which phrase accurately characterizes sexually transmitted infections (stis)?\n○ are caused by bacteria, viruses, or parasites\n○ always cause visible symptoms\n○ are rarely transmitted by sexual contact\n○ can be contracted only by women
Answer
Brief Explanations:
To determine the correct phrase for STIs:
- Option 1: STIs are caused by bacteria (e.g., chlamydia), viruses (e.g., HIV), or parasites (e.g., Trichomoniasis) – this is accurate.
- Option 2: STIs do not always have visible symptoms (e.g., many asymptomatic cases exist) – incorrect.
- Option 3: STIs are primarily transmitted by sexual contact, so "rarely" is wrong – incorrect.
- Option 4: STIs can be contracted by both men and women – incorrect.
Answer:
A. are caused by bacteria, viruses, or parasites
