2. Random assignment of subjects: To ensure unbiased results, sea lions should be randomly assigned to different experimental groups. This helps to minimize any pre-existing differences among the groups that could potentially influence the results.

3. Control group: A control group should be established, consisting of sea lions that are not exposed to any toxins. This allows for comparisons to be made between the effects of toxin exposure and normal neurological development.

4. Experimental group: Another group of sea lions should be exposed to a controlled dose of toxins that are known to occur in their habitat. The exposure can be achieved through carefully controlled conditions, such as administering the toxins orally or through environmental exposure.

5. Data collection: During the experiment, data should be collected to assess the neurological development of the sea lions in each group. This can be done through various methods, such as behavioral observations or neuroimaging techniques. The data should be collected at regular intervals over a specified period of time to track the effects of the toxins on the sea lion’s neurological development.

6. Statistical analysis: Finally, the data collected from the different groups should be analyzed using appropriate statistical techniques to determine if there are any significant differences in the neurological development between the control and experimental groups. This analysis will help to establish the effects of toxins on the sea lion’s neurological development, allowing for conclusions to be drawn.

Overall, a well-designed experiment following these steps would help determine the effects of toxins on the neurological development of sea lions. It is essential to conduct such studies to better understand the impacts of toxins on wildlife and implement measures to protect their health.
