A Correct answer
Explanation

The bath sponge (Spongia) has a skeleton composed of spongin fibers. When the living tissue is removed and the sponge is dried, only the spongin fiber network remains.

Multiple choice

Materials for rain proof coats and tents owe their waterproof properties to

  1. surface tension

  2. viscosity

  3. specific gravity

  4. elasticity
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Waterproof fabrics often rely on the hydrophobic nature of their coating, which increases the contact angle of water droplets. This phenomenon is governed by surface tension, preventing water from penetrating the pores of the material.

  2. Latex

  3. Fiber

  4. All of these
Reveal answer Fill a bubble to check yourself
D Correct answer
