Final answer:
The provided data does not indicate a clear proportion of individuals exposed to ACEs who will become addicted to illicit drugs. Instead, the 'Effective Dose - 50%' refers to the dose that achieves a significant response in 50% of test subjects, commonly known as the ED50.
Step-by-step explanation:
The question relates to the effects of adverse childhood experiences (ACEs) on the likelihood of addiction to illicit drugs.
However, without specific data, it is not possible to accurately determine what proportion of the population exposed to at least one ACE will be addicted to illicit drugs.
This rate can vary widely based on many factors, including the type and severity of the ACEs, the individual's resilience, mental health, social support system, and access to substance use prevention and treatment services.
The Meaning of 'Effective Dose - 50%'
'Effective dose - 50%' describes the dose that results in a significant response in 50% of subjects (Option D).
This term is often used in pharmacology and toxicology studies to assess the effectiveness of a substance.
It is also known as the ED50, which is the median effective dose, and is a standard measure of a drug's potency.
