Final answer:
Birth control pills prevent pregnancy by stopping ovulation but do not prevent STIs, which is a false belief. While using condoms reduces the transmission risk of STIs, it does not guarantee complete prevention due to possible breakage or improper use.
Step-by-step explanation:
The statement that birth control pills help prevent pregnancy also prevent STIs is False. Birth control pills work by preventing ovulation and are an effective form of contraception, but they do not offer protection against sexually transmitted infections (STIs). Some STIs that often go unnoticed due to a lack of symptoms include Chlamydia and Human Papillomavirus (HPV). In contrast, the proper use of condoms can significantly reduce the risk of transmitting STIs, although they cannot completely prevent transmission as there is still a possibility of failure due to breakage or improper use, and they cannot protect against infections that may be transmitted through skin contact not covered by the condom.
