Final answer:
Baseline activities in a daily routine that can be replaced with health-enhancing activities include taking a brief walk after work or engaging in moderate-intensity aerobic activity for at least 30 minutes a day. On the other hand, baseline activities that may not be feasible to replace include necessary household chores and work-related tasks that require sedentary behavior.
Step-by-step explanation:
Baseline activities in a daily routine that can be replaced with health-enhancing activities include taking a brief walk after work or engaging in moderate-intensity aerobic activity for at least 30 minutes a day. For example, instead of sitting during breaks at work, one can take a walk. This helps increase physical activity and improves overall health. On the other hand, baseline activities that may not be feasible to replace include necessary household chores and work-related tasks that require sedentary behavior.
