The terms that describe a mixture of oxygen gas dissolved in water are:

- Solution: In this case, oxygen gas is dissolved evenly in water, resulting in a homogeneous mixture.
- Homogeneous mixture: This term refers to a mixture that has a uniform composition, such as a solution where the oxygen gas is dissolved in water.
- Liquid-gas: Describes the state of the two components in the mixture, water (liquid) and oxygen gas (gas).
- Gas-liquid: Similar to the term "liquid-gas", it refers to the state of the two components in the mixture, but with the order reversed.

The terms that do not apply in this case are:

- Heterogeneous mixture: A mixture that does not have a uniform composition. This term is not applicable because the dissolved oxygen gas is evenly distributed throughout the water.
- Suspension: A heterogeneous mixture in which solid particles are dispersed in a liquid. Since there are no solid particles involved in a dissolved gas, this term does not apply.

To determine which terms describe a mixture of oxygen gas dissolved in water, we need to understand the definition of each term and then analyze the situation.

1. Homogeneous mixture: This term describes a mixture where the components are uniformly distributed and not easily distinguishable. In the case of oxygen gas dissolved in water, the oxygen molecules are uniformly distributed throughout the water, making it a homogeneous mixture.

2. Solution: A solution is a type of homogeneous mixture where one substance is dissolved in another substance. In this case, when oxygen gas is dissolved in water, it forms a solution.

3. Heterogeneous mixture: This term describes a mixture where the components are not uniformly distributed and can be easily distinguished. Since oxygen gas dissolved in water forms a homogeneous mixture, it is not a heterogeneous mixture.

4. Suspension: A suspension is a type of heterogeneous mixture where solid particles are dispersed in a liquid or gas but do not dissolve. This term does not apply to a mixture of oxygen gas dissolved in water because the oxygen molecules dissolve in the water rather than being solid particles suspended in it.

5. Liquid-gas and gas-liquid: These terms describe the state of matter of the components in a mixture. In the case of oxygen gas dissolved in water, we have a gas (oxygen) dissolved in a liquid (water). Therefore, both liquid-gas and gas-liquid terms are applicable.

Based on the analysis, the terms that describe a mixture of oxygen gas dissolved in water are:
- Homogeneous mixture
- Solution
- Liquid-gas
- Gas-liquid

Therefore, the correct options are:
- Homogeneous mixture
- Solution
- Liquid-gas
- Gas-liquid
