
  • <u>Humidity receptors</u> are the most sensitive cells and are <u>located in the first segments</u> of the earthworm body
  • <u>Chemoreceptors</u>: sensorial cells cumulus forming a prominent tubercle with prolongations that extends through the cuticle. These tubercles form three rings <em><u>in each segment</u></em> but are especially <em><u>abundant in the anterior part</u></em> of the body.

The tegument is very rich in free nervous terminations, which functions might be tactile.
