Question
- A. They release hormones to inhibit ovulation
- B. They block sperm from entering the uterus
- C. They kill sperm on contact
- D. They prevent the implantation of an embryo
Answer
The correct option is They block sperm from entering the uterus. This answer is correct because it matches the approved learning objective to describe barrier methods such as condoms and diaphragms as methods that prevent sperm reaching an egg in the subtopic Contraception.
Explanation
The correct option is They block sperm from entering the uterus. They block sperm from entering the uterus is correct because it directly supports the approved learning objective to describe barrier methods such as condoms and diaphragms as methods that prevent sperm reaching an egg. This belongs to the subtopic Contraception within Hormonal coordination in humans, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from Contraception.
Common mistake
Misunderstanding Barrier Methods
Students often confuse barrier methods with hormonal methods of contraception, thinking they work by altering hormone levels.
Remember that barrier methods, like condoms and diaphragms, physically block sperm from reaching the egg, rather than affecting hormone production.
