Verified step by step guidance

1. Step 1: Begin by identifying the context of the question. Zak is attending an annual health checkup, which is focused on monitoring his overall health.
2. Step 2: Evaluate each option provided in the question to determine its relevance to Zak's health. For example, the classification of extinct animal species and the structure of DNA in bacteria are unrelated to personal health monitoring.
3. Step 3: Consider the option 'Recent changes in his diet and exercise habits.' This is directly related to Zak's health and provides valuable information for his doctor to assess his overall well-being.
4. Step 4: Analyze the remaining option, 'The process of photosynthesis in plants.' While scientifically interesting, it is not relevant to Zak's health checkup.
5. Step 5: Conclude that the most appropriate topic for Zak to discuss with his doctor is 'Recent changes in his diet and exercise habits,' as it directly impacts his health and allows for effective monitoring.
