Question

which consequences of sexual activity is abstinence 100% effective in preventing? check all that apply
unplanned pregnancy
sexually transmitted diseases
sexual feelings
transmission of hiv or aids
secretion of hormones

Explanation:

Abstinence (avoiding sexual activity) eliminates the risk of unplanned pregnancy (no sperm-egg contact), sexually transmitted diseases (no sexual contact with infected individuals), and HIV/AIDS transmission (no exposure to infected bodily fluids via sexual activity). Sexual feelings and hormone secretion are natural physiological processes unrelated to sexual activity, so abstinence does not prevent them.

Answer:

unplanned pregnancy, sexually transmitted diseases, transmission of HIV or AIDS
