Using anabolic steroids to increase muscle and strength:Group of answer choicesis a normal part of adolescence: 100% of teenage boys use this.shows no ethnic difference: boys from all backgrounds use them equally.can cause heart attacks from high blood pressure and high cholesterol.makes testicles grow larger.

The correct answer is: "can cause heart attacks from high blood pressure and high cholesterol."

Anabolic steroids are synthetic substances similar to the male hormone testosterone. They do have legitimate medical uses. However, they are often misused by athletes and bodybuilders to increase muscle mass and improve performance, but this can lead to harmful and potentially deadly side effects.

One of the major risks associated with anabolic steroid use is cardiovascular disease. Steroids can increase blood pressure and cholesterol levels, which can damage the heart and potentially lead to a heart attack.

The other options are incorrect:

• Using anabolic steroids is not a normal part of adolescence and it's not true that 100% of teenage boys use them. Steroid use is actually quite dangerous, especially for teenagers whose bodies are still developing.

• There's no evidence to suggest that boys from all backgrounds use steroids equally. Steroid use varies widely among different groups and is influenced by a variety of factors.

• Anabolic steroids do not make testicles grow larger. In fact, they can cause the opposite effect. Long-term steroid use can lead to testicular shrinkage.
