Science (086) — AI-generated practice question

A condom acts as a physical barrier that covers the penis, preventing direct contact between the body fluids and skin/mucous membranes of the partners. This blocks both sperm and disease-causing pathogens (bacteria, viruses) from being transmitted, protecting against pregnancy and STIs like gonorrhoea, syphilis, and HIV-AIDS.

A copper-T, however, is placed inside the uterus. It prevents pregnancy by creating an environment in the uterus unfavourable for implantation. Since it does not prevent the exchange of body fluids or skin contact during intercourse, it offers no barrier against STI-causing pathogens, leaving the person unprotected from sexually transmitted infections.

• The key distinction examiners look for is barrier vs. internal device: a condom prevents fluid/pathogen exchange; a copper-T only acts after sperm has already entered.
• Mention at least one example STI (gonorrhoea, HIV-AIDS) to show you've read the passage.
• The answer to the textbook question "If a woman is using a copper-T, will it help in protecting her from STDs?" is directly No—state this clearly and give the reason.
• Avoid copying long paragraphs; write in your own structured sentences for full marks.
