Question

name three major body systems that are affected by stimulants, and what * 1 point affected, can lead to various illness
heart rate, blood pressure, breathing rate
heart rate, muscular system, skeletal system
heart rate, integumentary system, urinary system
none of the above
determine the legal bac limit for someone who is over the age of 21, and * 1 point is driving a vehicle
.08
.01
0.1
0.8

Explanation:

For the first question, heart rate, blood pressure, and breathing rate are physiological parameters, not major body systems. The muscular and skeletal systems are major body systems but heart rate is a parameter. The integumentary (skin) and urinary systems are major body systems, but heart rate is a parameter. So none of the options correctly list major body systems affected by stimulants.
For the second question, the legal Blood Alcohol Concentration (BAC) limit for someone over 21 driving a vehicle in many places (e.g., in the US) is 0.08.

Answer:

First question: None of the above
Second question:.08
