Diffusion is a form of Response area cell transport. The model/illustration shows a Response area gradient. The solution has reached Response area when the movement of particles from A to Response area is the same as from Response area to A. When the temperature is Response area, the molecules move faster - but still move Response area their own concentration gradient.

It looks like you're referring to a section of an educational resource about facilitated diffusion. Here's how you might fill in the blanks based on standard biological concepts:
Facilitated diffusion **does not** require ATP, and requires **protein** channels. These are also called **transport proteins**, which bring molecules across the cell membrane from areas of **high** concentration to areas of **low** concentration **down** (or **along**) the concentration gradient.
Diffusion is a form of **passive** cell transport. The model/illustration shows a **concentration** gradient. The solution has reached **equilibrium** when the movement of particles from A to **B** is the same as from **B** to A. When the temperature is **higher**, the molecules move faster - but still move **down** their own concentration gradient.
