Question

which is not a high - risk behavior that puts a teen at risk of std/stis? engaging in unprotected sexbeing sexually active with more than one partnerpracticing abstinenceusing alcohol or other drugsusing the birth control pill as the only form of protectionoccasionally using protection during sexwhich is not a consequence of contracting stds? improved immune systemsterilitycancerdamage to the health of unborn childrenphysical signs like sores or burning during urination

Explanation:

• For the first question: Unprotected sex, multiple sexual partners, using alcohol/drugs (impairs judgment), using birth - control pill only (doesn't protect against STDs), and occasional protection all increase STD risk. Abstinence means no sexual activity, so no risk of STDs from sexual contact.
• For the second question: STDs can cause sterility (e.g., untreated chlamydia), cancer (e.g., HPV - related cervical cancer), harm to unborn children (e.g., congenital syphilis), and physical signs like sores (e.g., herpes) or burning during urination (e.g., urethritis). They do not improve the immune system.

Answer:

• First question: Practicing abstinence
• Second question: Improved immune system
