In the reaction:

\[ \text{H}_2\text{Se} + \text{H}_2\text{O} \rightarrow \text{SeH}^- + \text{H}_3\text{O}^+ \]

we can identify the following:

- **Acid**: The substance that donates a proton (H⁺). In this reaction, **H₂Se** is the acid because it donates a proton to water.

- **Base**: The substance that accepts a proton. Here, **H₂O** (water) acts as the base since it accepts a proton from H₂Se.

- **Conjugate Acid**: The species formed when a base accepts a proton. In this case, the **conjugate acid** is **H₃O⁺** (hydronium ion), which is formed when water accepts the proton.

- **Conjugate Base**: The species that remains after an acid donates a proton. In this reaction, **SeH⁻** is the **conjugate base** formed after H₂Se donates a proton.

In summary:
- Acid: H₂Se
- Base: H₂O
- Conjugate Acid: H₃O⁺
- Conjugate Base: SeH⁻
