Answer

To solve the question regarding the effects of biodiversity loss, we will evaluate each of the given statements one by one.

### Step-by-Step Solution:

1. **Gene Pool of a Species**:
- The gene pool refers to the total genetic diversity found within a population. When biodiversity is lost, the number of individuals in a species decreases, leading to a reduction in genetic variation. This loss can result in the extinction of unique genes, thereby diminishing the gene pool.
- **Conclusion**: This statement is true.

2. **Number of Interactions in the Biota**:
- Biodiversity contributes to the complexity of interactions among species, such as predator-prey relationships, competition, and mutualism. The extinction of a species can disrupt these interactions, leading to a decline in the overall number of interactions within the ecosystem.
- **Conclusion**: This statement is true.

3. **Ability of Species to Adapt to Changes in the Environment**:
- The ability of a species to adapt is largely dependent on the genetic variation present within its population. A loss of biodiversity reduces this genetic variation, making it more difficult for species to adapt to environmental changes.
- **Conclusion**: This statement is true.

4. **Non-Evolutionary Advancements**:
- Non-evolutionary advancements refer to traits that are already present in an organism and do not rely on ongoing evolutionary processes. These traits would not be affected by biodiversity loss, as they exist independently of the genetic diversity of the population.
- **Conclusion**: This statement is false.

5. **The Surviving and Newly Evolving Species to Dangers of Extinction**:
- While biodiversity loss can threaten existing species, it does not inherently reduce the ability of newly evolving species to adapt or survive. Evolution can continue in the face of biodiversity loss, as species may develop new adaptations to survive.
- **Conclusion**: This statement is false.

### Final Answer:
Based on the evaluations, the correct statements regarding the reduction caused by the loss of biodiversity are:
1. Gene pool of a species.
2. Number of interactions in the biota.
3. Ability of species to adapt themselves to changes in the environment.

Thus, the correct answer is **1, 2, and 3**.
