Final answer:
Increased biological risk relates to the trigger level by representing an elevated chance of negative outcomes due to exposure to risk factors.
Step-by-step explanation:
In biology, increased biological risk refers to the elevated chance of experiencing negative outcomes or health events due to exposure to risk factors. The trigger level represents a threshold or point at which the risk factor is activated, potentially leading to the increased biological risk. For example, if the trigger level is reached, individuals in the exposed group may be 3.25 times more likely to experience the health event compared to those in the non-exposed group.
