Cuboidal …………………………….. of collecting tubule is permeable to …………………………….. and impermeable to salts.

Explanation

To answer the question, we need to fill in the blanks regarding the characteristics of the cuboidal epithelium in the collecting tubule.

1. **Identify the type of epithelium**: The collecting tubule is lined with cuboidal epithelium. This type of epithelium consists of cube-shaped cells that are involved in various functions, including secretion and absorption.

2. **Determine permeability**: The cuboidal epithelium of the collecting tubule is permeable to water. This means that it allows water to pass through its cells.

3. **Determine impermeability**: The cuboidal epithelium is impermeable to salts. This indicates that salts cannot pass through the cells of the cuboidal epithelium in the collecting tubule.
